STEP 1: Preparing Your STM32F412 for CircuitPython 

https://circuitpython.org/board/stm32f412zg_discovery/

Installing CircuitPython:

- Download the CircuitPython firmware for STM32F412 from  https://circuitpython.org/board/stm32f412zg_discovery/
- Download the STM32 ST-LINK Utility from  https://www.st.com/en/development-tools/stsw-link004.html
- Use the STM32 ST-LINK Utility to flash the CircuitPython firmware onto the STM32F412 board.

Verifying the Connection:
After flashing the firmware, the connection will be verified, and you will find the "CIRCUITPY" drive (G:), indicating the process is complete.

STEP 2: Getting Started with CircuitPython on STM32F412  


Writing Your First Code in CircuitPython: 
- Guide on creating a code.py file in the CIRCUITPY drive.  
- Simple code example, such as blinking an LED or displaying a message on the Serial Monitor.  
- How to run the code and check the results.

Using CircuitPython Libraries on STM32F412: 
- Introduce useful libraries, such as Adafruit Blinka (which enables CircuitPython support on non-Adafruit boards) and sensor libraries.  
- Explain how to install libraries by copying the library files to the CIRCUITPY drive.

STEP 3: Example Projects

Simple Example Projects:
- LED Blink: Control an LED on the STM32F412 board to blink.
