单片机去控制PCF8591T去实现DA功能。 这个代码也要在示波器上才能观测到，DA输出一个正弦波。(Microcontroller to control PCF8591T to achieve DA function. This code also can be observed on an oscilloscope, DA output a sine wave.)

51单片机控制，可远程操控温度和湿度，实时观察与检测(51 MCU control, remote control of temperature and humidity, real-time observation and testing)

SCA100T 通过ATmega128的SPI接口读取两轴角度值(The SCA100T by ATmega128' s SPI interface to read the two-axis angle value)

STM32的U盘存储例程，用keil4编译。(U STM32 disk storage routines, using keil4 compiler.)

说明：  基于stm32f103的超声波测距程序，利用keil编写(Ultrasonic ranging based on STM32F103)

IIC驱动,改变宏定义管脚即可直接使用，非常方便！！！(IIC Driver, Change the macro definition pin can be directly used, very convenient!!!)

AD转换资料，超全大量AD采集电压以及采集电流的方法！(AD conversion data, a large number of ultra-wide voltage and collected current AD acquisition method!)
