s32k312 gpio detecting the edge

[fengba_360]

Hello, I have a small request for consultation. I would like to trigger an event by detecting the rising edge or falling edge of a pin, for example, setting a flag to 1 when a rising edge is detected and setting it to 0 when a falling edge is detected. I have reviewed relevant materials and found that this can be achieved through the IP-layer component siul2_icu configuration. However, when using dual-edge detection, how can I determine whether it was triggered by a rising edge or a falling edge? Please guide me on this. Thank you!

Hi

I don't see any flag in the related register to distinguish between rising and falling edges, so I'm afraid you need to read the current voltage of the pin in the callback to make a judgment.

Best Regards,
Robin
