This program recieves and echoes back characters from a host computer running a serial terminal program. You will need a ftdi serial to usb converter, and a serial terminal program installed. I personally like picocom, but any serial terminal program should work.
- GNU Make
- GNU ARM Toolchain
- St-Link Flash Utility
- STM32F407G-DISC1 Development Board
- FTDI serial to usb converter
- picocom
Make sure your discovery board is plugged into your computer, and that you have the required tools installed. Then use your shell to clone the git repository and compile/flash your board.
git clone https://github.com/kolazojar/echo.git
cd echo
make flash
picocom -b 9600 -l -r path/to/ftdi
