航模用AVR M48开发的无刷电调驱动，参考德国的代码-AVR M48(Model aircraft using the AVR M48 developed brushless ESC drive, refer to the German code-AVR M48)

CAN总线之saj1000与82c250应用源程序，基于c8051f340单片机平台(CAN bus and the 82c250 application saj1000 source, based on single-chip platform c8051f340)

说明：  直流电动机检测程序，用于检测电动机是否正常(DC motor testing procedures for detecting whether the normal motor)

系统平时处于循环接收检测状态，当有按键动作后发送数据 ，对方收到数据后LED闪烁， 任何一方可以发数据也可以收数据。 1． 当检测到按键动作后发送数据，自身LED闪烁 2． 当收到数据后LED闪烁 (Usually in the loop receiver detect state data, send keystrokes LED flashes after receipt of this data, either party can send data can also receive data. 1. When sending data detected keystrokes own LED flashes. LED flashes when data is received)

说明：  小车控制，蓝牙通信 温湿度传感器驱动 pm2.5传感器驱动(Car Control, Bluetooth Communication Temperature and Humidity Sensor Drive PM2.5 Sensor Drive)

利用GPIO控制无源蜂鸣器发声，播放音乐。使用SysTick延时，使用位带操作寻址IO口引脚。(GPIO is used to control the voice of passive buzzer and play music. Use SysTick delay, use bit band operation to address IO pins.)
