QtCreator打开CarPlayMainWW和MusicPlayerWW的工程文件，可执行文件由qmake执行后生成。 45 | 2. 运行CarPlayMainWW可执行文件。 46 | 47 | ## 改进日志 48 | 49 | - TODO 50 | - [ ] 读取音乐文件的方式改为本地指定路径自动读取，取消数据库增删、解析歌曲信息功能 51 | - [ ] 更多的应用...... 52 | 53 | - V1.1 54 | - [x] 使用多线程 55 | - [x] 添加arm版本，编写SR04超声波测距模块驱动程序，在Qt上编写传感器数据采集的线程 56 | - [x] Menu初始化时MusicPlayer一起启动，且MusicPlayer第一次启动时隐藏界面 57 | -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/bluetooth.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/bluetooth.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/car.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/car.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/map.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/map.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/music.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/music.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/phonecall.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/phonecall.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/settings.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/settings.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Icon/weather.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Icon/weather.png -------------------------------------------------------------------------------- /arm/CarPlayMainWW/Assets/Image/background-main.jpg: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/RaviShekdar/imx6ull_Qt5-CarPlay/19f57c0710a08ef62618775b62494329a17c8e98/arm/CarPlayMainWW/Assets/Image/background-main.jpg -------------------------------------------------------------------------------- /arm/CarPlayMainWW/CarPlayMainWW.pro: -------------------------------------------------------------------------------- 1 | QT += core gui 2 | 3 | greaterThan(QT_MAJOR_VERSION, 4): QT += widgets 4 | 5 | CONFIG += c++11 6 | 7 | # The following define makes your compiler emit warnings if you use 8 | # any Qt feature that has been marked deprecated (the exact warnings 9 | # depend on your compiler).
