AP3706电路图 AP3706电路图 -LED驱动，可以驱动5WLED驱动

芯片at89s52，在上面完成一些如led 点阵 PS键盘 串口 等基本操作 对于初学51的有参考价值-Chip at89s52, in the above example, the completion of some led dot matrix keyboard PS serial basic operation such as 51 for the beginner has reference value

此文档是我生产实习的源码，开发环境是Keil51,使用的控制CPU是华邦系列单片机，功能是实现恒温箱的交互控制-This document is my internship source code, the development environment is Keil51, control the use of the CPU is Winbond series microcontroller, is functional incubators of interactive control

STC单片机说明,与传统51比较,方便替代习惯于传统51的编程-STC Singlechip shows that compared with the traditional 51 to facilitate alternative programming accustomed to the traditional 51

一个很好的例程，希望对您有帮助，欢迎探讨

关于单片机（51系列）通过GPRS模块（LT8030）和服务器进行通信-on SCM (51) via GPRS module (LT8030), and communications servers

使用PIC芯片控制U2270读取125KHz ID卡卡号，因为所使用的PIC资源很少，此程序极为精简，包含中断曼切斯特解码和校验全过程，非常实用。-The use of PIC chip control U2270 Read 125KHz ID card number, because the use of PIC scarce resources, this program is extremely streamlined, with interruption of Manchester decoding and checking the whole process is very useful.

这是atmel公司的89C51SND1C的mp3源程序，flash用的是dataflash，支持fat16/32文件系统-This is the source 89C51SND1C mp3, flash is used dataflash, file system support Acronis
