S32K146 lpuart interrupt setting

Zack_huang — Wed, 29 Sep 2021 11:06:04 GMT

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
