Description: 基于51的圈圈操作系统(51_00_OS)出来拉……
来这里下载整个程序包：
http://blog.21ic.com/more.asp?name=computer00&id=9501
*************基于51内核的圈圈操作系统****************
说明：这是圈圈在学习嵌入式操作系统后在51上写的一个简单的操作系统，提供创建任务，删除任务，任务调度，系统延时，任务挂起，发送消息，等待消息，CPU使用率统计，系统时间，串口发送、接收数据及串口资源管理等功能。由于时间匆忙，部分注释可能在调试时忘记更改，如有发现不能理解的注释，请给圈圈留言: http://blog.21ic.com/blog.asp?name=computer00
可使用keil自带的软件仿真，也可以使用硬件来运行，使用硬件时，上位机推荐使用windows自带的超级终端，关于超级终端的使用，可参看： http://blog.21ic.com/more.asp?name=iC921&id=8878-circle operating system (51_00_OS) Rafah ... out here to download the whole package : http :// blog.21ic.com/more.asp name = computer00

Description: 51开发板典藏版源代码+升级
里面有源代码，有3个工程,必须用VC2005打开，EXPRESS不行，低版本更不行。
USERGUIDE器件由于有加密，不便公开。重新作了一个NEWUG器件,电气功能
完全一样,可以放在任何地方用,不过DLL必须自己打开源代码编译(减小体积),
希望大家精力集中在学习知识,
