17_LCD1602基本显示程序

说明：  通过计算机25针并口读写SPI总线Flash存储器(25-pin through the computer parallel port read and write SPI bus Flash memory)

说明：  avr单片机，给电压通过单片机片内ad转换给到1602显示。里面有电路图和程序(AVR single-chip microcomputer, the voltage is converted to 1602 display through ad in single-chip microcomputer)

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.)

pca 用于定时器功能 pca可用于捕捉，定时，pwm输出等功能(pca pca can be used to capture, timing, pwm output for timer function)

AT89C51+液晶显示屏，按输入字符输出相应的显示，源代码为C语言编写，希望对大家有帮助。(The LCD of AT89C51+ screen display output according to the input character, the source code is written in C language, we hope to help.)

说明：  100% 可以运行的温湿度显示软件，数据保存在数据库之间的通信 串口通信(100% operational temperature and humidity display software, data stored in the database communication serial port)

单片机串口通信的应用，通过串口，我们的个人电脑和单片机系统进行通信。 个人电脑作为上位机，向下位机单片机系统发送十六进制或者ASCLL码，单片机 系统接收后，用LED显示接收到的数据和向上位机发回原样数据。(Single-chip serial communication applications, through the serial port, our personal computers and SCM systems to communicate. PC as a PC, send down bit microcontroller system or ASCLL hexadecimal code, after receiving the SCM system with LED display received data and sent back up crew as data.)

基于STM32F4的示波器的源代码，内部含有ucos-ii操作系统。(STM32F4 based oscilloscope source code contains an internal ucos-ii operating system.)

温湿度串口检测程序，实现对数据的读取和检测(Temperature and Humidity Serial Port Detection Program for Data Reading and Detection)

说明：  vb与plc通讯帮助解决vb与plc通讯之间的问题(vb and Communications plc)
