Hi,
I'm working on a test for the pulse width measurement, the input is analog signal.
I'm using a while loop, and use nrfx_comp_sample in the loop to get the voltage UP and DOWN result, the V+ is external analog signal, the V- is a fixed voltage(0.2mV) from AIN1, is precision of COMP is not enough to capture it?
Or is there any better way to capture the lowest signal? PPI? but just no idea how to do that with PPI.
Thanks
Hi there, I noticed the Propagation delay of the COMP is 0.1μs, yeah, I'm running the COMP at the high speed mode. But even the Propagation delay is so fast, but still can't manually sample it in the main() to get the voltage smaller then V-(0.2v)? and as I mentioned above, the V+ will have 0.18v at sometimes.
