基于51单片机的RTC实时时钟例程，包括源码和芯片手册以及DS1302电路图(51 microcontroller-based RTC real time clock routines, including the source and chip manual and DS1302 circuit diagram)

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.)

关于SHT11与单片机的一些源代码,经验证过,没有错误(SHT11 and SCM on some source code, proven before, no errors)

解压密码754432568，光立方源代码内容详细，有相应原理图绘制(Decompression password 754432568, optical cube source code content is detailed, there are corresponding schematic drawings)

说明：  无线温度控制及监测系统，基于stm32开发(Wireless Temperature Control and Monitoring System)

old gpio interface to other kernel modules don t use in new code, will go away in 2.7 have a look at bttv-gpio.c instead.

说明：  pda project using pda

说明：  STM32实现人脸跟踪，通过舵机控制摄像头跟踪人的脸，顶顶顶顶顶顶顶(STM32 realizes face tracking. The camera is controlled by the steering gear to track people's face)
