Hi,
First of all , I'd like to express huge appreciation that the designs for keep, rampart etc. are shared in the way they are.
I built rampart and it works really well.
One thing I'm not sure about is how external sync is intended to work. I tried putting a PO sync signal on the input, and then connected TX to the Analogue 367 pins with the bytebeats sketch, but it didn't seem to do much. Is there a significance that the sync goes to the TX pin?
There's nothing obvious in the sketch which handles a sync pulse.
Any tips greatly appreciated!!
