我做的超声波测距程序，基于at的8位单片机的，用c语言编写的。...

这是一个AVR单片机的头文件，有关引脚的位选，可BOOL输出输入，非常好用。我一直在用着。主要针对芯片ATMEGA128的头文件，其它的芯片也可向下兼容。-This is an AVR MCU header files, the pin-bit elections BOOL input-output, very easy to use. I have been using. ATmega128 chip aimed at the header files, other chips can also be backward compatible.

基于CY7C68013A的mouse+keyboard混合USB外设应用范例。本套代码基于CY3684开发板，使用多个interface实现复合设备。与之相对的另一种方案是使用多个报表描述符，该方案另行上传。-This project focuses on building a mouse+ keyboard hybrid USB device with the popular Cypress CY7C68013A chip. Implementation is based on a multiple Interface solution. Please refer to CY3684 dev kit documentation for more details regarding hardware platform.

改程序实现了C8051F120混合信号片上系统32位乘法，提高了在C8051上实现乘法的精度，较少了计算误差-Reform process to achieve the C8051F120 mixed-signal system-on-chip 32-bit multiplication to improve the C8051 to achieve precision multiplication, the calculation error of less

ts1620液晶显示的驱动，这种驱动网上一般很小有，是我自己写的并通过了测试-ts1620 LCD driver, which drives the Internet is generally very small, yes, I wrote it myself and passed the test

介绍keil c使用的详尽说明，英文版。可以支持较高的keil c版本-introduced a detailed account of the use of English. Support higher Keil c version

用单片机控制红外编码探测障碍物。本文提出解决干扰的方案是：由单片机控制发射有一定意义的红外编码脉冲串，同时，单片机接收该脉冲串。如果接收到的信号和发射的信号基本一致，才判断为有障碍物的存在。-MCU control infrared obstacle detection coding. In this paper, to resolve the interference of the program are: the launch by the single-chip control has a certain sense the infrared encoder pulse train at the same time, single-chip microcomputer to receive the pulse train. If the received signal and the signals are basically the same as the launch only to have to judge the existence of obstacles.
