stm32g4-lab

This project serves as a simple and practical tutorial for those interested in getting started with STM32 firmware development.

Development Hardware and Software

• Development Board:
  NUCLEO-G474RE

• USB cable
  Type A (male) to Micro B (male)

• IDE:
  STM32CubeIDE 1.19.0

IDE

• You must create a ST account to download the IDE.
• Important: After installation, you need to log in to use the IDE.
  • In version 1.19.0, this is located at:
    Help => STM32Cube updates => Connection to myST
  • Note: The login location may vary between versions, so you may need to locate it manually.
    

Official Documentation

STM32 provides a wide range of official documents for different purposes. In my opinion, the following are the most essential:

MCU – STM32G474RE

• Datasheet

  • Basic introduction to the MCU
  • Block diagram
  • Pin descriptions: Each pin supports only a limited set of functionalities; check this section for mapping.
  • Order information: Understand designations like "RE".

• Reference Manual

  • Comprehensive technical details
  • System architecture and memory map
  • In-depth explanation of each peripheral:
    • Functionality of each register — this is essential reading beyond just using the provided APIs.
    • Register addresses

Development Board – NUCLEO-G474RE

• User Manual

  • Powering the board (multiple configurations supported)
  • The pin of USER Button and USER LED
  • The UART mapped to the virtual COM port
  • Description of onboard LED indicators

• Schematic

  • Full PCB wiring details
  • Understand why certain pins cannot be used for specific peripheral
