Hi,

see attached a port of ADC SW trigger example from https://community.nxp.com/t5/S32K-Knowledge-Base/RTD400-LLD-K344-ADC-SW-HW-trigger/ta-p/1966179
Ported to S32DS3.6 with RTD600. Example reads XS32K31XEVB-Q100's POT (ADC1 channel P7, PTA15) and display result on UART0

Hope it helps.

BR, Petr

but i don't understand one thing how printf function is transmitting data? don't we need to call Lpuart_Uart_Ip_SyncSend API for transmitting data to serial terminal?

Hi,

I reuse retarget.c/h files from original project. You need to modify them based on target used. The _write function is defined which calls Lpuart_Uart_Ip_SyncSend.

_write function is called by bottom level of printf routine within C library.

ok got it...but rather than creating those retarget files and all, i can simply transfer data using UART API's in main source file?
