待检测pcb板和标准pcb对比，然后对待测pcb腐蚀及膨胀处理，进行缺陷标注显示图像并输出焊盘缺失数，导线缺失数，短路数等。所以源图像均有，并再次测试无误，可以直接运行。(To be detected and the standard pcb board pcb contrast, then treat corrosion test pcb and the expansion process, defect labeling displays images and outputs missing number pad, missing a few wires, short circuit and number. So were the source image, and test again correctly, you can run directly.)

能够快速读取电子海图，还有简单的显示功能(ENC )

用Mega128单片机驱动蜂鸣器，实现音乐的播放功能，程序经过优化，声音比其他版本悦耳。(MCU-driven with Mega128 buzzer to realize the music playback capabilities, the program is optimized, the sound better than any other version of the musical.)

光伏微网逆变器的PCB板图和原理图，可用，测试效率在230w光伏板环境下为91 (Solar Micro Inverter PCB board and schematic diagram, can be used to test the efficiency of photovoltaic panels in the environment 230w 91 )

msp430控制DS18b20温度采集系统，并经过LED显示(msp430 ds18b20 led)

实现蜂鸣器驱动，蜂鸣器应用。非常好的实例。(Buzzer driver, buzzer application. Very good examples.)

STM32F407单片机使用FSMC驱动ILI9488液晶屏(STM32F407 MCU uses FSMC to drive ILI9488 LCD screen)

PSCAD风机（异步机带桨距角控制）经过0.69kV-13.8kV-115kV-345kV三级升压，远距离电缆并入主网模型(PSCAD wind )

说明：  测试环境当前温度，用DS18b20传感器显示在lcd1602上(turnover temperature)

说明：  单片机控制1602液晶反显程序，非常经典是51hei光盘里带的(SCM control program 1602 LCD anti-significant, very classic is a CD-ROM Li Dai' s 51hei)
