Advanced MPR121 tuning These hardware filters affect all 32 cells. Higher values reject more noise but add latency. Defaults: debounce 1/1, FFI 0, SFI 1, ESI 0.

Touch debounce Consecutive touch cycles before press

1 ~6 ms

Release debounce Consecutive release cycles before release

1 ~6 ms

FFI First Filter Iterations · front-end noise averaging

SFI Second Filter Iterations · final smoothing window

ESI Electrode Sample Interval · time between filter samples

Detection cycle: 6 samples × 1 ms = ~6 ms.

FFI averages the first-stage charge measurements. Raise it to suppress high-frequency electrical noise; large values increase scan work.

SFI controls how many second-stage samples form each touch decision. ESI controls the time between those samples. Raising either smooths noisy readings, but directly increases response and debounce time.

Sensitivity; 50 = stock thresholds.

Delta Gate; A threshold filter. If sweat or something else is causing false touches. ie. If the gate is 30 it will not register an input inside the game.

Slider Delay; Artificial delay to the ground slider. 60hz Arcade user 120hz at home recommended delay: 26ms
