路径
所有驱动路径
SerialPortFinder finder = new SerialPortFinder();String[] paths = finder.getAllDevicesPath();for (String path : paths) {Log.i("SerialPortFinder","path:"+path);}
通讯
初始化串口
Serial serial = new Serial("/dev/ttyMSM2",30001,SerialMode.RDWR);
设置监听
serial.setOnSerialListener(new OnSerialListener() {@Overridepublic void onSerialSend(byte[] data) {//发送内容}@Overridepublic void onSerialReceived(byte[] data) {//接收内容}});
打开串口
serial.open();
关闭串口
serial.close();
代理
服务配置
<serviceandroid:name="android.serial.port.api.SercdService"android:directBootAware="true"android:enabled="true" />
初始化
Sercd sercd = new Sercd(getContext());
网络接口列表 + 端口
String netInterface = "";
int port = 30001;
Map<String, String> map = sercd.feedNetworkInterfacesList();
for (String key:map.keySet()){//wifi是wlan0if (key.equals("eth0")){netInterface = map.get(key);}
}
设置监听
sercd.setOnSercdListener(new OnSercdListener() {@Overridepublic void onSercdStateChange(ProxyState proxyState) {System.out.println("proxyState:"+proxyState);}
});
开始代理
sercd.start("/dev/ttyMSM2",netInterface,port);
关闭代理
sercd.stop();
字节工具
Bytecode bytecode = new Bytecode();
byte b = 0b00001111;
Boolean值Byte
byte b = bytecode.toByte(false,false,false,false,true,true,true,true);//00001111
Byte的Boolean[]
boolean[] booleans = bytecode.toBooleans(b);//[false, false, false, false, true, true, true, true]
Byte转十六进制
String hex = bytecode.toHex(b);//0F
Byte转十进制
int dec = bytecode.toDec(b);//15
Byte转八进制
String oct = bytecode.toOct(b);//017
Byte转二进制
String bin = bytecode.toBin(b);//00001111
Byte数组转十六进制字符串
float floatValue = 99.99f;
byte[] data = bytecode.toBytes(floatValue);
String hexString = bytecode.toHex(data);//E1 FA C7 42
十六进制String转Byte数组
byte[] value = bytecode.toBytes(hexString);//[-31, -6, -57, 66]
Byte数组转Float
float floatValue = 99.99f;
byte[] data = bytecode.toBytes(floatValue);
float value = bytecode.toFloat(new byte[]{data[0],data[1],data[2],data[3]}));//99.99
Byte数组转Short
short shortValue = 33;
byte[] data = bytecode.toBytes(shortValue);
short value = bytecode.toShort(new byte[]{data[0],data[1]}));//33
Byte数组转Int
int intValue = 100;
byte[] data = bytecode.toBytes(intValue);
int value = bytecode.toInt(new byte[]{data[0],data[1],data[2],data[3]}));//100
