优龙2440开发板的测试程序（ADS 编写）

这是一个用于创建多线程的程序，用法简单，内有例子，开消非常小，适合用于较低性能cpu上如51，arm7-This is a used to create multi-threaded program, usage is simple, there are examples, the extinction is very small, suitable for low performance on the cpu, such as 51, arm7

最新版的基于 Windows CE 的视频捕获解决方案，中微星301视频芯片，在 X86、ARM9、MIPS 等平台上有良好的表现效果，试用版，可持续运行15分钟。-The latest version of Windows CE-based video capture solution, in the MSI 301 video chip, the X86, ARM9, MIPS and other platforms have a good performance results, a trial version, sustainable operation for 15 minutes.

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.

采集AIN0和AIN1的信号，通过可调电阻，使输入的模拟信号发生改变，来进行A/D转换。为保证数据的准确性，通常采集10次以上，在求平均值。A/D转换器采集AIN0和AIN1的信号,并显示出来。-AIN1 acquisition and AIN0 signal, through an adjustable resistor, so that the analog signal input to change, to carry out A/D conversion. In order to ensure the accuracy of the data is usually collected 10 times more than the average in the order. A/D converter and acquisition AIN0 signals AIN1 and displayed.
