Hi,

Is it required to implement rlDeviceMaskHostIrq()/rlDeviceUnMaskHostIrq() callback function if the interrupt trigger is a rising edge trigger?

Thanks !

Hi,

Do you plan to edge trigger the GPIO interrupt?

Thank you

Hi,

We plan to use edge trigger. However, there is a limitation and we can only use it as a rising edge only.

Thanks,

Hello Dominic,

rlDeviceMaskHostIrq()/rlDeviceUnMaskHostIrq() callBacks are provided if Host uses the level trigger to recognize the HostIRQ and using these callbacks it'll mask those to avoid getting multiple interrupt for the same HostIRQ event.

As mmWaveLink expects these two callbacks else rlDevicePowerOn will return an error, so in your case (rising edge) you can provide a dummy/blank function to these callbacks.

Regards,

Jitendra

Thanks, that's exactly what I did but I just want to double check.
