How many samples per sec?

Hey, cool little build you have here. I was wondering if you could tell about the performance specs of your bit sequencer?

I don't have the tools to measure the max sample rate, but at least it handles the ~45kHz signal of that power meter w/o any losses. This is an interrupt based sampler (posedge/negedge) so it will be a quite a bit slower than a bitbanging sampler, but at the same time i imagine that it will be more accurate.

I tried to do this interrupt based sampling on an arduino, but the non-arm based arduinos i have could not keep up. Only my Due could sample the Dial (~40kHz), but that's a too big and expensive board for this purpose.
