  2. Configure the microcontroller: Configure the microcontroller settings, such as the clock speed and peripheral settings.
  3. Generate code: Generate code for your microcontroller using the STM32CubeMX code generator.

Step 5: Write and Compile Code

To write and compile code, follow these steps:

  1. Create a new project: Create a new project in your favorite IDE or text editor.
  2. Include libopencm3: Include libopencm3 in your project by adding the following line to your code: #include <libopencm3/stm32/rcc.h>
  3. Write code: Write code for your microcontroller using the libopencm3 APIs.
  4. Compile code: Compile your code using the GCC compiler.
