1.查看键盘映射
getevent 获取event设备
root@android:/ # getevent
add device 1: /dev/input/event3
name: “Microsoft Microsoft Basic Optical Mouse v2.0 “
could not get driver version for /dev/input/mouse1, Not a typewriter
add device 2: /dev/input/event2
name: “cec_input”
add device 3: /dev/input/event0
name: “ScalarPolicy”
could not get driver version for /dev/input/mice, Not a typewriter
add device 4: /dev/input/event1
name: “aml_keypad”
could not get driver version for /dev/input/mouse0, Not a typewriter
[ 8711.189102@0] fcode map = 0 press ircode = 0x0f, scancode = 0x006c
/dev/input/event1: 0001 006c 00000001
/dev/input/event1: 0000 0000 00000000
[ 8711.458565@0] fcode map = 0 release ircode = 0x0f, scancode = 0x006c
/dev/input/event1: 0001 006c 00000000
/dev/input/event1: 0000 0000 00000000
可以确定，使用的遥控输入设备是aml_keypad
dumpsys input
3: aml_keypad
Classes: 0x0000002b
Path: /dev/input/event1
Descriptor: 485d69228e24f5e46da1598745890b214130dbc4
Location: keypad/input0
UniqueId:
Identifier: bus=0x0010, vendor=0x0001, product=0x0001, version=0x0100
KeyLayoutFile: /system/usr/keylayout/Vendor_0001_Product_0001.kl
KeyCharacterMapFile: /system/usr/keychars/Generic.kcm
ConfigurationFile:
HaveKeyboardLayoutOverlay: false
获得使用的kl，查看对应的键值，例如：
key 61 CALL
key 97 DPAD_CENTER
key 232 DPAD_CENTER
key 108 DPAD_DOWN
key 103 DPAD_UP
key 102 HOME
key 105 DPAD_LEFT
key 106 DPAD_RIGHT
2.遥控器配置
查看遥控器spec，获取按键码值
映射上述的kl文件。
修改device/amlogic/g30ref/remote.conf
1.factorycode
遥控器的客户码，比如说客户码为00BD
factorycode =0xbd000001
后面固定为0001，前面记得位置换一下。
2.常用按键
left_key_scancode = 0x49
right_key_scancode = 0x4a
up_key_scancode = 0x0b
down_key_scancode = 0x0f
ok_key_scancode = 0x0d
根据遥控器的码值修改
3.键值映射区
key_begin
0x01 116
0x0f 113
0x6a 60
0x0b 103
0x0d 97
0x0f 108
0x49 105
0x4a 106
0x0a 139
0x55 102
0x54 158
0x0C 115
0x10 114
0x58 121
0x57 120
0x5e 102
0x5f 102
key_end
0x49 为遥控器码值，105为kl文件中left的key
