This project is produced based on the "100 Getting Started with STM32" video and learning tutorials. Some details and pin definitions may be different. Please refer to the actual situation. Please see the attachment for the relevant code.

In the process of learning STM32, I came into contact with many high-quality tutorials, and the 100-step tutorial for getting started with Yangtao No. 1 development board STM 32 F103C8T6 by Teacher Du Yang felt more suitable for novices to get started, but the price was slightly higher, so I created this project for learning.

The PCB integrates LED, 8-bit digital tube, relay, button*4, wake-up button, smoke sensor, infrared sensor (not verified), four-way joystick, buzzer, 0.96OLED, encoder and other functions.
