用STC89C51实现红外对管的数据传输：1、先用一块STC单片机接好接受电路，利用数码管显示测试用的红外遥控器（一般买的开发版，都有一个小的红外遥控器），对比数据是否正确；2、上述完成并实现，利用第二块板子接好发射管电路（我是分开的，软件包里有2个代码，一个发射程序，一个接受程序）；3、都实现后，可以修改发射端的代码，会在接受电路的数码管上看见不同的数据，这样就实现了数据的传输，协议大家可以自己写。个人感觉发射端比较重要，红外采用PPM编码方式，一定要注意1和0高低电平的是时间。

局域网，广域网监控源代码，我自己编写的只要公司经理安装一个服务器端，然后在员工的电脑安装客户端，经理就可以随时知道每个员工在做什么，要是员工做别的事，经理可以发送警告信息，同时把员工的行为记忆下来，强烈推荐。- The local area network, the WAN monitoring source code, I compile so long as company executive installs a server end, then in staff s computer installment customer end, manager may know as necessary each staff is making any, if the staff makes other matter, manager may transmit the warning information, simultaneously gets down staff s behavior memory, intense recommendation.

WINDOWS 串口编程 调试程序 第四部分-WINDOWS serial programming debugger Part IV

TOP PORT (USB) 调试接口说明 本接口是利用PL-2303HX的USB转RS232的接口芯片设计实现了一个TTL(5V)的RS232串口，并且利用了PL-2303HX的2个GPIO口软件模拟了一个低速的I2C总线.该接口由USB接口提供5V电压，可自带2Kbit(24C02)数据备份EEPROM (单独读写通道,不占用I2C总线地址)。并可对外提供小于250mA的5V电压。尤其适合WIN-XP以后的没有并口和串口笔记本电脑。整机成本不到￥20RMB。 -TOP PORT (USB) interface debugging of this interface is the use of PL-2303HX the USB to RS232 interface chip design to achieve a TTL (5V) of the RS232 serial port, and use of PL-2303HX the two GPIO port software simulation of a low-speed I2C bus. The interface from the USB interface to provide 5V voltage, can bring their own 2Kbit (24C02) data backup EEPROM (separate read and write access, do not occupy I2C bus address). And may provide less than 250mA of 5V voltage. WIN-XP is particularly suitable for subsequent parallel and serial no notebooks. Machine costs less than ￥ 20RMB.
