About STM32F103C8 Examples

A collection of example programs for the STM32F103C8 microcontroller (commonly known as Blue Pill). Covers a wide range of peripherals including ADC, DMA, I2C, SPI, USART, PWM, USB (keyboard, mass storage, virtual COM port), timers, external interrupts, power management modes (sleep, stop, standby), watchdog, real-time clock (RTC), bootloader, and various sensors (BMP280, MS5611) and displays (Nokia5110, SSD1331, WG12864A). Also includes motor control examples for BLDC (sensorless and sensored), PMSM, and stepper motors. Written primarily in C with some C++, Makefile, and assembly. Provides a practical, hands-on resource for learning embedded development on the STM32 platform.
