Cool, low budget hack requiring almost no additional hardware! The author states that "the signal is too strong for our input and goes off-scale, making it almost impossible to reliably detect pedal press/release events". Since the two waveforms are visually quite distinct, it is probably possible to correlate the incoming signal with reference on and off waveforms to detect a state change reliably without using hand-crafted heuristics.
- Rogach 11y agoYes, that's what I tried - but there was a case when next press or release happens while signal is already off-scale from previous event, and I failed to find any sane way to solve that case. Also, the scale on the images is 500ms per one red square, so you can see that waveforms extend over hundreds of milliseconds - thus there will be unbearable latency with that approach.
