Neat. For a project I might eventually get back to I was looking at using the M8F controlling an external oscillator. I built a test board[1], but I stopped once I had the GPS working, I can't recall if I even enabled the control of the external oscillator, but I certainly didn't make any attempt to characterize it. Once I get my frequency datalogging issue solved for my other project I might try and see what I get. 1: https://laptop006.livejournal.com/60072.html the DAC, oscillator and supporting components are all in the bottom-left. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
