PWM-driven matrix keypad driver for ESP-IDF using row pulse-width encoding and MCPWM capture for simultaneous multi-key detection. Supports multiple keys per column with hardware-assisted decoding.
This component detects a double reset (two resets within a short time window) and exposes the result through a small C++ API. A typical use case is to let an end user double-tap reset to enter a special mode (Wi-Fi provisioning, safe mode, configuration portal).
