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 I ² C sensors on the board. 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)
Hall effect sensor (Si7210)
Indoor air quality sensor (CCS811)
Inertial sensor (ICM-20948)
Microphone (ICS-43434)
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.

void BOARD_imuClearIRQ ( void )

Function to clear the IMU sensor interrupt.

Clears the accelerometer and gyroscope GPIO interrupt In the ThunderBoard Sense app example the IMU registers need to be read at quite high rate. Clearing the PIC interrupt register would take too much time. Due to the nature of this example only the IMU interrupt is active and the program can work correctly without identifying the interrupt source and clearing the IT flag in the PIC. If speed is not a limiting factor then always clear the PIC interrupt register by calling the BOARD_picIntClear(BOARD_PIC_REG_INT_CLEAR_IMU); function.

Returns: Returns none
