mipsandroid 遥控器设置

参照官网文档，在UBUNTU上编译mipsandroid，放置到SIGMA8655上测试运行。运行前必须修改相关文件

显示输出设置

如果不设置正确输出，屏幕上没有信号。

找到文件根目录下/system/etc/init.smp86xx.sh,将720P的输出改成

set_outports -digital -f HDMI_720p59 -component -f 720p59 -analog -f NTSC_M -audio_engine 0

遥控器按钮映射

Android中遥控器键值将映射成Android能处理的键值。因此mipsandroid必须加载两个驱动

 

insmod /lib/modules/virt_input.ko //虚拟输入驱动

insmod /lib/modules/irkernel.ko //遥控器驱动

系统从遥控器驱动读取键值映射成标准键值后发给虚拟输入驱动

mipsandroid通过启动virinput程序完成转换，源码位于/mipsandroid/vendor/sigma/smp86xx/virtinput/virtinput.c

修改键值映射static const IR_KEY nec_key_table[] = {{ 0xbc43e608, KEY_POWER, 0, "POWER" },{ 0xb847e608, KEY_EJECTCLOSECD, 0, "EJECT" },{ 0xbd42e608, KEY_1, 0, "1" },{ 0xbe41e608, KEY_2, 0, "2" }, { 0xbf40e608, KEY_3, 0, "3" },{ 0xb946e608, KEY_4, 0, "4" },{ 0xba45e608, KEY_5, 0, "5" }, { 0xbb44e608, KEY_6, 0, "6" },{ 0xb54ae608, KEY_7, 0, "7" },{ 0xb649e608, KEY_8, 0, "8" },{ 0xb748e608, KEY_9, 0, "9" },{ 0xb24de608, KEY_0,0, "0" },{ 0xb14ee608, KEY_CLEAR, 0, "CLEAR" },{ 0xb34ce608, KEY_SELECT, 0, "SELECT" },{ 0xb44be608, KEY_MODE,0, "TV/MODE" }, // { 0xe31ce608, KEY_DISPLAYTOGGLE,0, "VIEW/DISPLAY" }, { 0xe51ae608, KEY_SETUP,0, "SETUP" },{ 0xe619e608, KEY_MUTE,0, "MUTE" },{ 0xef10e608, KEY_VOLUMEDOWN,1, "VOL DOWN" },{ 0xe718e608, KEY_VOLUMEUP,1, "VOL UP" },//linjun_modify_20110309{ 0xe718fe01, KEY_UP,1, "UP" },{ 0xe619fe01, KEY_LEFT,1, "LEFT" },{ 0xe51afe01, KEY_RIGHT,1, "RIGHT" },{ 0xe41bfe01, KEY_DOWN,1, "DOWN" },{ 0xb04ffe01, KEY_ENTER,0, "ENTER" },//{ 0xeb14e608, KEY_UP,1, "UP" },//{ 0xe21de608, KEY_LEFT,1, "LEFT" },//{ 0xee11e608, KEY_RIGHT,1, "RIGHT" },//{ 0xe916e608, KEY_DOWN,1, "DOWN" },//{ 0xea15e608, KEY_ENTER,0, "ENTER" },{ 0xe11ee608, KEY_BACK,0, "RETURN" },{ 0xed12e608, KEY_MENU,0, "MENU" },{ 0xe01fe608, KEY_HOME,0, "HOME" }, { 0xe41be608, KEY_PREVIOUSSONG,1, "PREV" },{ 0xe817e608, KEY_PLAYCD,0, "PLAY" },{ 0xec13e608, KEY_NEXTSONG,1, "NEXT" },{ 0xa35ce608, KEY_REDO, 0, "REPEAT" },{ 0xa758e608, KEY_BACK,1, "REV" },{ 0xab54e608, KEY_STOPCD,0, "STOP" },{ 0xaf50e608, KEY_FORWARD,1, "FWD" },{ 0xa25de608, KEY_INFO,0, "INFO" }, { 0xa659e608, KEY_PREVIOUS,1, "SLOW REV" },{ 0xaa55e608, KEY_PAUSECD,0, "PAUSE/STEP" },{ 0xae51e608, KEY_NEXT,1, "SLOW FWD" },{ 0xa15ee608, KEY_EDIT,0, "EDIT/PROGRAM" }, { 0xa55ae608, KEY_TITLE, 0, "TITLE" },{ 0xa956e608, KEY_SUBTITLE,0, "SUBTITLE" }, { 0xad52e608, KEY_AUDIO,0, "AUDIO" },{ 0xa05fe608, KEY_SHUFFLE,0, "SHUFFLE" },{ 0xa45be608, KEY_ANGLE,0, "ANGLE/ROTATE" }, { 0xa857e608, KEY_SEARCH,0, "SEARCH" },{ 0xac53e608, KEY_ZOOM,0, "ZOOM" },}; 重新编译后的可执行文件拷到/system/bin下。

如果当前Android系统已经运行，KILL掉virtinput进程，重新运行该可执行文件。
