LESENSE - Low Energy Sensor

Description

Low Energy Sensor (LESENSE) Peripheral API.

This module contains functions to control the LESENSE peripheral of Silicon Labs 32-bit MCUs and SoCs. LESENSE is a low-energy sensor interface capable of autonomously collecting and processing data from multiple sensors even when in EM2.
