Code for Technion Formula car sensors reader
Dependencies: mbed Buffer FATFileSystem
Fork of SX1272PingPong by
This is code is part of a Technion course project in advanced IoT, implementing a device to read and transmit sensors data from a Formula racing car built by students at Technion - Israel Institute of Technology.
How to install
- Create an account on Mbed: https://os.mbed.com/account/signup/
- Import project into Compiler
- In the Program Workspace select "Formula_Nucleo_Reader"
- Select a Platform like so:
- Click button at top-left
- Add Board
- Search "NUCLEO F103RB" and then "Add to your Mbed Compiler"
- Finally click "Compile", if the build was successful, the binary would download automatically
- To install it on device simply plug it in to a PC, open device drive and drag then drop binary file in it
