S32k3 FreeRTOS UART RX Callback Information

SL239 — Wed, 27 Apr 2022 20:47:40 GMT

Hello,

I am trying to use one callback function to receive RX events using all 4 UART channels on the S32k3X4EVB-Q257.

I then need to determine which channel the message came in on.

Has anyone done this? Possibly using the void userData pointer parameter?

Or any other way.

I cannot use separate callbacks.

Thanks in advance,

-Sean L

Hi Sean,

I can see in the callback typedef that there's HwInstance parameter, so you should have information about the channel:

Thanks for your reply.

I was able to accomplish this by using the HwInstance, and the Event type.

Thanks!
