package com.bg7yoz.ft8cn;
/**
 * -----2022.5.6-----
 * MainViewModel类，用于解码FT8信号以及保存与解码有关的变量数据。生存于APP的整个生命周期。
 * 1.解码的总条数。decoded_counter和mutable_Decoded_Counter。
 * 2.解码消息的列表。消息以Ft8Message展示，列表用ArrayList泛型实现。ft8Messages，mutableFt8MessageList。
 * 3.解码和录音都需要时间同步，也就是以UTC时间的每15秒为一个周期。同步事件的触发由UtcTimer类来实现。
 * 4.当前的UTC时间。timerSec，更新频率（心跳频率）由UtcTimer确定，暂定100毫秒。
 * 5.通过类方法getInstance获取当前的MainViewModel的实例，确保有唯一的实例。
 * 6.用HamAudioRecorder类实现录音，目前只实现录音成文件，然后读取文件的数据给解码模块，后面要改成直接给数组的方式----TO DO---
 * 7.解码采用JNI接口调用原生C语言。调用接口名时ft8cn，由cpp文件夹下的CMakeLists.txt维护。各函数的调用接口在decode_ft8.cpp中。
 * -----2022.5.9-----
 * 如果系统没有发射信号，触发器会在每一个周期触发录音动作，因录音开始和结束要浪费一些时间，如果不干预上一个录音的动作，将出现
 * 连续的周期内录音动作重叠，造成第二个录音动作失败。所以，第二个周期的录音开始前，要停止前一个周期的录音，造成的结果就是每一次录音
 * 的开始时间要晚于周期开始300毫秒（模拟器的结果），实际录音的长度一般在14.77秒左右
 * <p>
 *
 * 2023-08-16 由DS1UFX提交修改（基于0.9版），增加(tr)uSDX audio over cat的支持。
