基于移动终端的串口调试系统的设计与实现

摘要

Many devices have built-in serial ports for the purpose of configuration and diagnosis.Usually a laptop and a serial cable are used together to communicate with the device.We argue that this method is not a perfect solution due to the heavy weight of a laptop and the distance limitation of the serial cable. With the wide availability of cell phones and IPads,in this paper,we developed a new system that uses Android smart phone and Bluetooth technology to connect serial devices wirelessly.We developed a hardware bridge that can attach to the device serial port and translate the serial communication to Bluetooth,and hence can talk to Android phones.The software running at Android phone can send commands to and receive data from serial device through the hardware bridge.Our system removes the distance limitation of the serial cable and is also very lightweight and portable.%许多电子产品都带有串口，启用它们之前或复位以后都需要通过自身所带的串口进行一些初始化设置，通常都是使用笔记本电脑的串口，通过串口线连接进行初始化设置，由于接线麻烦，距离短，笔记本笨重，很不方便。随着手机和平板电脑等移动终端的普及和应用，为我们的工作带来了许多方便，也为实现无线调试这些设备成为可能。本文设计了一个基于安卓移动终端的串口调试系统，可以完成与各种具有串口的电子设备进行初始设置、调试等功能，极大提高了设备设置和调试的方便性。
