+# SerialPortHelper（Android串口通信）
+
+Android串口通讯助手可以用于需要使用串口通信的Android外设，该库有如下特点：
+
+1. 串口通信部分使用C++实现，在笔者接触的部分设备上实测，使用C++实现与Google官方提供的Demo的方式要快；
+2. 支持且必须设置串口接收最大数据长度，初始化库时填入该参数，这样设置的原因是考虑在实际使用中，规定的串口通信协议格式一般会固定有最大长度，方便对数据进行处理；
+3. 支持命令一发一收，通过对串口的读写线程进行同步控制，命令会先加入到队列然后依次发送和接收，前提需要设置超时时间以及超时处理，参考下面第4、5点；
+4. 支持超时设置，设置超时时间后，如果命令在设置的时间内未反馈，则会根据设置的操作进行重发或退出该命令；
+5. 支持超时重发（可以N次重发，具体按需设置）与退出，退出会调用接收回调的 **onComplete** 方法。
+
+### 1、DEMO演示
+
+使用该库简单实现的串口调试助手工具，[APK下载](https://github.com/freyskill/SerialPortHelper/blob/master/SerialPortHelperV1.0.1.apk)
+
+![image](https://github.com/freyskill/SerialPortHelper/blob/master/SerialPortHelper.png)
+
+
+
+### 2、接入方式
+
+#### Step 1. Add the JitPack repository to your build file
+
+Add it in your root **build.gradle** at the end of repositories:
+
+```groovy
+allprojects {
+	repositories {
+		...
+		maven { url 'https://www.jitpack.io' }
+	}
+}
+```
+
+#### Step 2. Add the dependency
+
+```groovy
+dependencies {
+         implementation 'com.github.freyskill:SerialPortHelper:v1.0.1'
+}
+```
+
+
+
+### 3、使用说明
+
+初始化需要设置maxSize，也可以设置isReceiveMaxSize该参数默认为false，详细说明如下：
+
+int maxSize;  // 设置串口读取的最大数据长度
+
+boolean isReceiveMaxSize; // 设置是否接收命令按最大长度进行返回，比如串口协议定义的格式长度为16个字节，这样可以设置maxSize为16，然后设置该参数为true，则接收的命令就会返回16个字节的长度。
+
+ **提示：** 设置isReceiveMaxSize为true是为了处理命令返回不完整的情况，例如完整命令长度为16，但是串口读的过程分几次返回。
+
+```java
+SerialPortHelper serialPortHelper = new SerialPortHelper(32);
+SerialPortHelper serialPortHelper = new SerialPortHelper(32,true);
+```
+
+#### 3.1.初始化串口
+
+```java
+//方式一：快速接入方式，设置好串口地址，或者地址和波特率即可，数据位、停止位、校验类型分别默认为8、1、N。
+SerialPortHelper serialPortHelper = new SerialPortHelper(32);
+//serialPortHelper.openDevice("dev/ttyS0");
+serialPortHelper.openDevice("dev/ttyS0",11520);
+// 数据接收回调
+serialPortHelper.setSphResultCallback(new SphResultCallback() {
+            @Override
+            public void onSendData(SphCmdEntity sendCom) {
+                Log.d(TAG, "发送命令：" + sendCom.commandsHex);
+            }
+
+            @Override
+            public void onReceiveData(SphCmdEntity data) {
+                Log.d(TAG, "收到命令：" + data.commandsHex);
+            
+            }
+
+            @Override
+            public void onComplete() {
+                Log.d(TAG, "完成");
+            }
+        });
+```
+
+```java
+//方式二：通过SerialPortConfig设置相关串口参数
+
+//串口参数
+SerialPortConfig serialPortConfig = new SerialPortConfig();
+serialPortConfig.mode = 0;            // 是否使用原始模式(Raw Mode)方式来通讯
+serialPortConfig.path = path;         // 串口地址
+serialPortConfig.baudRate = baudRate; // 波特率
+serialPortConfig.dataBits = dataBits; // 数据位 取值 位 7或 8
+serialPortConfig.parity   = checkBits;// 检验类型 取值 N ,E, O
+serialPortConfig.stopBits = stopBits; // 停止位 取值 1 或者 2
+
+// 初始化串口
+serialPortHelper = new SerialPortHelper(16);
+// 设置串口参数
+serialPortHelper.setConfigInfo(serialPortConfig);
+// 开启串口
+isOpen = serialPortHelper.openDevice();
+if(!isOpen){
+    Toast.makeText(this,"串口打开失败！",Toast.LENGTH_LONG).show();
+}
+// 数据接收回调
+serialPortHelper.setSphResultCallback(new SphResultCallback() {
+    @Override
+    public void onSendData(SphCmdEntity sendCom) {
+        Log.d(TAG, "发送命令：" + sendCom.commandsHex);
+    }
+
+    @Override
+    public void onReceiveData(SphCmdEntity data) {
+        Log.d(TAG, "收到命令：" + data.commandsHex);
+        
+    }
+
+    @Override
+    public void onComplete() {
+        Log.d(TAG, "完成");
+    }
+});
+```
+
+#### 3.2.数据发送与接收
+
+```java
+// 发送数据
+serialPortHelper.addCommands(sendHexTxt);   // 发送十六进制字符串
+serialPortHelper.addCommands(sendComBytes); // 发送字节数组
+
+// 发送数据实体
+SphCmdEntity comEntry = new SphCmdEntity();
+comEntry.commands = commands; // 发送命令字节数组
+comEntry.flag = flag;         // 备用标识
+comEntry.commandsHex = DataConversion.encodeHexString(commands);  // 发送十六进制字符串
+comEntry.timeOut = 100;       // 超时时间 ms
+comEntry.reWriteCom = false;  // 超时是否重发 默认false
+comEntry.reWriteTimes = 5;    // 重发次数 
+comEntry.receiveCount = 1;    // 接收数据条数，默认为1
+serialPortHelper.addCommands(comEntry);
+```
+
+```java
+// 数据接收回调
+serialPortHelper.setSphResultCallback(new SphResultCallback() {
+    @Override
+    public void onSendData(SphCmdEntity sendCom) {
+        Log.d(TAG, "发送命令：" + sendCom.commandsHex);
+    }
+
+    @Override
+    public void onReceiveData(SphCmdEntity data) {
+        // 对于接受数据的SphCmdEntity，其中需要使用的有 
+        // commandsHex 返回的十六进制数据
+        // commands    返回的字节数组
+        // flag        备用标识，例如标识该命令是相关操作
+        Log.d(TAG, "收到命令：" + data.commandsHex);
+        
+    }
+
+    @Override
+    public void onComplete() {
+        Log.d(TAG, "完成");
+    }
+});
+```
+
+### 4、关闭串口
+
+```java
+serialPortHelper.closeDevice();
+```
