Example application showing the usage of the CRC module
The purpose of this demo application is to show you how to use the Cyclic Redundancy Check of the S32K118 with this SDK.
In this example, The CRC is configured to generate a configurations for CCITT standard following:
The application:
To run the example you will need to have the following items:
The following boards are supported by this application:
The following connections must be done to for this example application to work:
PIN FUNCTION | S32K118EVB-Q064 |
---|---|
RED_LED (PTD16) | RGB_RED - wired on the board |
GREEN_LED (PTD15) | RGB_GREEN - wired on the board |
SW (PTD3) | SW2 - wired on the board |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select crc_checksum_s32k118. Then click on Finish.
The project should now be copied into you current workspace.
First go to Project Explorer View in S32 DS and select the current project(crc_checksum_s32k118). Then go to Project and click on Generate Processor Expert Code
Wait for the code generation to be completed before continuing to the next step.
Select the configuration to be built FLASH (Debug_FLASH) or RAM (Debug_RAM) by left clicking on the downward arrow corresponding to the build button(. Wait for the build action to be completed before continuing to the next step.
Go to Run and select Debug Configurations. There will be four debug configurations for this project:
Configuration Name | Description |
---|---|
crc_checksum_s32k118_debug_ram_jlink | Debug the RAM configuration using Segger Jlink debuggers |
crc_checksum_s32k118_debug_flash_jlink | Debug the FLASH configuration using Segger Jlink debuggers |
crc_checksum_s32k118_debug_ram_pemicro | Debug the RAM configuration using PEMicro debuggers |
crc_checksum_s32k118_debug_flash_pemicro | Debug the FLASH configuration using PEMicro debuggers |
Select the desired debug configuration and click on Launch. Now the perspective will change to the Debug Perspective.
Use the controls to control the program flow.
The CRC module in S32K platform supports both big endian and little endian in source data.
