8O51的实用原理图和封装图，新鲜出炉，来着快快看，-8O51 practical schematic diagram and package diagram, freshly to look forward to as soon as possible,

T6963控制器的液晶驱动程序-T6963 MCU Controller Driver Source code

在STM32中进行数据擦出和书写，为程序调试存储数据提供了方便。这个个过程中熟悉，地址的强制转换，STM32单片机的IO口操作，还有Flash 的一些操作，对于初学者来说还是比较合适的。

arm2440下，linux2.6内核串口通信应用程序，各参数在源码内可灵活修改-arm2440 under, linux2.6 core serial communication applications, the parameters in the modified source code can be flexible

本文介绍了红外多路遥控系统。红外多路遥控系统可实现16路的红外开关控制。以码分制多通道红外遥控为设计的基本思路。通过键盘及代码生成电路、编码、脉冲调制振荡和红外发射构成红外发射电路。通过红外接收，解码以及由单片机控制的医码控制电路组成红外接收电路。-The passage has introduced the nfrared multichannel system of remote control. The infrared multichannel system of remote control can realize the infrared switch control of 16 roads. With yard divide into system the basic train of thought with much passageway infrared remote control of design. Through keyboard and code generation circuit, coding and pulse modulation vibration with infrared project to form infrared project circuit. Pass infrared take over , decode as well as the medical yard control circuit composition that controled by single flat machine are infrared to take over circuit.

校内竞赛做了一个PM2.5测量仪，采用pm2.5传感器DSM501A测得PM2.5的浓度并把它转化为脉冲量，通过51单片机检测脉冲量并把它转化为数字量，经过换算，送到LCD1602进行显示。
