Digitalpotentiometer

基于51的C语言频率计，内涵仿真图，以实现空能(Based on 51 C-language frequency meter, meaning simulation diagram, in order to achieve air can)

基于STC89C52写的蜂鸣器唱歌程序，可以控制开发板上的蜂鸣器唱歌，适合初学者(Based on the STC89C52 write buzzer singing procedures, can control the development board of the buzzer singing, suitable for beginners)

at89c2051利用74ls164 驱动 共阳极数码管(74ls164 driver to use a total of at89c2051 digital tube anode)

利用stm32上自带的ad和da进行模数和数模转换实验(Use the built-in ad and da stm32 analog to digital and digital to analog conversion experiments)

STM32 SPI程序 感觉还不错 大家可以试试看(STM32 SPI program I feel pretty good we can give it a try)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

基于TI公司的msp430g2553单片机的lcd显示程序，好用(Based on TI company s msp430g2553 MCU LCD display program, absolutely easy to use)

红外的收发测试。。通过2路红外发射，顺序接收，检测收发功能是否正常(Infrared transceiver test. . 2-way infrared transmitter, received out of sequence detection transceiver function is normal)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)
