This repository contains the code belonging to the project done in the Seminar Integrated Electronic Systems course at Technische Universität Darmstadt

M20 Screw Project

Overview of the project

This project aims to allow a BLE microcontroller (EFR32BGM from Silicon Labs) to retrieve strain and temperature data from an ADS1220 through SPI. After this, the information is to be transmitted through BLE to a receiving device (namely a computer or RaspberryPi).

Main logic

The behavior of the system is ruled by a Mealy FSM.

BT Profile

The BT profile created contains a single characteristic (representing the sensor in charge of measuring 3 strain sensors and 1 temperature sensor) and 4 descriptors, one per source of data. Each of the descriptors is enabled with notify and read operations.

ADS1220 API

A class has been created to easily interact with the ADS1220.
