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.)

基于atmega16的步进电机驱动程序，实现正反转及调速等功能。(Based atmega16 stepper motor driver, and achieve positive and speed functions.)
