超声波测距单元，在测距完成后在8位数码管上显示测距结果，可用于小车防撞。-Ultrasonic Ranging unit can be used for car crash

基于Xilinx公司的ISE软件开发的智能循迹避障小车的源代码，用Verilog语言，传感器有红外传感器以及超声波传感器-Xilinx' s ISE-based software development intelligent car tracking avoidance source code, using Verilog language, the sensor has an infrared sensor and ultrasonic sensors

此代码为可循迹小车的源码，实现红外遥控小车，以及超声波避障和红外循迹。-To follow tracing cart source code, the code so as to realize the infrared remote control cars, as well as ultrasonic obstacle avoidance and infrared tracking.

代码主要实现小车的红外避障以及超声波测距，进而控制点小车跟随人行走。-The main code of the car infrared obstacle avoidance and ultrasonic ranging, and then control point car to follow people walking.
