Learn STM32 programming from scratch in this comprehensive tutorial for beginners. Start by creating a new project in STM32 CubeIDE, then explore STM32 chip configuration, including GPIO pins and clock settings. Understand the project tree structure and essential files before diving into GPIO control and delay functions. Upgrade your ST-LINK and familiarize yourself with the STLINK STM32 debugger/programmer. Build and run your code, then advance to more complex topics such as interrupt handling and UART communication with a PC. Follow along step-by-step to gain practical experience in STM32 microcontroller programming.
