本角速度传感器的原理是将旋转时音叉震荡产生的地球偏转力（克里奥利力）转换为电信号研制成功的。本传感器由：传感器件、音叉驱动电路和信号处理电路。音叉由石英音叉和电极组成。以上构成本角速度传感器。-The angular rate sensor is the principle of rotation of the Earth when the tuning fork vibration generated deflection force (Coriolis force) is converted to electrical signals successfully developed. The sensor consists of: sensor, tuning fork drive circuit and signal processing circuits. And electrodes from the quartz tuning fork tuning fork composed. Above constitute the angular rate sensor.

关于arm开发的文档集合 有uCLinux ,usb应用,以及开发步骤等等,非常不错,-development arm of the document set a uCLinux, usb applications, and the development of steps and so on. very good.

这个里面好象是关于一个二极管显示的程序~~~~~ api里面的config是一些配置；led好象是二极管显示具体的硬件操作，sio是串口方面的东西，timer是记时器 app里面是主函数main()程序从这里开始执行的 include里面是这些程序里面的一些头文件的声明

周立功D12开发板中带的WINDOWS XP驱动程序，在编译后会出现USB设备不能正常工作. 以下是修改的代码,修改后可以正常工作. 在d12.c和Ioctl.c中, 将+256去掉,这个会引去枚举设备时,设备描述符的长度不对,修改后: siz = sizeof(USB_CONFIGURATION_DESCRIPTOR) 在d12.c中的D12_SelectInterface函数中, 设备查询完接口后有一段代码,也会引起驱动返回不对,需要屏蔽下面的代码 // Retrieve the selected Configuration and Interface 修改上面两处后,USB可以正常使用了. -weeks D12 development board, who were brought to the Windows XP drivers, the compiler will happen after the USB device not working properly. Following is the revised code, revised after normal work. In d12.c and Ioctl.c, 256 will be removed, this will generate to Enumerate equipment located descriptors up the length wrong, the revised : not = sizeof (USB_CONFIGURATION_DESCRIPTOR) in the D12_SelectInterface d12.c function, equipment End interface for a period after the code can also lead to wrong drivers need to shield the following code// Retrieve the selected Configuration Interface and the above two changes, USB can use the normal.
