根据上面的代码却解析数据举例： 1,10,0,10.56,0.1234,0.23456,75.0

根据上面的代码，可以得知该数据的格式为：

协议头：10Hz
帧序号：1
系统状态：POSITION_1（取值为0x01）
寻北进度：0
航向角：10.56
俯仰角：0.1234
横滚角：0.23456
实时数据类型：BATTERY_VOLTIGE（取值为0x00）
实时数据：75.0

因此，该数据的完整字符串表示为："10Hz1,1,0,10.56,0.1234,0.23456,75.0\r\n"

如何根据这个协议public class Protocol { private static final String PROTOCOL_HEADER = "10Hz,"; private static final String PROTOCOL_SEPARATOR = ","; private static final String PROTOCOL_NEWLINE = "\r\n"; private int frameNumber; private int systemState; private int northProgress; private float headingAngle; private float pitchAngle; private float rollAngle; private float realTimeData; public Protocol(int frameNumber, int systemState, int northProgress, float headingAngle, float pitchAngle, float rollAngle, float realTimeData) { this.frameNumber = frameNumber; this.systemState = systemState; this.northProgress = northProgress; this.headingAngle = headingAngle; this.pitchAngle = pitchAngle; this.rollAngle = rollAngle; this.realTimeData = realTimeData; } public String toString() { StringBuilder builder = new StringBuilder(); builder.append(PROTOCOL_HEADER); builder.append(frameNumber).append(PROTOCOL_SEPARATOR); builder.append(systemState).append(PROTOCOL_SEPARATOR); builder.append(northProgress).append(PROTOCOL_SEPARATOR); builder.append(headingAngle).append(PROTOCOL_SEPARATOR); builder.append(pitchAngle).append(PROTOCOL_SEPARATOR); builder.append(rollAngle).append(PROTOCOL_SEPARATOR); builder.append(realTimeData).append(PROTOCOL_NEWLINE); return builder.toString(); }}解析这个数据举例： 1,10,0,10.56,0.1234,0.23456,75.0

这个协议的数据结构是固定的，每个字段的意义如下：

- frameNumber：帧数
- systemState：系统状态
- northProgress：北向进度
- headingAngle：航向角
- pitchAngle：俯仰角
- rollAngle：横滚角
- realTimeData：实时数据

根据这个协议，数据 "1,10,0,10.56,0.1234,0.23456,75.0" 可以解析为：

- frameNumber = 1
- systemState = 10
- northProgress = 0
- headingAngle = 10.56
- pitchAngle = 0.1234
- rollAngle = 0.23456
- realTimeData = 75.0

如果你想要解析更多的数据，只需要将数据按照协议中定义的格式进行拼接，然后再使用相应的方法进行解析即可。
