RE: How to use two ADC parallely with interrupts? Should I use; RTC, Timer or PPI for the same? How to add timestamps for the parallel ADC readings.

I am a beginner in Nordic. To learn; I was trying to combine serial protocols with ADC and it seems to be working fine without any errors. But I failed to add time stamps and create interrupts for ADC readings. Thank you for guiding me to the documents and clearing my doubts is mutliple ADC readings. i understood that, the ADC readings are virtually simultaneous; pseudo- simultaneous. So, I hope i will be able to create interrups and add timestamps to the acquired data. Thank you for your support.

Is that just a beginner with Nordic, or a beginner with microcontrollers in general?

Or a beginner with any form of programming?

For Nordic, start here:

Have you looked at the nRF52832 Prodcut Specification?

It shows you that there is only one ADC; so you cannot read multiple source simultaneously - it will always have to do them sequentially.

The ADC example in the SDK illustrates reading several channels.

How would that help?
