Detailed Description

Board hardware control, configuraton and miscellaneous functions.

This module contains functions releated to board features. It allows control over power management features, interrupt controller and RGB LEDs.

The BOARD module uses the common I2CSPM driver to communicate with the on-board Power and Interrupt Controller over I ² C. The following board features can be enabled when needed using the BOARD Module:

Environmental sensor group
- RH/Temp (Si7021)
- UV/ALS (Si1133)
- Barometric Pressure (BMP280)
Indoor air quality sensor (CCS811)
Inertial sensor (ICM-20648)
Microphone (SPV1840)
RGB LED boost converter

The BOARD Module also contains functions for controlling the RGB LEDs. The implementation uses one of the TIMER peripherals in PWM mode, with three compare capture channels, one each for red, green and blue.
