这是一个不到2000行的操作系统,巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间,每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1),但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样,设置MVA对应的页表指向不同物理地址就可以很方便地让各进程运行空间相互隔开。代码很少,注释丰富,希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。
-This is a trip of less than 2000 operating system, cleverly using ARM9 CPU memory management unit (MMU) to achieve the switching process. ARM9 4G virtual address can be divided into 128 process space, each 32M. While their virtual address (VA) are 0- (32M-1), but the corresponding MVA (Modified Virtual address, and by the virtual address VA and the process of portfolio from PID) not the same, set MVA corresponding page table at the different physical address can be very easy to let the the process of separating the mutual operation of space. Code rarely Notes rich, in hopes of understanding the operating system, understanding the ARM architecture friends help.

his project was built and tested with WinAVR
his project was built and tested with WinAVR-20060125.
Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!!
To build the code, just install WinAVR and run "make" from the console in echomaster and
echoslave subdirs.
"make program" will program the device if you have a AVRISP attached.
Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock
from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST!
Otherwise you wont get any clock signal to the AVR and then you can t program it or reset
the fuses!
The MC1319x has default clock output of 32kHz so you will have to set your programmer to
a very low frequency (

通过STM32的USART2连接ATK-HC05蓝牙模块,
资源描述本实验将实现如下功能:
1,通过STM32的USART2连接ATK-HC05蓝牙模块,检测并显示蓝牙模块的状态.
2,通过KEY0按键可以开启/关闭定时向ATK-HC05蓝牙模块发送数据(ALIENTEK HC05 xx)测试蓝牙模块的数据发送.
3,可以通过WK_UP按键设置ATK-HC05蓝牙模块的主从工作模式.
4,可以通过LCD显示ATK-HC05蓝牙模块接收到的数据.
5,可以通过USMART对ATK-HC05蓝牙模块进行AT指令查询和设置.
6,结合手机端蓝牙软件(蓝牙串口助手 v1.97.apk),可以实现手机无线控制开发板(点亮和关闭LED1).
硬件连接:
STM32开发板-->ATK-HC05蓝牙模块
PA2-->RXD
PA3-->TXD
PC4-->KEY
PA4-->LED
GND-->GND
5V/3.3V-->VCC
