Tod Kurt (todbot)Okay! I got my new “picotouch_grid” controller to be MUCH more responsive by using the #RaspberryPiPico’s PIO blocks to do touch sensing on the much higher-capacitance rows. It’s playable now! Columns are still using #CircuitPython’s wonderful “touchio” library #rp2040 #MIDIController #PicoTouch
If anyone's interested in the #RaspberryPiPico PIO code in #CircuitPython for capsense: https://github.com/todbot/picotouch/blob/main/circuitpython/picotouch_grid/picotouch_grid/touchpio.py
It's pretty much a drop-in replacement for "touchio" except will operate up to 8x faster on large high-capacitance pads.
