51单片机dac0809驱动程序，包含整个单片机开发。(51 single dac0809 drivers)

pn532开发的单片机源代码，作为开发NFC的试验用,可读写ISO14443-A/B协议的射频卡和felica以及宝石卡(pn532 developed microcontroller source code, as the development of NFC test, can read and write ISO14443-A/B protocol and RF cards and jewel card felica)

二极管箝位三电平的SVPWM闭环仿真可以运行，使用MATLAB2011a版本，(DCT matlab simulink)

单片机脉冲计数程序，可计算输入脉冲值及误差值，串口写入读出通信。(Single-chip pulse-counting procedure, computable input pulse value and error value, and serial write to read out the communication.)

说明：  led这种裸机的程序，可以先试试手啊哦，还是可以的，欢迎交流学习(led frequently-used vi/vim commands to provide more powerful editing capability for notepad++)

GPRS多路穿透文件，实现多路链接。性能稳定，工厂可以使用(GPRS Multiplex Penetration File)

采用51单片机编写MP3程序，能自由播放音乐，非常有用(MP3 program written using 51 single, free to play music, very useful)

说明：  stm32制作简易信号源，产生方波三角波和正弦波(STM32 makes simple signal source to produce square wave triangle wave and sine wave)

stm32单片机实现对逆变电源的输出波形控制，包含proteus仿真.(stm MCU realizes the output waveform control of inverter power supply, including proteus simulation.)

AT89C2051时钟程序，有注释，开心学习！(AT89C2051Clockprocess)
