Example application that will show the usage of the Watchdog
The purpose of this driver application is to show the user how to use the WDG PAL from the S32K118 using the S32 SDK API.
The example uses the SysTick timer from the ARM core to refresh the WDG PAL counter for 30 times. LED0 will toggle when WDG PAL counter is refreshed. After this the WDG PAL counter will expire, WDG PAL interrupt will happen and turn off LED0, LED1. Then the CPU will be reset. If the FLASH configuration will be used, then the program will use the Reset Control Module to detect if the reset was caused by the Watchdog and will stop the execution of the program and turn on LED0, LED1.
The 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 | S32K118-MB |
---|---|---|
LED0 (PTD16) | RGB_RED - wired on the boards | J12.17 - J11.31 |
LED1 (PTD15) | RGB_GREEN - wired on the board | J12.16 - J11.30 |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select wdg_pal_interrupt_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(wdg_pal_interrupt_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 |
---|---|
wdg_pal_interrupt_s32k118_debug_flash_jlink | Debug the FLASH configuration using Segger Jlink debuggers |
wdg_pal_interrupt_s32k118_debug_flash_pemicro | Debug the FLASH configuration using PEMicro debuggers |
Selg_palt 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.
