数码相框（一个简单的数码相框程序，有I2S，LED,LCD，按键等等）(Digital Photo Frame)

基于单片机的DDS信号发生器，可产生正弦曲线和三角波形(DDS signal generator based on MCU, can generate sinusoidal and triangular waveform)

智能人体感应自动门程序，基于51单片机，主要应用于人员流动频繁的场所。(Intelligent human sensing automatic door program, based on 51 single, frequent staff turnover is mainly used in places.)

说明：  CPU正在执行一项任务A，然后突然停止任务A去执行任务B，执行完任务B再回来继续执行任务A的过程。(CPU is performing A task. A, then suddenly stop tasks to perform A task B, perform the task B come back again continue to perform the task A process.)

基于STM32F103R8的PID算法例程，PWM输出控制信号，ADC输入反馈信号，形成闭环控制，完整工程源码。(PID algorithm based STM32F103R8 routines, complete engineering source, PWM output control signal, ADC input feedback signal to form a closed-loop control.)

使用MDK写的STM32F4的485通信程序，不使用延迟，解决了因485控制端翻转过快而导致的数据发送不完全的情况(The MDK write the STM32F4 in 485 communications program, do not use the delay to resolve the 485 control terminal flip too fast data transmission is not completely)

波形发生器，无线接收，机械手，马达速度控制，计时器等例程，初学者的好帮手(Waveform generator, wireless receiver, robot, motor speed control, timer routines, good helper for beginners)

说明：  实现stm32f429 单片机的CAN 双向通信，CAN接收，与发送(stm32f429 can transmit ,send data and receive data)

MT-safety ensured by the containing loader.
