STM32 Projects & Tutorials

STM32 microcontrollers are widely used in embedded and industrial systems. This section offers practical tutorials and tested code for STM32F103, STM32F4, and Nucleo boards. Programming is done using STM32CubeIDE with both HAL and LL drivers. Topics include GPIO, UART, ADC, timers, and other core functions—ideal for learners and developers working on real hardware.
