FPGA把每路测距单元计算得到的障碍物距离信息通过RS-232接口传输到上位机，便于后续应用或上位机界面显示。同时，为了提高测距仪器的便携性，还为其安装了液晶显示屏，实时显示各路距离信息-FPGA put obstacles ranging from Each unit calculates the information obtained via RS-232 interface to transfer to the host computer to facilitate subsequent application or PC interface display. Meanwhile, in order to improve the range finder portability, but also for the installation of a liquid crystal display, real-time display distance information from various quarters
