****************************************************************************************************** WS_C100_7003V1.0_协和_7Inch_800x480_V.140108.img 软件名称: 主控-板号与版本号-屏尺寸-屏驱动-FLASH-客户-公司版本-日期.fw 备 注: 屏幕: 7.0"横屏,驱动IC: 界面: 按键: 收音: 无 SENSOR: 无 甩动: 无 游戏: 无 参考文件: 1. hsn_800x480_ECHO_favor_voice.rar(汉鑫诺SDK) 功能介绍: 1. 视频播放器 2. 应用: 主界面(home), 音乐(music), 视频(video), 相片(photo), 收音(fm), 录音(record), 电子书(ebook), 文件管理(explorer), 设置(setting); 3. 按键说明: 开/关 : 拔动开关; 0-9 : 数字点歌/视频; 播/停 : 播放/暂停, 确认; 音量+/- : 音量加减(文件管理时复用为上下键) 上/下曲 : 上/下一曲 movie : 视频快捷键; music : 音乐快捷键; FM : 收音快捷键; Record : 录音快捷键; Menu : 菜单键; Return : 返回键; 4. Line In功能; 检测到Line In线插入自动启动 LineIn应用, 5s后自动关屏省电(忽视系统当前背光状态), 退出后自动亮屏; Line In插入时不能切换到其他应用; 5. 插卡/U盘自动播放; 6. 混响功能; 当检测到外置麦克风插入时, 自动打开混响功能, 并通过I/O口控制开关管切断内置Mic, 防止啸叫; 7. 注意事项: 1. 功放底噪音优化; (1) 屏驱pwm频率要在30kHz以上; (2) 功放IC模式切到D类, 只有FM时切为AB类; 2. FM调试: (1) 进入背光自动设置为5s, 自动搜台时自动设为1s, 搜台完成后, 自动亮背光; 关背光是防止屏干扰到搜台和播放电台时的效果; (2) 进入FM后, 需要把功放IC的模式切换为AB类; 切为AB类后, FM搜台效果大增, 播放电台清晰; ********************************************************************************************************** 更新纪录: ************************************************************************************************************ 修改记录: WS_C100_7003V1.0_协和_7Inch_800x480_V.140108.img 1. 在赛尔佳WS_C100_702V1.0_赛尔佳_7Inch_800x480_V.131227.img软件基础上修改而来; 2. 在赛尔佳软件的基础上增加 旋钮按键 检测用于控制混响效果, 在rocker.drv中增加一通道专门给旋钮检测使用; 并在驱动中加入标志, 只有在需要读旋钮的值时才打开该通道, 同时暂时屏蔽其他按键的检测; 3. 由于客户需求要通过组合按键进入升级模式(3个IO口短接), 故增加矩阵按键驱动, 将部分按键用矩阵实现; Ethan. 2014-01-08(Wed.) ________________ WS_C100_7003V1.0_协和_7Inch_800x480_V.140124.img 1. 修复音乐定时断点记忆后出现连续死机问题; Ethan. 2014-01-24(Fri.) ________________ WS_C100_7003V1.0_协和_7Inch_800x480_V.140303.rar 1. 修复不能解析加密TF卡问题(更换epos); Ethan. 2014-03-03(Mon.) ________________ WS_IMG_C100_MX579V1.0_协和_7Inch_800x480_V.140513.rar 1. 电池电压检测修改为3.2V低电;(硬件上AVCC为3V) 2. FM界面频率显示重叠问题; Ethan. 2014-05-13(Tue.) ________________ WS_IMG_C100_MX570V1.0_协和_7Inch_800x480_V.140606.rar 1. 更换背景; 2. 背光亮度最大15; Ethan. 2014-06-06(Fri.) ________________
