介绍说明－－下载内容来自于网络，使用问题请自行百度
Hydrogen/C51 是一个用于51的非占先操作系统 基本上用纯 C 实现, 嵌入了大概10行的汇编
基本需求:
1.最小编译代码大概在 2.4k
2.需要使用片外的 xdata 作为堆使用
3.占用 TIMER0 作为计时
使用基本要求:
1.任务中必需要存在 Sleep/WaitFor 函数才能主动放弃占用CPU
2.任务入口和使用到Sleep/WaitFor的函数必需是 reentrant.
内核功能:
1.动态建立任务
2.支持事件/阻塞/信号量,临界
3.全双工串口(中断实现), IO过程中不会阻塞其它任务
4.UNIX c 风格的读写流(read/write)
5.一个简单的基于 24C 的文件系统(不支持目录)
-Hydrogen/Core51 is a Keil C51 None-Preemptive OS. CORE written by Pure C (well..almost Pure, has 10 lines inline ASM).
CORE minimal resource
**Size about 2.3~5K ROM, 20+ Byte RAM. it is depends modules your chosen.
**CORE also TAKE TIMER0 to tick for real-timing, and need xdata for HEAP
CORE Support
**dynamic Create/Terminate Thread(TASK)
**Synchronize Object (Event/Semaphore/Critical Section), Thread(TASK) Naturally GIVES UP CPU by WaitFor these Synchronize Object
**Common IO, it is STD C open/read/write in Any Stream Like IO(I2C, UART etc.)
I host this project for OS studying, and Also Used in my work.
SRC can be download from SVN Repository
