    one thing I would like to explore is to use the streamer, I have not found it yet but one last addition to the streamer modes was one that could stream in with a external clock.
    Added for ADC/DAC pins to/from streamer but chip confirmed it works also without activating ADC/DAC.

    Huh, I never knew about that at all. /me goes looking ...

    EDIT: There is this but it doesn't look like a match due to it saying "per clock". Which I understand to mean sysclock:

    Each cog has a 32-bit SCOPE data pipe which is intended to be used with smart pins configured to the 'scope' mode. The SCOPE data pipe continuously aggregates the lower bytes of RDPIN values from a 4-pin block, so that the streamer can record up to four time-aligned 8-bit ADC samples per clock.

    I am 100% sure, even talked with chip about it somewhere around last year. Will ask at the next zoom meeting. Streaming in with external clock from pin to hub or lut.

    Yes, I thought of using the streamer, but (like evanh) I can't see how to do it. If you can provide any details I'll give it a go.

    Only thing I remember it is some ADC mode and you do not activate the ADC pins, just leave them as digital.

    will ask on Wednesday.
