Add the JitPack repository to your build file 6 | ``` 7 | //Add it in your root build.gradle at the end of repositories: 8 | allprojects { 9 | repositories { 10 | ... 11 | maven { url 'https://jitpack.io' } 12 | } 13 | } 14 | ``` 15 | Step 2. Add the dependency 16 | ``` 17 | //Add the dependency 18 | dependencies { 19 | implementation 'com.github.tyhjh:SerialPortUtil:1.0.0' 20 | } 21 | ``` 22 | 23 | ### 调用方法 24 | 读取文件权限应该是需要的 25 | ```java 26 | 27 | ``` 28 | 29 | 获取所有串口地址 30 | ``` 31 | String[] devicesPath = new SerialPortFinder().getDevicesPaths(); 32 | ``` 33 | 34 | 打开串口，设置读取返回数据超时时间 35 | ```java 36 | SerialPortService serialPortService = new SerialPortBuilder() 37 | .setTimeOut(100L) 38 | .setBaudrate(9600) 39 | .setDevicePath("dev/ttyS4") 40 | .createService(); 41 | ``` 42 | 43 | 发送指令 44 | ```java 45 | //发送byte数组数据 46 | byte[] receiveData = serialPortService.sendData(new byte[2]); 47 | 48 | //发送16进制的字符串 49 | byte[] receiveData = serialPortService.sendData("55AA0101010002"); 50 | Log.e("MainActivity：", ByteStringUtil.byteArrayToHexStr(receiveData)); 51 | ``` 52 | 53 | 打开或者关闭日志,默认关闭 54 | ```java 55 | serialPortService.isOutputLog(true); 56 | ``` 57 | //关闭串口 58 | ```java 59 | serialPortService.close(); 60 | ``` 61 | 62 | > 项目源码：https://github.com/tyhjh/SerialPortUtil 63 | -------------------------------------------------------------------------------- /app/.gitignore:
