Example application showing a subset of the eDMA functionalities
The purpose of this driver example is to show you how to use the eDMA in the following transfer scenarios for the S32K144 MCU with the S32 SDK API.
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 | S32K144EVB-Q100 | S32K144-MB |
---|---|---|
LPUART1 TX (PTC7) | UART_TX - wired on the board | J11.26 - J20.2 |
LPUART1 RX (PTC6) | UART_RX - wired on the board | J11.25 - J20.5 |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select edma_transfer. 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(edma_transfer). 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 |
---|---|
edma_transfer Debug_RAM Jlink | Debug the RAM configuration using Segger Jlink debuggers |
edma_transfer Debug_FLASH Jlink | Debug the FLASH configuration using Segger Jlink debuggers |
edma_transfer Debug_RAM PEMicro | Debug the RAM configuration using PEMicro debuggers |
edma_transfer 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.
For this example it is necessary to open a terminal emulator and configure it with:
