基于AVR单片机的电阻测试仪，带有LED数码管显示，内有CVAVR 的C编译器和烧写软件，还有程序流程图和源码电路。(Based on AVR microcontroller resistance tester with LED digital tube display, there CVAVR C-compiler and writing software, as well as program flow chart and source circuits.)

AD8638/AD8639：16V自稳零、轨到轨输出运算放大器(中文版PDF, 728 KB)(AD8638/AD8639: 16V Auto-Zero, Rail-to-Rail Output Operational Amplifier (Chinese edition PDF, 728 KB))

This class checks whether the output is up to date.

代码转换程序之把十六进制数转换为ASCII码(The hexadecimal system transformation is the ASCII code)

CD4051驱动，可使用不同单片机平台，根据文件中的说明可直接在不同平台上使用(CD4051 Deriver C Code)

使用stm32开发板做的pwm输出控制buck电路，反馈使用PID算法，实现闭环控制(The use of STM32 development board to do PWM output control buck circuit, feedback using PID algorithm to achieve closed-loop control)

使用FFMPEG库进行视频解码，然后在一个Static控件上使用SDL2.0进行视频显示，相比SDL1.0,2.0版本支持多窗口同时显示，性能也大幅提升。（demo中未处理音频帧）。本Demo优点：将视频解码和显示分别封装了两个类CFfmpegDecod和CSdlShow，便于学习和理解播放流程。适合学习者使用。(Using the FFMPEG library for video decoding, and then on a Static control on the use of SDL2.0 video display, compared to the SDL1.0,2.0 version supports multi window at the same time, performance is also greatly improved. (demo is not processed for audio frames). The Demo advantages: the video decoding and display are encapsulated in two classes CFfmpegDecod and CSdlShow, easy to learn and understand the playback process. Suitable for learners to use.)
