arm9 s3c2440与zlg7290的接口程序。在 ADS1.2下通过编译并能运行。

this code gives an insight for accessing fast gpio ports in lpc 214x series

这是一个关于PCI驱动开发的开发文档资料,里面详细介绍了开发过程-This is a study on the development of PCI-driven development documentation, which details the development process

sst89c58下载器，使用keilc51的debug调试器下载。将本程序编译后写入sst89c58，并编程为remap 4kbytes。该芯片即有了keil环境下载功能,当p1.0拉低时，启动时进入下载程序，进入下载程序后将会自动删除block0,p1.0高电平时进入用户程序。 进入下载程序后，可以通过串口和keil的仿真环境连通，波特率自动调节,选择load HEX文件，即可将程序下载到sst89c58的低端32keeprom中。除了7e00-7fffh被占用-sst89c58 downloader, use the debug keilc51 Debugger download. This procedure compiled into sst89c58 and programming to remap 4kbytes. The chip has Keil environment that is the ability to download, p1.0 down, start the download entered into the download will be automatically deleted after block0, p1.0 to I enter the user program. After entering the download, through serial and Keil simulation environment connectivity, baud rate adjusts to choose load HEX documents, procedures and can be downloaded to the lower end of 32keeprom sst89c58 China. Apart from 7e00-occupied 7fffh

基于Verilog下的串口通信实验本实验所实现的功能以及相应的程序思想：验实现的功能有上位机向开发板发送数据，开发板接收以后通过数码管显示，并且将接收到的数据传回给上位机，通过串口调试助手将返回的数据显示出来。

在这里我写了要找到之间无数的输入数量最多的程序。我只是写并易于理解。还有在我的程序不存在困难。但逻辑是太重要了。
