I am unable to control pin 83 on the K22 100PQFP chip.
This is PTC13 .
I'm using SDK_2.x_MK22FN512xxx12 version 2.2.0.
The pin mux is configured for
PORT_SetPinMux(PORTC, PIN13_IDX, kPORT_MuxAsGpio);
The same configuration is setup for PTC12 and PTC14 and I'm able to control those pins.
Hi An:
I would suggest you attach the whole project here, so we can see the GPIO configurations and can reproduce your issue on my side.
Regards
Daniel
