Abstract The STM32 family of 32-bit ARM Cortex-M microcontrollers from STMicroelectronics has become a dominant platform in embedded systems due to its performance, power efficiency, and extensive peripheral set. This paper provides a complete overview of programming STM32 devices, covering development environments, hardware abstraction layers, low-level register programming, and practical examples. We compare major toolchains (STM32CubeIDE, Keil MDK, IAR EWARM), explain the role of the Hardware Abstraction Layer (HAL) and Low-Layer (LL) APIs, and demonstrate basic peripheral control (GPIO, timers, USART). The paper concludes with best practices for debugging and optimization.
