This is the published version of the ADPD2140 driver for STM32 NUCLEO-L432KC microcontroller evaluation board. This firmware allows use of the ADPD2140 light angle sensor and ADPD1080 AFE on-chip gesture recognition engine. Swipe your hand over the sensor board to detect: -up -down -left -right -click
