一个简单通用Android串口库

一、添加maven仓库

        maven {
            url 'https://packages.aliyun.com/maven/repository/2386483-release-mhUqVd'
            credentials {
                username = "6166b8fa89e1d5005a9f5792"
                password = "W49P9mYH7aoH"
            }
        }

二、添加依赖

implementation "com.lyn:serialport:1.0.0"

三、使用

 val serialPort = SerialPort()
        val fileDescriptor = serialPort.open("dev/ttyS3", 9600, 0)
        if (fileDescriptor!=null){
            Log.d(TAG,"打开成功")
        }else{
            Log.d(TAG,"打开失败")
        }
        //发送数据
        serialPort.getOutStream()?.write(byteArrayOf(0x00,0x00))
        
        //读取数据 
        serialPort.getInputStream()?.let { 
            Thread{
                while (true){
                    val available = it.available()
                    if (available<=0){
                        SystemClock.sleep(10)
                        continue
                    }
                    val data = ByteArray(available)
                    val read = it.read(data)
                    if (read>0){
                        Log.d(TAG,"读取成功:${data.contentToString()}")
                    }
                    SystemClock.sleep(10)
                }
            }.start()
            
        }

总结

总体使用还是比较简单的，希望对各位大佬有用，如有疑问欢迎评论区探讨，最后附上项目代码源码地址 gitee.com/longyn/I-an…
