AndroidSerialTool

Description

Android 串口通讯 协议封装 针对一般数据帧Frame的处理：

一般帧指令分为几个部分

| STX | RSCTL | DATA | BCC |ETX | :-----| ----: | :----: |:----: |:----: |

|字段 | 描述 | |----- |----- | |STX | 帧开始标志，取值为FFFFH，2byte； | |RSCTL | 串口帧序列号,1byte <br> (1)RSU发送的串口帧序列号的低半字节为8，高半字节一般为0～7;<br>(2)PC发送的串口帧序列号是将收到的串口帧序列号高低半字节互换;<br>(3)RSU发送的串口帧序号为X8H,其中X为0～7;<br>(4)PC发送的串口帧序号为8XH,其中X为0～7;| |DATA |发送的帧指令数据；| |BCC |异或效验值，1byte，从RSCTL到DATA所有字节的异或值；| |ETX |帧结尾，取值为FFH,1byte;|

Android SerialPort protocol for #command

Overview

This library provide support for android-serialport protocol https://code.google.com/archive/p/android-serialport-api/ At now library works only as client for backend with support SerialPort-Command, such as NodeJS (SerialPort.js or other) or Spring Boot (SockJS).

Add library as gradle dependency

repositories { 
    jcenter()
    maven { url "https://jitpack.io" }
}
dependencies {
    implementation 'com.github.jambestwick:AndroidSerialTool:{latest version}'
}

Example library usage

Basic usage

        SerialPortUtil.getInstance().openSerialPort();
        /**
        **writeCommand Thread
        **/
        SerialPortUtil.getInstance().SERIAL_EXECUTOR.execute(new SerialPortUtil.WriteSerialPort("FFFF000001FF"));
        
        /**
        **readCommand Thread with callBack interface
        **/
        SerialPortUtil.getInstance().SERIAL_EXECUTOR.execute(new SerialPortUtil.ReadSerialPort(this));
 
        SerialPortUtil.getInstance().closeSerialPort();
