avrmega16的频率计源码，在2m以内误差为1-3hz，1602显示(avrmega16 the frequency of source, in less than 2m error 1-3hz, 1602 show)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

对于单片机上的一些简单的开发程序和他们的应用(For some simple microcontroller development process and their application)

单片机1260Sc5a 的ad 采集电压，带详细注解，适合初学者哦！(The microcontroller 1260Sc5a ad collection voltage, with detailed notes, suitable for beginners Oh!)

说明：  两脉冲频率平均值计算 两脉冲频率平均值计算 两脉冲频率平均值计算(Two pulse frequency average of the two pulse frequency average of two average pulse frequency)

自带小范围坐标识别，电机控制，语音控制，红外距离探测，电池充电控制，障碍识别，路径规划的功能，代码是基于单片机实现的！(It has the functions of small area coordinate recognition, motor control, voice control, infrared distance detection, battery charging control, obstacle recognition and path planning. The code is based on MCU.)

STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )
