USB(即Universal Serial Bus)是一种通用串行总线。随着技术水平的提高，计算机的广泛应用，人们对串行通信提出了更高的要求。开发一种兼容低速和高速的技术，从而为广大用户提供一种可共享的。可扩容的。使用方便的串行总线成为众多厂商的共同目标。为了实现整个计算机系统中总线的一致性，USB已发布了一种成为通用计算机串行技术规范，简称为USB。-USB (or Universal Serial Bus) is a Universal Serial Bus. With the skill levels improve, the wider use of computers, serial communication of a higher demand. The development of a compatible low-speed and high-speed technology, so as to provide a vast number of users can be shared. May be the expansion. Easy-to-use Serial Bus has become the common goal of many manufacturers. In order to realize the entire computer system bus consistency, USB has released a general-purpose computer serial become technical specifications, referred to as USB.

这篇文章发表在《单片机与嵌入式系统应用》2005年第三期，我已经和彭先生联系上了！他会回答大家的问题的 2002年初，笔者着手写一个IC卡预付费电表的工作程序，该电表使用Philips公司的8位51扩展型单片机87LPC764，要求实现很多功能，包括熄显示、负荷计算与控制、指示闪烁以及电表各种参数的查询等，总之，要使用时间的单元很多。笔者当时使用ASM51完成了这个程序的编写，完成后的程序量是2KB多一点。后来，由于种种原因，这个程序并没有真正使用，只是作了一些改动之后用在一个老化设备上进行计时与负荷计算。约一年后，笔者又重新改写了这些代码。

一个很有用的单片机实例,你在此例中会学会很多单片机系统的操作-Singlechip a useful example in this case you will learn a lot of single-chip microcomputer system operation
