顶部端口(USB)接口,这个接口的调试是PL的使用
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.

本文讲述了linux操作系统下网络编程的相关步骤。
Linux的源码里,网络接口的实现部份是非常值得一读的,通过读源码,不仅对网络协议会有更深的了解,也有助于在网络编程的时候,对应用函数有更精确的了解和把握。
本文把重点放在网络接口程序的总体结构上,希望能作为读源码时一些指导性的文字。
-This article describes network programming under linux operating system of the relevant steps. Linux source code, the network interface to achieve most of it is very worth reading, by reading the source, not only on the network will have a deeper understanding of the agreement, will also help in network programming when the application has a more precise function understanding and grasp. This article focused on the network interface on the overall structure of the procedure, hoping for some guidance when reading source code of the text.

前段时间刚刚接触VC的串行通讯,在网上找到的了SerialPort类的使用方法,不过我想将这个类做在DLL中,然后在VB中做通讯界面调用。花了几天时间终于做完了,将SerailPort类的DLL工程共享一下,-Some time ago just contact VC serial communication, the Internet found the use of the SerialPort class, but I would like to do this class in the DLL, and then in the VB to do communication interface call. Spent a few days was finally done, and will SerailPort class DLL project to share what,
