2 | ## 安卓串口调试助手 V2016-05-05
3 | - 目前实现的功能:**串口开关、读写串口**
4 | - 待实现功能:*发送设置、接收设置*
5 |
6 | ## 测试
7 | 已在 Android 4.3 系统的开发板上进行过测试。
8 | ### 效果图

16 |
17 | ## 说明
18 | 1. 项目基于google code上的[android-serialport-api](https://code.google.com/archive/p/android-serialport-api/)
19 | 2. 移到Android Studio 2.1 平台上进行串口的NDK开发
20 | 3. 进行一系列简化操作
21 | 4. 还需完善
