I seem to be having trouble getting a digital signal to trigger any kind of acquisition.
analogue works fine though.
I have an IIC bus with digital probes on it, and I've put analogue probe A on SDA to trigger it for the moment.
But no matter what the settings digital trigger settings in PicoScope (6.6.18) I can't trigger any sampling.
I'm trying to trigger on a falling edge of D0
Am I doing something dumb? (this is my first day with the scope)
