Basic application that presents the project scenarios for S32 SDK
The purpose of this demo is to show the user how UART PAL works over FLEXIO_UART or LPUART peripherals. The user can choose whether to use FLEXIO_UART or LPUART (see USE_FLEXIO_UART define from example code). The board sends a welcome message to the console with further instructions. If 'Hello!' string is sent from the console, the board will reply with 'Hello World!'; when any other string is sent from the console, it will be echoed back. Red led(devkit) or led 1(Motherboard) shall be turned on if the communication is done over FLEXIO_UART;similarly the led shall be turned off if the communication is done over LPUART.
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 | S32K-MB or S32K144-MB |
---|---|---|
RED_LED (PTD16) | RGB_RED - wired on the board | |
LED1 (PTC1) | JP50 - jump 50 on motherboard | |
LPUART0 TX (PTB1) | UART_TX - wired on the board | J10.32 - J20.2 |
LPUART0 RX (PTB0) | UART_RX - wired on the board | J10.31 - J20.5 |
FLEXIO_UART RX (PTA1) | J2.10 - J3.2 | J9.32 - J20.5 |
FLEXIO_UART TX (PTA0) | J2.9 - J3.4 | J9.31 - J20.2 |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select uart_pal_echo. 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(uart_pal_echo). 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) 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 |
---|---|
uart_pal_echo_s32k118_debug_flash_jlink | Debug the FLASH configuration using Segger Jlink debuggers |
uart_pal_echo_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.
For this example it is necessary to open a terminal emulator and configure it with:
