基于凌阳单片机SPE061A的超声波测距程序，具有短距离测距，中距离测距和可调距离测距等三种功能，运用凌阳大学计划所提供的开发板，可以很容易实现障碍物距离的检测-Based on Sunplus SPE061A Singlechip Ultrasonic Ranging procedure, with short-distance ranging, ranging in distance from the rangefinder and adjustable three functions, the use of Sunplus University plans provided by a development board, can easily realize the obstacles Detection of objects distance

IC卡操作软件:AT88SCl604芯片的操作模式有五种。它们是通过配PGM、RST、CLK等引脚信号及内部地址计数器(IAC)的状态组合来实现。 (1) 芯片复位操作： AT88SCl604有两种复位方式:上电复位和控制复位。 上电复位： 上电复位是当芯片加电时的最初状态。上电复位属于芯片 内部复位。它将使芯片内部所有的隐含标志复位到"0"状态。并使地址计数器复位到0位。 控制复位： 当CLK为低时，在RST脚上的一个下降沿将便芯片产生复位操作。 控制复位是将地址计数器复位到0位，而不影响任何内部标志的状态。-IC Card operating software : AT88SCl604 chip mode of operation there are five. They are allocated by PGM, RST, etc. pin CLK signal and the internal address counter (IAC) portfolio of the state is to be achieved. (1) chip reset operation : reduction AT88SCl604 two ways : power-on reset and reset control. Power-on reset : power-on reset when the chip is in power at the initial state. Power-on reset the internal chip is reset. It will enable all internal chip implied signs reset to "0" state. Make address counter reset to 0. Reset control : When the CLK for the low, the RST feet of a falling edge chips will have to reset operation. Reset control is to address counter reset to 0, without prejudice to any signs of internal sta
