Analysis of Oscillator Phase-Noise Effects on Self-Interference Cancellation in Full-Duplex OFDM Radio Transceivers

基于STM32的信号发生器（定时器控制），频率 占空比 峰峰值可调，输出最大频率30k (STM32-based signal generator (timer control), the frequency duty cycle peak and peak adjustable, the maximum output frequency of 30k)

说明：  使用stm32f407单片机的CAN通信控制驱动电机，并且该程序可以通过红外遥控(CAN communication with stm32f407 MCU is used to control the driving motor, and the program can be controlled by infrared remote control.)

改写四号中断的 自己编的，，，，，，求过啊！！！一个很简单的小程序(Rewrite the fourth interruption of their series,,,,,, begged ah! ! ! A very simple little program)

C51通过SL811读写U盘完整例程。包含创建目录、创建文件等。(Example for reading and writing U-Disk through SL811 USB host controller.)

利用51单片机结合超声波模块，编写的测距触发系统，程序可移植性好，具有人机界面，选用市售4脚传感器结合51机就可模拟，硬件简单。(The obstacle detection unit 51)

通过单片机输入程序来对步进电机进行控制，以此实现一定功能。(Stepping motor single chip microcomputer)

基于51单片机的超声波测距模块使用，使用HC-SR04模块，定时器测量回波长度(Ultrasound Ranging Module Based on 51 Single Chip Microcomputer)

说明：  004---基于stm32电压表设计(数码管显示)(Based on STM32 voltmeter design (digital tube display)
