       This routine implements all four different mask setting methods.Users can refer to these routines to implement some application scenarios.Please note that this routine is for reference only.When posting this routine, I only did some limited tests, and I don't make sure that there are no problems. If you find it, please leave a message and I will revise it in time.       When the program was flashed into the S32K142EVB, the Blue Led will toggles every 500ms, this Led shows that the program is running on well condictions. If a message was received by S32K142EVB from external CAN bus, the Green Led will toggle,at the same time, the S32K142EVB will sent a message to CAN Bus which have the same data with the message received,and the ID is 0x02.At the last,the Red Led will toggle when a CAN error is occurd.   1.FlexCAN Mask Setting Overview          S32K1XX FlexCAN support  Frame mask function ,as you can see the FlexCAN mask can be set to Global Mask or Individual Mask,and user can choose to use FIFO or MB to receive message,but only MB can be used for sending messages.and one more thing you should be care is that the FIFO can not be used for CAN FD,this is because the FIFO data filed only support 8 bit datafiled.           If you use MB14 or MB15, have to set the mask of these tow MBs separately，and you can take a look at the two functions in the below. ->FLEXCAN_DRV_SetRxMb14Mask();  ->FLEXCAN_DRV_SetRxMb15Mask();   2.Hardware Needs. 1.S32k142EVB,(or own made board which can support CAN communications.) 2.CAN TOOL's which used for send or receive messages from CAN Bus on your computer.   If you don't have such tools ,you can use another board which can replace the CAN tools to send or receive CAN messages. 3.S32K142EVB should be powered by external 12V DC, and don't forget to connect the J107 to 1-2.   3.Software Needs. 1.This demo build on S32 Design Studio for ARM V2.2  2.The SDK version is SDK_S32K1XX_15   4.FlexCAN_RX_MB_Mask_Setting 4.1.Set the Mask Type to Global Mask Type.      In this case, we can only receive the messages which ID from 0x300~0x37F and 0x400~0x47F.      If you try to sent the messages with other ID's, the S32K142EVB will not have any reponse!  4.2.Set the Mask Type to Individual Mask Type.      In this routine,we can only receive frames with IDs in the range of 0x400~0x47F. 5.FlexCAN_RX_FIFO_Mask_Setting 5.1.Set the Mask Type to Global Mask Type.      In this routine,we can only receive frames with IDs in the range of 0x10~0x17, 0x20~0x27,0x30~0x37,0x40~0x47, 0x50~0x57,0x60~0x67,0x70~0x77,0x80~0x87. 5.2.Set the Mask Type to Individual Mask Type.      In this routine, we can only receive frames with IDs in the range of 0x10~0x17,0x20~0x27,0x30~0x37,0x40~0x47, 0x50~0x57,0x60~0x67,0x70~0x77,0x80~0x87.   End       If you need to use CAN FD, please note that FIFO cannot be used. Regarding FIFO, it has three filtering formats, you can refer to the following chapters in the data sheet for details. S32K-RM Rev 13.

Question As we know, the TPPSDK supports S32K144 MCU and various Kinetis MCUs to initialize GD3000 in NXP MC solutions. Because of the release of S32K3 and related SW RTD, it’s necessary to expand the capability of TPPSDK to support S32K3 MC based RTD LLD driver or MCAL driver. Unfortunately, the AA team will not maintain the TPPSDK anymore.  How could we configure the GD3000 chip for S32K3 platform?   Answer I took some time to finish this work. Here I'd like to share you the The Expanded TPPSDK Based on S32K3 RTD that is suitable for S32K3 MC application. You can find the Application Note, the source code of new TPPSDK (GD3000 driver), two examples in the attachment. I hope these materials can help you get start with the expanded TPPSDK on S32K3.

           The hardware of this routine is based on S32K142EVB, the IDE is S32_Design_Studio for ARM 2018.R1, SDK version is S32K1xx_RTM_3.0.0, PTB12 is used to simulate Hall pulse output,PTC12 and PTC13 are buttons to change the flip frequency of PTB12 port, and PTB13 is used as the input capture port. When using the demo program in this article, you need to connect PTB12 and PTB13 ports.   Here we assume that we are using a brushed DC motor!   1.The Hall sensor       The Hall sensor is a magnetic induction sensor. The magnetic ring and the Hall element form an induction combination. The magnetic ring rotates with the rotor. The Hall induction magnetic ring rotates with the rotor. , 3-pole pairs, 4-pole pairs, etc., each pair of poles is divided into two levels of N.S. A pair of magnetic poles outputs one pulse signal, and multiple magnetic poles output multiple pulse signals. The number of magnetic pole stages determines the number of pulse signals. , the higher the accuracy.   Hall sensor 2.The relationship between the motor magnetic ring series and the output Hall waveform 5 pole pairs 3.Determination of motor rotation direction         The direction of the motor is judged by the phase difference of the two Hall signals. As shown in the figure below, the phase of Sensor A is ahead of Sensor B, so it can be considered that the current rotation direction of the motor is clockwise.   4.Calculation of motor speed         The speed of the motor can be calculated by the pulse width of the pulse, and the number of revolutions of the motor can be calculated by the number of pulses. Assuming that the Hall magnetic ring of the motor has 5 pairs of poles, it means that there are five pulses in one revolution of the motor, and the speed of the motor = 60 / (t1 * 5) rev/min. The number of pulses can be obtained by the edge capture function of the FTM. Motor speed and stroke         Assuming that the clock of the FTM is 2MHz, then it takes 1/2000000 seconds for the counter to add 1. Since the unit of the motor speed is rpm, the calculation formula of the motor speed is : -> Motor Speed = 60 / (5 * a* (1 / 2000000))         In this formula, '5' is the number of pole pairs of the magnetic ring, and 'a' is the difference of the counter corresponding to the falling edge of two consecutive pules.         Let’s do a test, the square wave in the below figure is the outputs of PTB12, and the output pulse period is 32.1ms. Then the time required for the motor to rotate once should be:32.1ms *5 = 160.5ms, then the speed of the motor should be: 60 * 1000 / 160.5 = 373.83rpm.   PTB2 output square wave          The below picture is directly obtained by the debugger. It can be seen that the speed of the motor at this time is 373, which is not much different from the value measured by the oscilloscope, which is 373.83. This is because I did not use the floating-point calculation result in the program. In summary, we use the input capture function of the FTM module completes the calculation of the motor speed.   debuger monitor results 5.How to calculate the direction of rotation of the motor         Above we calculated the speed of the motor, but did not make judgement on the direction of the rotation of the motor. As mentioned above, the rotation direction of the motor is judged by the phase difference of the two Hall pulse waveforms. Usually, we think of using the timestamp to judge the current state of the phase, so we will enable the two input captures, and then calculate the two Halls timestamp of the falling edge of the pulse.         In fact, there is a simpler method, it only needs to read the high and low state of the other Hall pulse level when the falling edge of one hall pulse is interrupted. In short, we only need to enable one input capture, and the other to be used as a GPIO port.

Some customers inquire about the FreeMASTER JumpStart Project mentioned in the Get Started with the S32K1xxEVB. So here to talk about the problems you may encounter and how to solve them. Where to download FreeMASTER JumpStart Project Customers may not find where to download FreeMASTER JumpStart Project at the moment. It should be downloaded from the Embedded Software under Design Resources of the development board. But the download link of S32K142EVB \ S32K144EVB \ S32K146EVB is missing. We can search the keywords “* JumpStart” at www.nxp.com download embedded application software and PC host application software that you need. Which version of S32 Design Studio should be used The readme file will tell us which version of S32 Design Studio the project was created. For example: the readme in the S32K144_EVB_JumpStart_Firmware package shows that the project for S32K14x EVB JumpStart SW was created in S32 Design Studio for ARM v2.0. Which version of SDK should be used You may get the Validation of S32K144_EVB_JumpStart_Firmware Kinetis SDK project when import the project : The project S32K144_EVB_JumpStart_Firmware was created for Kinetis SDK SDK_S32K14x_08 which is not installed in this product (repository SDK_S32K14x_08 not found).  The chapter Version Tracking of S32SDK_for_S32K1xx_RTM_3.0.3_ReleaseNotes shows that the SDK_S32K14x_08 means EAR 0.8.5. By default only S32 SDK EAR 0.8.4 is installed in S32DS for ARM 2.0, so we need to update the S32 Design Studio for Arm® v2.0 Update 2 – S32 SDK 0.8.5 EAR & MQX by refer S32 Design Studio for Arm v2.0 - Update 2 available Incorrect UART baud rate setting The baud rate selected for LPUART in Processor Expert is 600 by default, which does not match the description in the readme file. 600 is not in the FreeMASTER serial port baud rate support list, so let us reconfigure the baud rate to 115200 and then click Generate Processor Expert Code. When connect S32K144EVB with FreeMASTER by UART, you can see that the Baud rate 300 is not in the support list. This is the reason why using the default configuration of S32K144_EVB_JumpStart_Firmware is not able to connect with FreeMASTER.       

Some customers inquire how to use FreeMASTER with S32K3. But there is no exists example projects which demonstrate usage of the FreeMASTER serial communication driver in S32K3 Real Time Drivers at the moment. So this article will introduce how to use FreeMaster SDKs in S32K3 RTD 0.9.0. Download S32DS \ S32K3 Development Package \ RTD (SDK) \ FreeMASTER Driver Login your account on NXP website, and download the S32K3 Standard software from TOOLS &SOFTWARE of S32K3 webpage. If you have already installed the S32DS3.4 \ S32K3 Development Package 3.4.0 \ RTD 0.9.0, then you can skip the following part and start directly from 4.Install FreeMASTER Driver 3.0 for S32K3 Install S32K3 Development Package 3.4.0 After install the S32 Design Studio v3.4, we should install S32K3 Development Package 3.4.0(SW32K3_S32DS_3.4.0_D2012.zip): go to menu "Help" -> "Install New Software" and click on "Add..." button Here we uncheck S32 Design Studio S32K3 SDK (RTD S32K3 0.8.1), because we will install the newer version S32K3 RTD 0.9.0 later. Install S32K3 Real Time Drivers Version 0.9.0 S32K3 Real Time Drivers Version 0.9.0 can be installed by refer the Offline Package Installation Setup of S32DS Extensions & Updates: Explanation and How To Use. Install FreeMASTER Driver 3.0 for S32K3 Attach FreeMASTER_S32K3 to S32K344_UART_Printf_Sample_090_34 The reason for choosing the S32K344_UART_Printf_Sample_090_34 project to demonstrate the combination of FreeMaster SDKs is that the project has already configured the LPUART of the S32K3X4EVB-Q257 development board. Select LPUART peripheral as host communication Through the description in the Requirements and Release Description chapter of FreeMASTER Driver Release Notes(FMSTRS32K3RN), we can see that currently only UART interface is supported. The S32K3 FreeMASTER 3.0 version 1.0.0 only support NXP GCC 6.3 or 9.2 for ARM at the moment, but the latest S32K3 Real Time Drivers Version 1.0.0 is based on NXP GCC 10.2.0. This is the reason why RTD 0.9.0 is selected in this article.  The README.txt also shows that: Current package provides FreeMASTER Communication Driver support for S32K344 over LPUART module   LPUART13 is selected in this project for S32K3X4EVB-Q257, so we need to define the base address for FreeMASTER: #define FMSTR_LPUART_BASE           0x404A0000 Modify the main function according to the README.txt: Connect FreeMASTER3.1 to S32K3X4EVB-Q257 board Here we can see that the FreeMASTER3.1 is connected to S32K3X4EVB-Q257 board.

Hi,      The draft time gap, from power-on to clock output of S32K14x, is as below.    You can take a reference. Cheers! Oliver

Often we need to implement a SENT receiver in order to read the information sent by some sensors. It is useful to have the possibility of transmitting different message patterns in order to test your implementation. With this project you can transmit via a computer terminal a group of messages (up to 64). The project runs on a S32K144 EVB board, the output signal goes through J206 pin.

Example of usage of AIPS-lite, Protects the access to GPIO port. This example can be used with UART terminal, 115200 bps. The interface menu shows like this: AIPS example has started Please press 0 + enter to set red LED in GPIO port Please press 1 + enter to set red LED in GPIO port Please press 2: GPIO peripheral will only accept accesses from trusted master, M0 (Core) is set as untrusted when a write access, AIPS cannot longer be modified from core and a reset will occur in the next GPIO access Please press 3: GPIO access is write protected, any write access to GPIO will produce a hard fault

Hello,      NXP does a big change on document structure.     Generally, you can find pin assignment table, interrupt mapping and memory map table in RM. But now, these information change to Excel files and attached in RM.   For example on S32K.    You will find the words in RM, like 'For reset values per port, see IO Signal Description Input Multiplexing sheet(s) attached to the Reference Manual.'    Then, please go to attachment tab of your PDF file viewer, like Adobe Acrobat Reader DC.     These steps are also fit for MPC57xx , S32R family. Cheers! Oliver

Hi,     If you try to compile the sample project within S32K14X_MCAL4_2_RTM_1_0_0, you should take care of the command if you use Linaro.    After you set the environment of compiling and run the command under command window, you should enter     "launch.bat MODE=USER TOOLCHAIN=linaro"    NOT    "launch.bat MODE=USER TOOLCHAIN=LINARO"      The command is case sensitivity.   Hope you can compile the project successfully.  Cheers! Oliver
