This project is a small example of how to use STM32CubeF4's HAL library with the Nucleo STM32F411 board on Linux.

The program in src/main.c is quite simple;

• The clock system is configured to run at 100 MHz from the internal RC oscillator
• GPIOA Pin 5 is set up as output (pull-up) and toggled in the main loop
• UART is started (115200, 8N1) and prints a message at every iteration in the main loop
