这是利用两个红外对管做的速度检测装置，全是我自己写的。-This is done using two infrared tube speed detection device, all I wrote it myself.

stm32c8t6最小系统板，oled显示速度，红外对管检测码盘转速，基本算法控制小车走直线(Stm32c8t6 minimum system board, OLED display speed, infrared tube detection code disc speed, basic algorithm control car to go straight line)
