Detailed Description

NXP MPR121 capacitive-touch codec - implementation. See mpr121.h.

The bring-up register values are the NXP AN3944 / reference defaults (rising/falling/touched filter constants, CONFIG1 0x10, CONFIG2 0x20), with per-electrode touch/release thresholds and an electrode-config (ECR) that enables the electrodes with baseline tracking.
