The quadrature decoder (QDEC) driver includes two layers: the hardware abstraction layer (HAL) and the driver layer (DRV).

The hardware abstraction layer provides basic APIs for accessing the registers of the QEDC. See the API documentation for the QDEC HAL for details.

The driver layer provides APIs on a higher level than the HAL. See the API documentation for the QDEC driver for details.

The QDEC Example provides sample code that you can use to quickly get started.
