I want to use the function of lpuart interrupt
The following is the way I set it, but it never enters "LPUART1_RxTx_IRQHandler"
main.c
LPUART1_RxTx_IRQHandler funciton
Pin_mux setting
When I send commands from the PC to the MCU, none of them seem to enter IRQHandler
Hi Zack_huang,
Please refer the lpuart_echo_s32k146 of S32K1xx SDK RTM v4.0.2 Example.
You can check the register value of LPUART1 during debug. Does the LPUART1_STAT[RDRF] be set? Does the signal well connect to the LUPART1_RX PTC6?
Best Regards,
Robin
