下面是一个超声波测距的程序，硬件电路由于电脑格盘已丢失，下面的代码是从样机上复制的。
硬件电路包括液晶显示、超声波的发射、超声波的接受、滤波、单片机处理。
液晶显示采用LCD1602模块，下面的代码里有液晶的驱动，可以拷贝用于它处。
超声波发射电路包括压电换能器及其支持电路，发射约44KHz的超声波。
超声波的接收电路包含一块CD40106处理芯片。技术指标大约是测距范围在三米左右，测量精度约在厘米级别。大量用于倒车雷达的测距中。-The following is a range of ultrasound procedures, the hardware circuit as a result of the computer grid plate has been lost, the following code is copied from the prototype. Hardware circuit including liquid crystal display, ultrasonic transmitter, ultrasonic acceptance filtering, single-chip processing. LCD1602 LCD module used, the following code, there are LCD drivers, you can use it to copy. Firing circuit including the piezoelectric ultrasonic transducer and its support circuitry, fired about 44KHz ultrasound. Ultrasonic receiver circuit includes a processing chip CD40106. Technical indicators for a range of about 3 meters range around the measurement precision level of about cm. Reversing a large number for the location of the radar.

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.
