STM32 LED Control: From Library Functions to Register-Level Programming
This article demonstrates basic STM32 GPIO control by blinking an onboard LED using both the Standard Peripheral Library and direct register manipulation. The target hardware uses the PC13 pin to drive the LED: a low output turns the LED on, a high output turns it off. All code is developed on an STM32F103 minimum system board.
