用单片机实现简单的测电压功能，用七段式数码管显示电压，也可以用上位机实现实时电压-With MCU simple voltage measurement function, with a seven-segment-type digital display voltage, you can also use the PC for real-time voltage

上位机控制程序，原本用于老化嵌入式系统（代号1725），通过上位机下发指令，并显示嵌入式系统的DI、DO等状态。 包括1、通过以太网和嵌入式系统相连接；2、上位机的控制界面；3、其他相关逻辑功能。 -PC control program, originally used for aging embedded systems (code 1725), issued instructions through the PC and display of embedded systems D

这是一个光照采集的上位机程序，这个程序实现了光照数据的接收、存储、数据描画、及实时显示 等功能。-This is a collection of light PC program, this program receiving, storage, data rendering and real-time data display illumination functions.

将模拟音频和视频信号转换为数字信号并压缩后，通过USB口传给上位机，上位机进行图像显示和声音播放。-Analog audio and video signals into digital signals and compressed, to the host computer via the USB port, the host computer for image display and sound playback.
