Because of proliferating questions to “how can I work with copy of KSDK example” or “I am not successful with creation new MQX project with SDK, what I do wrong?”   I decided to do this this short step by step tutorial.   To do this procedure is needed the script, which creates Anthony Huereca and bat file created by me. Thanks to it is possible to create copy of any example which is based on KSDK. This script allows to work with real copy of KSDK example, which is choosen. It can be called like working copy. It is possible to edit any example and  build on this demo user´s own application. It is also much easier than e.g. creating new MQX project, which is quite lengthy process – always must think of correct settings paths, including libraries etc. In this situation is everything copyied (compiler settings, linker, preprocessor…) First of all is describe the utilization of the script. The script renames the original name of the demo to new one. So, user gets full-fledged copy. The main essence of the matter is that the script must be in location with other examples. I hope it helps a lot of us. Iva

I created easy tutorial for UART KSDK blocking demo which works as echo. The demo works with KSDK 1.1. and is created for KDS 2.0.   Because it could be problem if was used this pin by this reason was chosen UART 3, which is available to use and is routed to PTC16,PTC17 connection on Arduino header for this case is use ALT3 function (PTC16, PTC17)   Final output from terminal Physical connection between FRDM-K64F and USB to Serial Converter The unzipped folder must be located in example folder at C:\Freescale\KSDK_1.1.0\demos\

Hello community:   This document shows how to integrate a basic NFC (Near Field Communication) library to a KSDK project and explain its use with a simple demo project.   INTEGRATING NFC CONTROLLER LIBRARY   These instructions are based in the files usually present in a KSDK project. If your project has a custom source file structure, just add the referenced code accordingly.   1- Open the file gpio_pins.c and add 2 pin configurations: 1 input pin called NFCCirqPin and 1 output pin called NFCCvenPin:   gpio_input_pin_user_config_t NFCCirqPin = {    .pinName = kGpioNFCCirq,    .config.isPullEnable = false,    .config.pullSelect = kPortPullUp,    .config.isPassiveFilterEnabled = false,    .config.interrupt = kPortIntDisabled, }; gpio_output_pin_user_config_t NFCCvenPin = {    .pinName = kGpioNFCCven,    .config.outputLogic = 1,    .config.slewRate = kPortSlowSlewRate,    .config.driveStrength = kPortLowDriveStrength, };‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍   2-  In the file gpio_pins.h add 2 extra elements to the gpio enumeration. Also add extern declarations for the 2 pins defined in the previous step.   NOTE: In this example the selected pins are PTB16 as IRQ and PTB17 as VEN. The pins depend on your routing from the Kinetis MCU to the NFC Controller board.   enum _gpio_pins {    kGpioLED1 = GPIO_MAKE_PIN(GPIOD_IDX,  5),  /* FRDM-KL43Z RBG LED Green LED */    kGpioLED2 = GPIO_MAKE_PIN(GPIOE_IDX, 31),  /* FRDM-KL43Z RBG LED Red LED   */    kGpioSW1 = GPIO_MAKE_PIN(GPIOA_IDX,  4),  /* FRDM-KL43Z SW1 */    kGpioSW3 = GPIO_MAKE_PIN(GPIOC_IDX,  3),  /* FRDM-KL43Z SW3 */    kGpioNFCCirq = GPIO_MAKE_PIN(GPIOB_IDX,  16), /* GPIO for NFCC IRQ pin */    kGpioNFCCven = GPIO_MAKE_PIN(GPIOB_IDX,  17), /* GPIO for NFCC VEN pin */ }; extern gpio_input_pin_user_config_t NFCCirqPin; extern gpio_output_pin_user_config_t NFCCvenPin;‍‍‍‍‍‍‍‍‍‍‍‍   3- In the file pin_mux.c define a function to configure the MUX setting of the required GPIO and I2C pins to interface with the NFC controller.   NOTE: The configured pins must correspond to the routing from the Kinetis MCU to the NFC controller board. In this case PTB16/PTB17 are set as GPIOs while PTE0/PTE1 are configured for I2C functionality. For I2C pins also check the MUX number in the device's Reference Manual (e.g. PTE0/PTE1 in KL43 have the I2C function in ALT6.   void configure_nfcc_pins(void) {    /** I2C_SDA **/    PORT_HAL_SetMuxMode(PORTE,0u,kPortMuxAlt6);    /** I2C_SCL **/    PORT_HAL_SetMuxMode(PORTE,1u,kPortMuxAlt6);    /* NFCC IRQ */    PORT_HAL_SetMuxMode(PORTB,16u,kPortMuxAsGpio);    /* NFCC VEN */    PORT_HAL_SetMuxMode(PORTB,17u,kPortMuxAsGpio); }‍‍‍‍‍‍‍‍‍‍‍   4- Add the prototype of the function to header file pin_mux.h.   /* ** =================================================== **     Method      :  configure_nfcc_pins */ /*! **     @brief **         Set mux configuration for I2C and GPIO pins **         to interface with the NFC Controller. */ /* ==================================================*/ void configure_nfcc_pins(void);‍‍‍‍‍‍‍‍‍‍‍   5- Add the NfcLibrary and TML folders with all its subfolders and files to your project's tree, so the library is part of the build. Also add the include paths to your compiler for the inc folders. Below an example with Kinetis Design Studio:                - Now the project is ready to use the NFC controller library. The library uses the next conditional compilation macros, add or remove these symbols from the compiler's preprocessor settings as required:   CARDEMU_SUPPORT: The NFC Controller host (MCU) emulates a contactless card which can be accessed by an external Reader/Writter. P2P_SUPPORT: The host MCU can establish a 2-way communication accesing to or sending information to an external Reader/Writter. RW_SUPPORT: With this mode the host can access a remote contactless tag/card via the NFC Controller. NCI_DEBUG: If defined, all information transfered between the host MCU and the NFC Controller Interface (commands, responses, notifications, data) is echoed to console for debug purposes.     DEMO PROJECT   The attached project is based on the application note AN11658 NXP-NCI NullOS integration example. So you can refer to the appnote for detailed information.   Software The project was developed with the next software versions:   - KSDK v1.3 - KDS v3.0.0 :smileyinfo: NOTES: -The KSDK platform library for the KL43 must be built before the example project. Otherwise the build fails due to library file missing (libksdk_platform.a). - Once the example project is imported please verify that the build variable PROJECT_KSDK_PATH is pointing to your KSDK v1.3 installation path.   Hardware - For the NFC part, I used the NFC Controller board from the OM5577, which is a demonstration kit for the PN7120 NFC controller Interface chip. - To interface with the NFC Contoller I used a FRDM-KL43Z Freedom board.     How to use the demo   R/W mode:   -  Placing a tag with a single text, URI or vCard NDEF record next to the NFC reader. Examples:                P2P mode:   - Bring an android phone with NFC enabled close to the NFC controller antenna and use the "beaming" feature. In the case below the NXP home page is "beamed" from the adroid phone's explorer:                     CARD EMULATION mode     For this mode it is required to remove the P2P_SUPPORT macro and rebuild/reprogram the project.   - Bringing an android phone set to read a NFC tag close to the NFC controller board:     I hope you like this document. Any questions or doubts please let me know in the comments.   Jorge Gonzalez NXP Technical Support

Hardware and software configuration: FRDM-K22F, SCH-28164 REV D OpenSDA: J-Link firmware KDS 3.0 with SDK 1.2.0 Eclipse update installed KSDK 1.2 provides an Eclipse update for those who want to use the Kinetis SDK with Eclipse and Processor Expert. and with this update , users may find MSD Class component has been supported, and there is a simple USB mass storage demo available directly in this PEx USB component, so that customers may easily build this demo and develop their own application based on that. Here I will start to illustrate how to implement this demo step by step. As FRDM-K22F is used in this test, so I directly choose this board and make the following configuration: After above steps, we have a PEx project with some pre-installed components as shown below: clockMan1 components has 6 configurations , and one of it is for USB application, you may set it as the init configuration right now, or it would be set automatically when you add the USB MSD components. Now I find the MSD component from KSDK 1.2 and add it to my project: This component will add 4 more reference components into this project, and we only have to configure the component "fsl_debug_console" to get rid of the error mark. For FRDM-K22 board, UART1 is used as the debug console, and PTE0 and PTE1 are used as the TXD and RXD, so I set up this components as below: The simple MSD demo is a RAM disk demo, and it is disabled by default, so we have to enable it in the fsl_usb_device_msd_class component, and the demo code will be automatically added into the project afterwards: and then set the correct PID and VID information in the component of fsl_usb_descriptors. so far looks like all components are configured correctly , but if we directly download this application, we will have an enumeration issue like below: This is due to USB descriptors are placed to Flash memory area by default . You know , USB descriptors contain constant values so storing them in flash would leave more RAM for user application. The highlighted option in the following figure determines this . but USB module in Kinetis doesn't have the permission for flash out of reset, so we still have something to do before going ahead. There are several solutions for it, the most easiest way is setting the above option to "no", but we may do it in a PEx-like way by using the "Init_FMC" component. Please note USB is the M4 of K22's crossbar-lite. so we give it the "read only" permission. Init_FMC() is placed in Peripherals_Init() which is called right before  Components_Init() where USB_Class_MSC_Init () is in, so it guarantees USB have the flash access permission before it starts up. Now the demo can work well with the PC host, just as shown below: So far only HID and MSD Class components are supported, and if you go through a similar process as above, you may easily implement a HID demo by yourself. Here I attach both the MSD and HID mouse demo for your reference. Hope that helps,

MCUXpresso Pins Tool allows you to configure pin routing and generates ‘pin_mux.c & h’ source files. This article describes how to configure Pins in a FreeRTOS project with MCUXpresso pins tool.  In this example, pin PTC9 on Freedom-k66 board is configured.   Software and Tools In this article, I’m using the following: MCUXpresso IDE 10.2.1   www.nxp.com/mcuxpresso ,  MCUXpresso SDK 2.4.1 for  Frdm-k66f  board.  With Amazon FreeRTOS v10 .You can get it from https://mcuxpresso.nxp.com FRDM-K66 board www.nxp.com/frdm-k66f First, we need to have a working FreeRTOS project. Here we import the freertos_hello example into MCUXpresso IDE workspace. To open the tool, simply right click on the project in Project Explorer and select the appropriate open command. Then we can see the pin table, peripheral signals, package/pinout view, Routed pins view, generated code view. Basic configuration can be done in either of these views Pins, Peripheral Signals or package. More advanced settings can be adjusted in Routed Pins view. Beginning with Peripheral selection In the Pins view on the left find a pin and peripheral signal in the table and configure the routing by clicking on the signal cell.   In this example, select PTC9.  Click into the cells to make them ‘green’ Select PTC9 on the Peripherals signals view, Routed Pins configure Route the selected signal to the desired pin,and configure it in the Routed Pins view. It is possible to easily identify routed pins/peripherals in the package using highlighting. By default, the current selection (pin/peripheral) is highlighted in the package view. State Indicator of Pin Tool Green indicates pin/peripheral is routed Yellow indicates pin/peripheral is currently selected Red indicates an error Light grey indicates pin/peripheral is available but is not currently routed. It is also possible to configure the pin electrical features. Use the table drop down menu to configure the pin. To configure pins, start from left to right—select the peripheral first, then select required signal, and finally select the routed pin. Code generation  The Pins Tool automatically generates the source code for pin_mux.c and pin_mux.h on the right panel of the Code Preview view. The configuration will be saved into .mex file, see picture below Export the code.   You can now copy-paste the content of the sources to the application and IDE. Alternatively, you can export the generated files. To export the files, select the menu  Export Click Next and specify the directory, Click Finish to export the files. Integrate code the FreeRTOS task In the source code, Board_InitBootPins() calls initial code in pin_mux.c/h In hello world task, we toggle the configured pin /*!  * @brief Task responsible for printing of "Hello world." message.  */ static void hello_task(void *pvParameters) {     for (;;)     {         PRINTF("Hello world.\r\n");         /* Toggle LED. */         GPIO_PortToggle(BOARD_LED_GPIO, 1U << BOARD_LED_GPIO_PIN);         vTaskDelay(200);     } }   Then run the example, we can see LED is toggled every 200ms.   For information about how to create an FreeRTOS project with MCUXpresso IDE, please see the following document https://community.nxp.com/docs/DOC-341972  For information about configuring with MCUXpresso peripheral tool in an FreeRTOS project, please see the following document. https://community.nxp.com/docs/DOC-341986

The latest Kinetis SDK 1.1.0 supported HID bi-directional communication, the new API USB_Class_HID_Recv_Data() can be used to receive data from USB HOST. But without demo and test tool, customer still has no idea about how to enstablish such kind of communication in their application. I create a simple demo derived from existed hid_keyboard project, together with basic endpoint read/write test by Bus Hound. The demo is built and tested on my FRDM-K64F and can be port to other USB Kinetis device as well. Working steps: 1) Unzip attached code and project to C:\Freescale\KSDK_1.1.0\usb\example\device\hid folder. 2) Compile project (IAR) and download to FRDM-K64F via CMSIS-DAP debugger. 3) Open Bus hound, enter "Devices" table and uncheck all box and check "auto select hot plugged devices". 4) Plug USB cable and connects to PC, will found the device is checked in bus hound device tree. 5) Double click device, and select OUT endpoint to send 16 bytes to device. 6) Observe the g_OUT_ep_buf[]'s change in firmware (Demostrate receive function only)

Hi folks,   I would like to share my experience using lwIP with KSDK1.2, I hope this will be useful for people who is getting started with this TCP/IP stack.   I must admit that I really dislike working over an example application (please do not misunderstand my message, these examples are really nice but just as examples, not to develop new applications over them), the problem is that these project are not stand alone and if they are moved from their original locations it becomes a mess. This is why I always create a standalone projects. For instance I will describe how to run ‘lwip_tcpecho_demo’ and after this, how to reproduce this example as a standalone project.   Running ‘lwip_tcpecho_demo’ Creating a new project with lwIP support using FreeRTOS       I hope you find it useful.   Regards, Carlos

Kinetis SDK 1.1.0 is now officially released! You can download it via the big "Download" button on the KSDK website at http://freescale.com/ksdk   There are Windows and Linux 32-bit and 64-bit installers available. KSDK 1.1 will install in a new directory, which by default is C:\Freescale\KSDK_1.1.0, and will not interfere with previous installations of KSDK except to (optionally) update the Windows KSDK_PATH variable used by Kinetis Design Studio.   A high-level overview of what's new in KSDK 1.1 can be found in the Kinetis SDK 1.1 Release Notes but the most significant changes are: Additional devices supported Atollic TRUEStudio 5.2 is now supported Driver, HAL, and Platform Updates   There were also some other notable changes: GCC Make System Directory layout CMSIS-DAP/OpenOCD debug configurations now provided by default for KDS MQX for KSDK now included as option in the KSDK installer MQX Kernel 5.0.1 now supports lightweight configuration option   Details: 1)      Additional Devices The following devices are supported by Kinetis SDK 1.1 FRDM-K22F FRDM-K22F-K02* FRDM-K22F-K02 64* FRDM-K64F FRDM-KL03Z FRDM-KL46Z TWR-K22F120M TWR-K22F120M-K02* TWR-K24F120M TWR-K60D100M TWR-K64F120M TWR-KV10Z75M TWR-KV31F120M TWR-KV31F120M-KV30*   *These boards do not physically exist, but you can use the associated board to develop code for the subset devices listed. So for instance, if you're interested in the K02 device, use the FRDM-K22F for evaluation but use the K02 libraries provided to write code which will run on the K22F since it is a superset device.   2)      Atollic TRUEStudio 5.2 support   3)      Driver, HAL, and Platform Updates The HAL, Driver, and Platform code was updated with additional features, bug fixes, and enhancements. Several new peripherals are also supported which are listed in the Kinetis SDK 1.1 Release Notes. The Kinetis SDK v.1.1 API Reference Manual.pdf contains the latest KSDK API, and look at the updated demo projects for how to use the updated features like the power manager. There is now also the option to copy or not copy the vector table from ROM to RAM based on the linker file configuration using the ‘__ram_vector_table__’  argument in your IDE linker settings.   4)      GCC Make Changes Compiling with GCC now uses CMAKE.  Details on how to setup your system for compiling with GCC can be found in the GCC section of the <KSDK_path>/doc/Getting Started with Kinetis SDK (KSDK).pdf document. If you have "C:\MinGW\msys\x.x\bin" in your PATH variable (as required by KSDK 1.0.0), remove it to ensure that the new GCC build system works correctly.   5)      Directory Layout The HAL, Driver, and platform directory layout was slightly changed so that all the include files are now in a single directory instead of separate directories. This makes it simpler to add the include path into projects, and can also improve library compile times (by up to 50%). The KSDK platform library has also been slightly renamed to libksdk_platform.a   6)      CMSIS-DAP Debug Configuration OpenOCD debug configurations in Kinetis Design Studio are now provided by default for boards that use OpenSDAv2. OpenOCD makes use of the CMSIS-DAP debug protocol.   7)      MQX for KSDK Installer The Kinetis SDK 1.1 installer now includes options to install full MQX for KSDK support. The installation screen has also made it clearer during installation on how to select this option. There will no longer be a separate MQX for KSDK installer like there was for KSDK 1.0.   😎      MQX 5.0.1 Kernel Support of MQX Lite configuration and new example application rtos/mqx/examples/. There are provided options for creating tasks from statically allocated memory and application can define these tasks before MQX RTOS starts (using create_task() API). More changes are detailed in the MQX Release Notes in <KSDK_Path>/rtos/mqx/doc/Freescale MQX RTOS for Kinetis SDK Release Notes.pdf   This is just a high level overview of the changes, and should make developing applications using Kinetis SDK easier than ever.

The operating principle of this sensor consists in sending IR pulses and according to the existing distance between it and the reflective object, it generates different output voltages. Its analog output varies from 0.4 to 2.6 V approximately; the higher output voltage values are reached when the reflective object is closer to the sensor and the lower ones when it’s farther. The range of distance measured goes from 15 to 100 cm, if the distance from the sensor to the reflective object isn’t between this range, the demo’s results will not be reliable. The following figure depicts the application’s block diagram Figure 1. Block Diagram The signal received from the sensor goes through the Channel_1 at the instance 0 of the ADC module (ADC0_CH1), which is periodically triggered by the low power timer (every 125 µs). After getting every ADC’s sample an average is calculated from a total of 32 samples in order to make the ADC’s value reliable before using it to calculate the current distance. The application’s schematic diagram is shown in the following figure Figure 2. Schematic Diagram The required electrical connections to implement the application are explained below Table 1. Electrical connections   The following figure shows the application’s flow diagram    Figure 3. Flow Diagram   The required configuration for the ADC initialization in the application is shown on the following code snippet static int32_t init_adc(uint32_t uiInstance) {     /*      * Initialization ADC for      * 10bit resolution, interrrupt mode, hw trigger enabled.      * normal convert speed, VREFH/L as reference,      * disable continuous convert mode.      */     ADC16_DRV_StructInitUserConfigDefault(&adcUserConfig);     adcUserConfig.intEnable = true;     adcUserConfig.resolutionMode = kAdcResolutionBitOf10or11;     adcUserConfig.hwTriggerEnable = true;     adcUserConfig.continuousConvEnable = false;     adcUserConfig.clkSrcMode = kAdcClkSrcOfAsynClk;     ADC16_DRV_Init(uiInstance, &adcUserConfig);      /* Install Callback function into ISR. */     ADC_TEST_InstallCallback(uiInstance, CHANNEL_0, MyADCIRQHandler);      adcChnConfig.chnNum = IR_SENSOR_ADC_CHANNEL;     adcChnConfig.diffEnable = false;     adcChnConfig.intEnable = true;     adcChnConfig.chnMux = kAdcChnMuxOfA;     /* Configure channel0. */     ADC16_DRV_ConfigConvChn(uiInstance, CHANNEL_0, &adcChnConfig);      return 0; }             Here is the initialization of the ADC, the interrupt mode is enabled assigning the ‘true’ value to the variable adcUserConfig.intEnable, 10bit resolution is selected by kAdcResolutionBitOf10or11, the hardware trigger is enabled and the continuous conversion disabled with adcUserConfig.hwTriggerEnable and adcUserConfig.continuousConvEnable, respectively. Moreover, the selected clock source is asynchronous, kAdcClkSrcOfAsynClk. After these comes the call to the function ADC16_DRV_Init that receives as parameters the ADC uiInstance being used and a pointer to the structure adcUserConfig that contains the configuration selected by the user. The function ADC_TEST_InstallCallback installs the callback for the interrupt, its parameters are the uiInstance, the CHANNEL_0 from which will be received the interruption trigger and the name of the interruption handler function, MyADC1IRQHandler. The configurations for the ADC reading channel are the selection of the channel number adcChnConfig.chnNum (in this case it is being used the CHANNEL_1), the differential mode is disabled with the variable adcChnConfig.diffEnable, the trigger interrupt is enable at adcChnConfig.intEnable and with adcChnConfig.chnMux the channel multiplexer for a/b channel is selected by kAdcChnMuxOfA. Finally, the call to the function ADC16_DRV_ConfigConvChn receives the uiInstance number, the CHANNEL_0 for receiving the interrupt trigger and a pointer to the structure adcChnConfig that configures the ADC channel. The ADC trigger source initialization is presented below void init_trigger_source(uint32_t uiAdcInstance) {     lptmr_user_config_t lptmrUserConfig =     {         .timerMode = kLptmrTimerModeTimeCounter,         .freeRunningEnable = false,         .prescalerEnable = false, /* bypass prescaler */         .prescalerClockSource = kClockLptmrSrcMcgIrClk, /* use MCGIRCCLK */         .isInterruptEnabled = false     };      /* Init LPTimer driver */     LPTMR_DRV_Init(0, &lptmrUserConfig, &gLPTMRState);      /* Set the LPTimer period */     LPTMR_DRV_SetTimerPeriodUs(0, LPTMR_COMPARE_VALUE);      /* Start the LPTimer */     LPTMR_DRV_Start(0);      /* Configure SIM for ADC hw trigger source selection */     SIM_HAL_SetAdcAlternativeTriggerCmd(gSimBaseAddr[0], uiAdcInstance, true);     SIM_HAL_SetAdcPreTriggerMode(gSimBaseAddr[0], uiAdcInstance, kSimAdcPretrgselA);     SIM_HAL_SetAdcTriggerMode(gSimBaseAddr[0], uiAdcInstance, kSimAdcTrgSelLptimer); }            The user configuration for the LPTMR is located at the structure lptmrUserConfig, here the LPTMR Time Count mode is selected by kLptmrTimerModeTimeCounter, the free running mode, the prescaler and the timer interrupt are disabled with freeRunningEnable, prescalerEnable and isInterruptEnbled, respectively. Furthermore, the LPTMR clock source is selected as the Internal Reference Clock with kClockLptmrSrcMcgIrClk. The function LPTMR_DRV_Init receives as parameter the instance number, a pointer to the structure lptmrUserConfig that contains the user configurations and a pointer to the structure gLPTMRState with internal information of the LPTMR driver. The function LPTMR_DRV_SetTimerPeriodUs set the corresponding timer period for the LPTMR, its parameters are the ADC instance and LPTMR_COMPARE_VALUE that saves the period value in us. The LPTMR_COMPARE_VALUE macro is located and can be set at the lptmr_trigger.c file. Moreover, the user will be able to change this period during the execution time at the Variable Watch section in the FreeMASTER project, modifying the value of LPTMR Interrupt Time (us) and setting the LPTMR Time Flag on 1. LPTMR_DRV_Start starts the LPTMR and its only parameter is the ADC instance.                                           Finally, there are three functions that configure the SIM for the ADC hardware trigger source selection; they receive as parameters the array initializer of SIM peripheral base addresses, gSimBaseAddr[0], and uiAdcInstance. The function SIM_HAL_SetAdcAlternativeTriggerCmd enables/disables the alternative conversion triggers; in this case it receives a true value, so it is enabled. Moreover, SIM_HAL_SetAdcPreTriggerMode selects the pre-trigger source; its third parameter is kSimAdcPretrgselA that corresponds to Pre-trigger A. The last one, SIM_HAL_SetAdcTriggerMode, selects the trigger source, so it’s receiving kSimAdcTrgSelLptimer. The following code snippet shows the implemented algorithm to calculate the distance void GetCurrentDistanceValue(uint32_t uiAvgAdc) {     static uint32_t sdwCurrentDistance = 0;      uint32_t dwm = 0;     uint32_t dwb = 0;      if((520 <= uiAvgAdc) && (uiAvgAdc < 840))     {       dwm = 641;       dwb = 683970;     }     else if((260 <= uiAvgAdc) && (uiAvgAdc < 519))     {       dwm = 1337;       dwb = 1011000;     }     else if((130 <= uiAvgAdc) && (uiAvgAdc < 259))     {       dwm = 2941;       dwb = 1423500;     }     sdwCurrentDistance = (dwb-(dwm*uiAvgAdc));     g_dwDistanceIntegers = (sdwCurrentDistance/10000);     g_dwDistanceTenths = ((sdwCurrentDistance - (g_dwDistanceIntegers*10000))/1000); }            The implemented algorithm to calculate the distance is based on the division of the characteristic curve of the IR Sensor’s behavior in three different sections in order to approximate it to a linear behavior. Each line was generated from two different points. The first line is used when the uiAvgAdc value is between 520 and 840 (15 - 35 cm). The second one, for an uiAvgAdc value higher than 260 and lower than 519 (40 - 65 cm). And the last one, for uiAvgAdc values between 130 and 259 (70 - 100 cm). Depending on the calculated uiAvgAdc value, the slope (dwm) and the intersection with the y axis (dwb) change for each line.   In order to make the demo compatible with different microcontrollers and IDEs, it was necessary to avoid the use of float variables to calculate the distance, so that the result could be printed on a console without problems. The real values of the slopes and intersections with the y-axis for each line were multiplied by 10000. After getting sdwCurrentDistance value it is divided into integers and tenths; to get the integers at g_dwDistanceIntegers, the current distance is divided by 10000 and the corresponding fraction for tenths is stored in g_dwDistanceTenths. As a result, the current distance value is printed combining the integers and tenths variables, avoiding the use of a float variable.        The following graphic shows the characteristic curve and the three lines in which it was divided Figure 4. Characteristic curve’s graphic The application test’s results are shown in the following table 1 The error for the Distance Measured values is approximately ± 0.5 cm 2 The ADC Average values have an error of approximately ± 5 units Table 2. Test’s Results Steps to include IR sensor software to KSDK In order to include this demo in the KSDK structure, the files need to be copied into the correct place. The distance_measure_IRsensor folder should be copied into the <KSDK_install_dir>/demos folder. If the folder is copied to a wrong location, paths in the project and makefiles will be broken. When the copy is complete you should have the following locations as paths in your system: <KSDK_install_dir>/demos/distance_measure_IRsensor/iar <KSDK_install_dir>/demos/distance_measure_IRsensor/kds <KSDK_install_dir>/demos/distance_measure_IRsensor/src In addition, to build and run the demo, it is necessary to download one of the supported Integrated Development Enviroment (IDE) by the demo: Freescale Kinetis Design Studio (KDS) IAR Embedded Workbench      Once the project is opened in one of the supported IDEs, remember to build the KSDK library before building the project, if it was located at the right place no errors should appear, start a debug session and run the demo. The results of the distance measurement will be shown by UART on a console (use 115 200 as Baud rate) and at FreeMASTER, just as in the following example where the reflective object was located at 35 cm from the IR sensor: Figure 5. Example of the distance measured being shown in a console Figure 6. Example of the ADC Values obtained from the IR sensor monitored with FreeMASTER Figure 7. Example of the distance measured results at FreeMASTER FreeMASTER configuration For visualizing the application’s result on FreeMASTER it is necessary to configure the corresponding type of connection for the FRDM-K64F: 1. Open FreeMaster. 2. Go to File/Open Project. 3. Open the Distance Measurement IR Sensor project from <KSDK_install_dir>/demos/distance_measure_IRsensor/ FreeMaster. 4. Go to Project/Options. 5. On the Comm tab, make sure the option ‘Plug-in Module’ is marked and select the corresponding type of connection.    Figure 8. Corresponding configurations FRDM-K64F’s connection at FreeMASTER It is also necessary to select the corresponding MAP file for the IDE in which will be tested the demo, so: 6.  Go to the MAP Files tab. 7.  Select the MAP File for the IAR or the KDS project. *Make sure that the default path matches with the one where is located the MAP file of the demo at your PC. If not, you can modify the path by clicking on the ‘…’ button (see Figure 9) and selecting the correct path to the MAP file: <KSDK_install_dir>/demos/distance_measure_IRsensor/iar/frdmk64f/debug/distance_measure_IRsensor_frdmk64f.out <KSDK_install_dir>/demos/distance_measure_IRsensor/kds/frdmk64f/Debug/distance_measure_IRsensor_frdmk64f.elf 8.  Click on ‘OK’ to save the changes. Figure 9. Selection of the MAP File for each IDE supported by the demo I hope this demo to be useful for your applications, enjoy!

This document includes two chapters , chapter 1 is about how to use printf() to print string in KSDK1.3 project , the usage in project without MQX has been introduced on another document, you can find it here : https://community.freescale.com/docs/DOC-104349 , so in this DOC I only introduce how to use the printf() in KSDK MQX- Lite and KSDK MQX-Standard project .   Chapter 2 introduces how to check which UART port is used when use printf() to print string on the FRDM board and TOWER board .   In sum, only the project of “MQX standard” use it own driver for printf(), so we need delete the driver “fsl_debug_console”. In other SDK+PE projects , they all use the driver of “fsl_debug_console” for printf().

Sharing a porting guide for the USB CCID demo from using EMVSIM module on K8x/KL8x to more general UART-ISO7816 module on Kinetis K devices. The demo has been tested with K64 tower board and one internal tower card named as TWR-ISO7816, MK64 is connected directly with smart card connector without using external PHY.   Attached the porting guide and associated demo code based on KSDK2.0.   When running the demo code, you will see console log similar as in attached log file. After installing driver according to the readme file with the USB CCID demo, you will see something as follows in device manager for smart card. Then you can use the PC test tool "Snooper" to talk to smart card.     Hao Original Attachment has been moved to: USB_CCID_MK64.zip Original Attachment has been moved to: USB-CCID-log.txt.zip
