用at90s2313做的usb转串口.很实用的哦

8051单片机点对多机通讯，希望对大家又所帮助，我也需要下载资料啊！-8051 points on the multi-machine communications, and they hope to also help everyone, I also need to download the information ah!

我自己编的一个一位数码管减计数的学习程序，在pic16f73已经验证了。-myself a part of a digital control by counting the learning process, as demonstrated in the pic16f73.

本文档包括单片机系统中常用到的时钟中断、通讯及键盘扫描等模块(见所附源程序)的说明。这些模块使用前后台系统模型。为达到最大的灵活性, 需要在用户工程中定义config.h文件, 在其中定义各模块可选参数的设置，而不是直接更改源代码。-this document, including SCM system clock used to the interruption communications and keyboard scanning modules (see accompanying source code) Note. These modules use before and after the Taiwan model. To achieve maximum flexibility in user defined config.h engineering documents, in the definition module optional parameter settings, and not to directly change the source code.
