51与pc串口通讯，主要用c语言编写，相信对初学者会有好处的-51 pc with serial communications, the main c language, I think it would be beneficial to the beginners

这是一个串行通信接口的实例就是在单片机时钟频率在12MHz 波特率 9600bps 的通信方式下实现软件UART的发送程序。 -This is an example of serial communication interface is a single chip at 12MHz clock frequency in the communication baud rate of 9600bps software UART implementation of the send process.

双机通信过程中采用点对点通信的主机部分示例-Two-machine communication process used in peer-to-peer communications in the host part of sample

本文以51单片机为例介绍如何扩展USB接口进行对U盘的读写，并详细介绍FAT16、FAT32文件系统的细节以及如何编码实现单片机对文件系统的常用操作，顺带提到一点关于U盘兼容性问题的解决经验。在这里单片机是host，U盘是slave。-In this paper, single-chip microcomputer 51 as an example on how to expand the USB interface on the U disk read and write, and details on FAT16, FAT32 file system and how to encode the details of the realization of single-chip microcomputer used for file system operations, mentioned in passing that on U disk experience compatibility problems. Here is a single-chip host, U disk is a slave.

本文给出了一种以80C31为主控CPU的固定电话短信息终端的设计，从系统软硬件两个方面说明了固定电话短信息终端的设计方法和各个部分的工作原理 -This paper proposes a 80C31 CPU for controlling the fixed telephone short message terminal design, system software and hardware from the two showed that the fixed telephone short message terminal design methods and various parts of the work principle

该程序是用C编写的，须下载到凌阳61单片机 有万年历功能-that the procedure was used in the preparation of C, to be downloaded to a microcontroller Sunplus 61 calendar function
