STM32 is a family of microcontrollers by STMicroelectronics, a leading manufacturer of semiconductor devices.  These microcontrollers are widely used in various electronic applications due to their versatility and features. Here's a breakdown of what STM32 microcontrollers are and why they're popular:
Microcontroller Basics:
Microcontrollers (MCUs): These are small, self-contained computers on a single integrated circuit (IC). They typically include a central processing unit (CPU), memory (RAM and flash), input/output (I/O) peripherals, and digital-to-analog converters (DACs) or analog-to-digital converters (ADCs) depending on the model.
Applications: MCUs are embedded in various electronic devices to control their functions, from simple tasks like blinking LEDs to complex operations in industrial machines or medical equipment.
