电子温度计，可以准确的测量当前的温度，经过长时间的测量，误差不到1度(Electronic thermometer, you can present an accurate measurement of temperature, after a long period of measurement error less than 1 degree)

使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

交通信号控制,适用于51单片机芯片上，运行环境为visual C(Traffic signal control, suitable for 51 MCU chip, the operating environment for the visual C)

CS5460A芯片源程序，能测量电流、电压以及电能等量。(CS5460A chip source program, which can measure current, voltage and equal power.)

This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:
