SAADC Multiple Channel Sampling and Reset with PPI

[Jeffrey Haynes]

I have a situation where I need to sample from multiple channels using SAADC on a timer (similar to maximum performance example).  However, the added catch is that at the end I want to use a timer to reset an external circuit.  I have it somewhat working but I'm currently using the RESULTDONE event to trigger the reset.  I've noticed that event gets fired multiple times, once for each channel.  The documentation is slightly vague on this point but it looks like that is expected behavior.  Is there an event I can use to tell me when ALL channels have finished?

Have you tried using EVENTS_END instead?

// Enable interrupt for buffer full
NRF_SAADC_NS->INTENSET = SAADC_INTENSET_END_Set << SAADC_INTENSET_END_Pos;
NRF_SAADC_NS->INTEN |= SAADC_INTEN_END_Enabled << SAADC_INTEN_END_Pos;
NRF_SAADC_NS->EVENTS_END = 0;

NVIC_EnableIRQ( SAADC_IRQn );
