This manual explains how to create a project in CW and add components to Processor Expert. It also includes a couple of examples to print and get data with the printf and scanf functions from the stdio library by using Serial component (UART).

Recently I have received a report which said the customers met compiling issue when they imported the an2295sw CW project file and started to build it, the error message is like the following: When I looked into this issue, I found it was mainly due to some asm source file which was dedicated for Keil wrongly included in the CW project , so there would syntax error during compiling, and the linker issue was due to the path of linker file was wrongly defined, fix them would solve most of the compiling. 1. Fix source file issue: deselect the bootloader.asm file. 2. Fix linker file issue: redefine the correct path for linker file There is also an exception when you try to compile with the configuration for K70 120MHz part, it is due to some files can not be opened because the including path are missing: so besides the above changes, you have to add the paths below to solve this issue for Kinetis 120MHz part.    BTW, during debugging, I also found it is not convenient to switch between different configurations because users have to choose the proper header file for different platforms manually, so I add the following changes to support automatic switching platform according to the configuration but just with an exception for Kinetis K-1M 100MHz part, which still have to choose the proper platform manually. Customers who have downloaded an2295sw may directly replace the following files with that I attached in this document, which have included all above changes mentioned. an2295sw\src\Kinetis\CW_10.3\AN2295_Kinetis\.project an2295sw\src\Kinetis\CW_10.3\AN2295_Kinetis\.cproject an2295sw\src\Kinetis\CommonSource\bootloader_cfg.h Hope that helps, Kan

The document describes how to port yaffs2 file system for MQX. The detailed porting user guide can refer to the attached doc which use TWR-K70F120M as example. The reference code can be found in the attached source code package. Now, the yaffs2 for MQX can support NFC and non-NFC at the same time, the only difference is NAND driver. For NFC, you should use NFC driver and for non-NFC, you should use softnand driver. In yaffs2 porting package, include the files which should be modified in MQX release package. user_config.h should be placed at \config\platform name\ init_nandflash.c should be placed at \mqx\source\bsp\platform name\ \nandflash is the NAND driver, should be at \mqx\source\io\ \yaffs2 is the yaffs2 porting codes should be at the root directory of MQX release package softnand2K.c is the NAND driver for non-NFC(simulated by flexbus).

I recently developed a Visual Studio .NET application that uses an OpenSDA virtual serial port to communicate with a FRDM-K64F. My serial protocol is a binary command-response protocol, which means that every time the .NET application sends a command packet to the serial port, it should always receive a response packet back. You can find more details about the protocol in the Freescale Intelligent Sensing Framework, but for the purposes of this document, all that matters is that every command should receive a response. My Visual Studio .NET application uses the SerialPort class, and worked beautifully...until I changed the OpenSDA firmware. Originally I used OpenSDA firmware from P&E; this time I had tried out Segger. In theory, this change should not have made a difference, however with the Segger firmware my .NET application never received response packets. I knew that the command packets were transmitting correctly from PC to board because they would turn a board LED on and off as expected. I tried using a binary terminal, RealTerm, to send commands to see if it would receive responses, and it did. So the problem had to be in my .NET application. After a lot of googling and some trial-and-error, I ultimately found that enabling the Data Terminal Ready (DTR) signal did the trick. Strangely, I didn't need to enable DTR in RealTerm. The moral of the story is that if you want to use Segger OpenSDA with a .NET SerialPort, then you must enable DTR. Fortunately this configuration also works with P&E and mbed OpenSDA.

This is a port of the TWR_K60N512 "Audio" Demo into Kinetis Design Studio and into eGUI 3.0 (from 2.1). The original demo is from Petr Gargulak and was under "Freescale_embedded_GUI_SW.zip\_Official_Demos\EGUI_D4D_Demo\TWR_K60N512\BareMetal\CW_10_1" avaiable on the freescale website. Some of the major porting differnces (this may help others porting similar projects): KDS: KDS by default does not define 'asm()', switch these to '__asm()' or change compiler settings (see: Sorting out asm(); in KDS: How to change your compiler language to GNU ISO90) eGUI 2.1 -> 3.0: Autosize feature has gone, all object sizes now need to be declared Objects seem to add padding of some sort: even with objects where size was previously declared, these had to be increased by ~3px in each direction, else text/images would not render. 'D4D_OBJECT_SYS_FUNCTION' structure no longer contains 'type'. It suggests using strName instead to identifier object. D4D_TEXTBOX no longer has title or icon functionality. When building this project there will be ~7 warnings from the compiler, including 2 of my own. The code should function fine. note: TWR_LCD settings for this project, switches are set up with in following sequence: "01111110". regards, Rael S-R

最近有客户问到如何移植PE生成的TSI代码到IAR中，按照常规的方法在把头文件和库文件意义一一包含进来，非常繁琐，于是研究了一下相关的操作。在早期的IAR版本中，需要用户自己手动添加芯片名称，链接文件和包含的路径信息，特别是在PE增加或者删除组件后，需要用户去增减相应的文件，更增加了难度。而在最新版本的 IAR 6.7中集成了对PE工程的链接机制，它可以方便的读取PE工程的XML文件，从而实现移植PE生成的代码到 IAR Embedded Workbench中，相对于早期的IAR版本，主要完成以下几个工作： 自动检测使用的芯片类型； 自动添加PE的LCF连接配置文件； 自动更新包含的头文件路径； PE增加或者删除Component组件后，IAR工程会自动Add 或Delete 相应的组件代码； 尽管IAR完成了一些繁琐的工作，但网上没有太多的资源可以参考，对于首次使用的用户来说还是需要一些探索，为节省大家的时间，下面以一个具体的示例Step By Step的介绍如何在IAR中集成PE的工程。 1. 打开Processor Expert software 新建一个PE的工程并保存生成代码，这个过程比较简单，此处不再赘述，重点讲述一下在IAR中的使用步骤； 2. 在IAR Workbench中"Creat New Project"新建一个空的工程。 3. 保存新建的工程文件到PE工程的文件夹中，需要注意的是此处也可以选择其他路径，但为简便和易维护性上还是建议直接存放到PE工程中。 4. 打开Tools->Options->Project选项，勾选“Enable project connects”，这个选项的目的在于使能 IAR 能够读取Freescale Processor Expert和Infineon DAVE等第三方工具生成.XML文件。 5. 添加PE工程的XML文件，选择Project->Add Project Connection，会弹出链接选择对话框，选择使用Freescale Processor Expert，默认是IAR Project Connection； 6. 点击OK后，选择建立PE工程时生成的工程描述符文件Projectinfo.xml； 7. 完成上面步骤后，在IAR中自动完成以下三方面工作：自动加载PE生成的文件到IAR中，自动安装LCF链接配置文件，自动包含头文件路径。这几个步骤在之前版本的IAR中需要自己手动添加，并且当在PE中重新生成Code时需要重新添加对应的文件； 8. 完成上面步骤之后，需要根据实际情况配置采用的下载/调试器，Project->Options->Debugger->Setup 选择下载Driver，实验中使用的是KL25的FRDM板，所以在PE Macro中选择OpenSDA，点击OK，完成设置； 9. 编译工程，下载Debug； 总结下来，主要完成两个工作：（1）配置使能 Project connection，并导入PE生成的XML文件； （2）配置调试的下载器仿真器；

This hint will demonstrate how to verify ADC conversion rate (with oscilloscope) during testing phase.   Refer to the phenomenon descripted in"Figure 1. Voltage drops at ADC input during sampling process" of AN4373. If too large values is selected for the external RC components, serious voltage disturbances (voltage drops/peaks) at the ADC input (see Figure 1) can be observed. The disturbance at the ADC input in this case results from the basic principle of operation of the sample and hold (S/H) circuit inherent in a SAR ADC. Although we should avoid this happening, but it can be used to measure the ADC conversion rate with oscilloscope during testing phase.   According to the 'Table 30. 16-bit ADC operating conditions' of K64P144M120SF5, we can know that the max ADC conversion rate is 818.330 ksps. Here I create an example by using KDS3.2 with Processor Expert(See the attach file). After select same configuration according to that table, I got almost the same ADC conversion rate. The conversion time meet equation given in Reference Manual too. Now let's measure the ADC conversion rate on FRDM-K64F board with oscilloscope. After connected an external 1.5KΩ resistance, the value of external RC components is big enough to be observed. Below is the waveform observed with oscilloscope, the frequency between voltage drops at ADC input during sampling is about 818 ksps. This test result is consistent with the theoretical calculated value.

For motor control and swich mode power supply application, it is required that the ADC sampling is synchronized with PWM signal. In general, most Kinetis sub-family provides FTM, PDB and ADC, it provides a mechanism for ADC converter is synchronizedc with PWM signal. But the KEA family does not have PDB module, instead, the KEA family provides a simple mechanism which enables PWM signal the FTM module generate can synchronize the ADC converter. The DOC introduces the mechanism, give the register configuration description, code and scope screenshot on how the PWM signal synchronizes the ADC.

Hi team ,      I would like to share an experiment that about the Fast IO - zero wait state access of KL series . Detail please refer to attached file . Best regards, David

   1.  K60 eDMA 16-channel implementation Local memory containing transfer control descriptors for each of the 16 channels 32-byte TCD stored in local memory for each channel    2.  DMA memory to memory performance In the traditional M2M data movement, performance is best expressed as the peak data transfer rates In most implementations, this transfer rate is limited by the speed of the source and destination address spaces.     3.  eDMA peak transfer rate   4. Performance test         With K60 100MHz (TWR-K60D100M), implement internal SRAM-SRAM eDMA data transfer. If  transfer size setting as 32-bit in TCD Transfer Attributes (DMA_TCD_ATTR), there will has one wait state during each read/write. That's why the DMA performance doesn't up to 200MB/s as the manual stated.       We highly recommend setting DMA transfer size to 16-byte at DMA_TCD_ATTR register, it will much increase the DMA performance.(Get 162MB/s transfer rate with TWR-K60D100M board.) 5.  Testing code attached.

Actually the latest FSL USB stack has become part of KSDK , so it is recommended customer design USB application based on KSDK, while there are some old parts like K70, K60F and KL25 are still not supported in KSDK yet, so USB stack ver 4.1.1 is somewhat of help for those who still develop application based on those parts. USB stack ver 4.1.1 supports K70 instead of K60F, but since they are both Kinetis 120MHz parts, so the porting is very easy, here I provide a porting guide for this part. The porting is based on K70 USB examples, either Host or Device. 1. Replace the device header file. Use MK60F12.h instead, which may be extracted from KINETIS_120MHz_SC(Kinetis 120MHz bare metal sample code) , and put this header file in the folder of "C:\Freescale\Freescale USB Stack v4.1.1\Source\Host\source\bsp\P3" for Host or "C:\Freescale\Freescale USB Stack v4.1.1\Source\Device\app\common\kinetis" for device, and modify derivative.h as  below: 2. Macro definition changes in MK60F12.h, MCU_MK60F12 is defined instead of MCU_MK70F12, so in this step we will have to change some code snippet related with MCU_MK70F12. Firstly search MCU_MK70F12 in the project, for example ， in the Host demo USB_MSD project based on IAR, you may do that as below: and you may find some macro like "#ifdef MCU_MK70F12" or "#ifndef MCU_MK70F12", and change them as below: #ifdef MCU_MK70F12 ----> #if (defined MCU_MK60F12) || (defined MCU_MK70F12) #ifndef MCU_MK70F12 ----> #if (!defined MCU_MK60F12) && (!defined MCU_MK70F12) 3. IO driver modification. Since TWR-K70F120 has almost the same hardware as TWR-K60F120, there is no need to change the driver code after replacing the header file, except the serial port driver, referring to USB_MSD demo, the serial driver is in sci_kinetis.c, TWR-K70F120M uses PTE16 and PTE17(UART2) as the console, while TWR-K60F120M use PTE8 and PTE9(UART5) instead, so you have to change the driver as below to make printf work properly. void sci2_init(){ #if (defined MCU_MK60F12) || (defined MCU_MK70F12)     register uint_16 sbr, brfa;     uint_8 temp; #ifdef MCU_MK70F12     /* Enable the UART2_TXD function on PTD3 */     PORTE_PCR16 = PORT_PCR_MUX(0x3); // UART is alt3 function for this pin     /* Enable the UART2_RXD function on PTD2 */     PORTE_PCR17 = PORT_PCR_MUX(0x3); // UART is alt3 function for this pin     /* Enable the clock  */     SIM_SCGC4 |= SIM_SCGC4_UART2_MASK;     /* Make sure that the transmitter and receiver are disabled while we      * change settings.      */     UART_C2_REG(UART2_BASE_PTR) &= ~(UART_C2_TE_MASK | UART_C2_RE_MASK);     /* Configure the UART for 8-bit mode, no parity */     UART_C1_REG(UART2_BASE_PTR) = 0;    /* We need all default settings, so entire register is cleared */     /* Calculate baud settings */     sbr = (uint_16)((SYSCLK*1000)/(UART_BAUDRATE * 16));     /* Save off the current value of the UARTx_BDH except for the SBR field */     temp = UART_BDH_REG(UART2_BASE_PTR) & ~(UART_BDH_SBR(0x1F));     UART_BDH_REG(UART2_BASE_PTR) = temp |  UART_BDH_SBR(((sbr & 0x1F00) >> 8));     UART_BDL_REG(UART2_BASE_PTR) = (uint_8)(sbr & UART_BDL_SBR_MASK);     /* Determine if a fractional divider is needed to get closer to the baud rate */     brfa = (((SYSCLK*32000)/(UART_BAUDRATE * 16)) - (sbr * 32));     /* Save off the current value of the UARTx_C4 register except for the BRFA field */     temp = UART_C4_REG(UART2_BASE_PTR) & ~(UART_C4_BRFA(0x1F));     UART_C4_REG(UART2_BASE_PTR) = temp |  UART_C4_BRFA(brfa);       /* Enable receiver and transmitter */     UART_C2_REG(UART2_BASE_PTR) |= (UART_C2_TE_MASK    | UART_C2_RE_MASK); #else   //MCU_MK60F12         /* Enable the UART2_TXD function on PTE8 */     PORTE_PCR8 = PORT_PCR_MUX(0x3); // UART is alt3 function for this pin     /* Enable the UART2_RXD function on PTE9 */     PORTE_PCR9 = PORT_PCR_MUX(0x3); // UART is alt3 function for this pin                /* Enable the clock  */     SIM_SCGC1 |= SIM_SCGC1_UART5_MASK;     /* Make sure that the transmitter and receiver are disabled while we      * change settings.      */     UART_C2_REG(UART5_BASE_PTR) &= ~(UART_C2_TE_MASK | UART_C2_RE_MASK);     /* Configure the UART for 8-bit mode, no parity */     UART_C1_REG(UART5_BASE_PTR) = 0;    /* We need all default settings, so entire register is cleared */     /* Calculate baud settings */     sbr = (uint_16)((SYSCLK*1000)/(UART_BAUDRATE * 16));     /* Save off the current value of the UARTx_BDH except for the SBR field */     temp = UART_BDH_REG(UART5_BASE_PTR) & ~(UART_BDH_SBR(0x1F));     UART_BDH_REG(UART5_BASE_PTR) = temp |  UART_BDH_SBR(((sbr & 0x1F00) >> 8));     UART_BDL_REG(UART5_BASE_PTR) = (uint_8)(sbr & UART_BDL_SBR_MASK);     /* Determine if a fractional divider is needed to get closer to the baud rate */     brfa = (((SYSCLK*32000)/(UART_BAUDRATE * 16)) - (sbr * 32));     /* Save off the current value of the UARTx_C4 register except for the BRFA field */     temp = UART_C4_REG(UART5_BASE_PTR) & ~(UART_C4_BRFA(0x1F));     UART_C4_REG(UART5_BASE_PTR) = temp |  UART_C4_BRFA(brfa);        /* Enable receiver and transmitter */     UART_C2_REG(UART5_BASE_PTR) |= (UART_C2_TE_MASK    | UART_C2_RE_MASK); #endif        #endif } #ifdef __CC_ARM int sendchar (int ch) #else void TERMIO_PutChar (char ch) #endif { #if (!defined MCU_MK60F12) && (!defined MCU_MK70F12)     #if (defined MCU_MK20D5) || (defined MCU_MK20D7) || (defined MCU_MK40D7)         /* Wait until space is available in the FIFO */         while(!(UART1_S1 & UART_S1_TDRE_MASK)){};                /* Send the character */         UART1_D = (uint_8)ch;       #elif(defined MCU_MK21D5)         while(!(UART2_S1 & UART_S1_TDRE_MASK)){};                /* Send the character */         UART2_D = (uint_8)ch;       #elif(defined MCU_MKL25Z4) || (defined MCU_MKL46Z4)         /* Wait until space is available in the FIFO */         while(!(UART0_S1 & UART_S1_TDRE_MASK)){};        /* Send the character */        UART0_D = (uint_8)ch;       #else         /* Wait until space is available in the FIFO */         while(!(UART3_S1 & UART_S1_TDRE_MASK)){};                /* Send the character */         UART3_D = (uint_8)ch;     #endif   #else #ifdef MCU_MK70F12     /* Wait until space is available in the FIFO */     while(!(UART2_S1 & UART_S1_TDRE_MASK)){};     /* Send the character */     UART2_D = (uint_8)ch; #else      /* Wait until space is available in the FIFO */     while(!(UART5_S1 & UART_S1_TDRE_MASK)){};     /* Send the character */     UART5_D = (uint_8)ch; #endif #endif } 4. Set the correct device type in IDE settings. For IAR, change the device family in view of project options. Now, you can start to run the USB demos on TWR-K60F120M, please note the above steps is ok for USB device stack, but USB Host stack has some code issue , as mentioned in [USB stack ver 4.1.1] a code issue in msd_mfs_generic host demo , so please fix the issue before going further. Hope that helps, Best Regards, Kan

The TWR-KW2x board's OpenSDA is programmed with MSD (Mass Storage Device) application, that's why you see it listed as a disk drive. With that firmware, you can drag/drop .bin and .srec files to the board and that would flash it, but you won't be able to debug. For the boards to support download/debug features, the firmware for the OpenSDA had to be the Debug App ("DEBUG-APP_Pemicro_v108.SDA"). But PEMicro released a new firmware which supports BOTH functionality in the same firmware. You can also find it latest OpenSDA firmware at https://www.pemicro.com/opensda/ For example: Firmware that supports Debug and MSD functionality for TWR-KW24D512: "MSD-DEBUG-TWR-MKW24D512_Pemicro_v114.SDA". You can find attached the document with the instructions to modify the OpenSDA firmware on the TWR boards, basically you have to: 1. Unplug the board 2. Insert a Jumper in J30 to put the device in Bootloader mode 3. Plug in the board (Mini-USB) 4. Device will be enumerated as a "Drive Disk" But now with a "Bootloader" label 5. Drag and Drop the .SDA firmware to the drive (MSD-DEBUG-TWR-MKW24D512_Pemicro_v114.SDA) 6. Unplug the board 7. Remove Jumper 8. Plug in the board (Mini-USB) Now you should see the board being enumerated as "OpenSDA - CDC Serial Port" (allowing you to download/debug) and also listed as a disk drive(allowing you to drag/drop images to the board). Note1: If the "OpenSDA - CDC Serial Port" driver is not recognized, you can locate the driver within the TWR's Disk Drive (MSD) Note2: Jumper has to be in place in J29 for debugging Hope this info is helpful. You can find additional information on www.freescale.com/TWR-KW2x  --> Downloads -> Board Support Package  AND BeeKit Wireless Connectivity Toolkit

Hello Kinetis friends! The launch of new Kinetis devices and development tools called "Kinetis K2" brought some new K22_120 MHz devices to the K22 family portfolio. :smileyinfo: Please notice the name "Kinetis K2" only refers to the Kinetis generation, but it is not related to part number (e.g. K63/K64 are part of K2 generation). Previously existing Kinetis portfolio already had some K22_120 MHz devices, so this  caused confusion regarding the documentation, header files, features, development boards and others, because the part numbers are very similar. I created the next reference table outlining the existing K22_120 MHz parts with their corresponding files and boards. The last column is an overview of the features or peripherals that are either missing or added in each device. :smileyalert: IMPORTANT NOTES:           - I gathered and put together this information as reference, but it is not official. For the most accurate information please visit our webpage www.nxp.com.           - Header files MK22F12.h and MK22FA12.h apply for legacy K22_120 devices. However TWR-K21F120M(A) board has a K21_120 part, so use MK21F12.h or MK21FA12.h instead.      Colleague Carlos Chavez released an Engineering Bulletin (EB811) with good information related to this document:      http://cache.nxp.com/files/microcontrollers/doc/eng_bulletin/EB811.pdf Regards!

我们知道Kinetis L系列的中断向量表中只支持两个外部中断向量（vector_46 and vector_47），而FSL早期推出的的KL系列（包括KL25\KL24、KL15\KL14）只有PORTA和PORTD两个IO口支持中断，不过最新推出的KLx6系列（KL26、KL16和KL46）可以支持PORTA、PORTC和PORTD三个IO口的外部中断，其中PORTC和PORTD这两个IO端口共享同一个中断向量，另外，KL0x系列（包括KL02、KL04和L05）由于外部引脚只有PORTA和PORTB两个IO端口，所以它所支持的外部中断只有PORTA和PORTB。 下图分别为KLx5\KLx4系列（不包括KL05\KL04）、KLx6系列和KL05\KL04\KL02的外部中断向量分配表： KLx5\KLx4: KLx6: KL0x: KLx6的头文件注释： 最后需要注意的是，目前所有官方的demo例程（KLxx_SC）的中断向量表vector.h和MKLxxxx.h文件中关于中断向量的注释仍然是PORTA和PORTD，甚至有一部分例程中中断向量表的注释仍然是M4的注释直接移过来的，容易误导客户编程，这点需要在设计PCB板的时候有所考虑。

KBOOT learning diary Overview      FSL’s already released the KBOOT v1.1.0 in Dec, 2014 and the v1.2.0 will be released in Jun, 2015. KBOOT is an innovation bootloader solution instead of former and it just seems like a platform for quick and easy programming the Kinetis MCUs. KBOOT will make the developers to save the effort for design the bootloader, even it support the developers to customize the bootloader.        KBOOT provides two ways for implementing, ROM bootloader and Flash bootloader, ROM bootloader is only applicable to the Kinetis MCUs which already integrate the ROM and the KBOOT application reside in it. So the ROM bootloader is available during the entire product life cycle.  The opposite side, the Kinetis MCUs without ROM can be programmed through the Flash bootloader. For the Flash bootloader, it runs into RAM and receive the application image, after it program the image into the Flash completely, then it Flash bootloader will go to die, in another word, it will no longer be available again. Table 1 shows supported Kinetis MCUs. Table 1 Support Kinetis Devices        KBOOT’s supported to program the target through the UART, SPI, I2C, USB HID communication and it will also support the MSD Device and MSD HOST mode, Ethernet, etc in future. And developers can use blhost application or GUI tool as the host tool to communicate with the bootloader, then program the application code in flash via the bootloader. Implementing        In these user guides as follow: Getting Started with the Kinetis ROM Bootloader, Getting Started with the Kinetis Flashloader, Kinetis blhost User's Guide, Kinetis Updater User's Guide, you can find a completely procedure to program the application code via bootloader. Exception However I’ve encountered an issue when I tried to use the blhost application to communicate the FRDM-KL03Z (Fig1), it still couldn’t establish a connection, as Fig 2 shows. Fig 1 Fig 2 Workaround       The issue will disappear after choose a lower baud rate when blhost application communicate with the FRDM-KL03Z board after I validated. And the whole procedure to program application code as follow.       1. Establishes the connection        2. Erases the entire flash array       3. Programs the application code       4. Application code runs
