Firmware Development for nrf52840 Dongle

The purpose of this project is to develop a firmware for nrf52840 DK and nrf52840 dongle, able to perform the following tasks:

• Connect nrf52840 dongle with mpu9250 (accelerometer)

• Nrf52840 dongle has to be in the sleep mode at the beginning of the cycle;

• Nrf52840 dongle has to be waked up by an external action

• Nrf52840 dongle must read vibration data from 3 axis for 500ms

• Nrf52840 dongle has to calculate the vibration RMS for each axis (the code to calculate RMS will be provided by us)

• Nrf52840 dongle has to send this data to other nrf52840 DK

• Nrf52840 must send this data via UART to computer

• After sending data, nrf52840 dongle must sleep again

All the process it is explained in the attached image:

Taidot: elektroniikka, Mikrocontroller, Arduino, C-ohjelmointi, Sulautetut ohjelmistot
