3.1.6 SPI Accelerometer
The BOOSTXL-UPLSENSE comes with a ultra-low power accelerometer. This sensor uses the serial peripheral interface (SPI) interface to communicate with the Sensor Controller. In the SPI accelerometer example, the device is kept at a steady state. The accelerometer will report to the Sensor Controller with a frequency of 100 Hz. If a change in the accelerometer over a certain threshold is detected, the Sensor Controller will wake up the system CPU and the System CPU will light up one of two LEDs.
