PCNT - Pulse Counter
Description
Pulse Counter (PCNT) Peripheral API.
This module contains functions to control the PCNT peripheral of Silicon Labs 32-bit MCUs and SoCs. The PCNT decodes incoming pulses. The module has a quadrature mode which may be used to decode the speed and direction of a mechanical shaft.
