Re: Reading signal from AIO with fidelity?

Thank you for this reply, Nicolai. However, you have only shown my how to determine the actual sample period (rounded down to the nearest ms). This does not seem to solve my issue or clarify anything further for me. You have told me the cycle time at which /dev/piControl0 is updated, but not how to ...

I am seeking clarity from everything I've gathered in my couple weeks of working with the Revolution Pi Connect+ and AIO module. Specifically, I have knowledge gaps when it comes to reading an analog signal with fidelity. First, my understanding is that the AIO module is capable of sampling rates mu...

Re: RevPi AIO sampling rate for 8ms in python

Sven, can you point me to some literature as to how the above code ensures equally spaced data in time? Python is far from real-time, so how does the specified cycle loop not have jitter (i.e. the cycle loop executes every 10 ms +/- some random small amount of time). Is there some underlying code th...
