R3300-M在Manjaro ARM 21.08系统下配置红外线遥控

在前面已经成功驱动了WIFI，于是再来看一看红外线：

$ dmesg | grep meson-ir

[    5.140483] rc rc0: meson-ir as /devices/platform/soc/c8100000.bus/c8100580.ir/rc/rc0
[    5.142659] rc rc0: lirc_dev: driver meson-ir registered at minor = 0, raw IR receiver, no transmitter
[    5.142827] input: meson-ir as /devices/platform/soc/c8100000.bus/c8100580.ir/rc/rc0/input4
[    5.147424] meson-ir c8100580.ir: receiver initialized

看起来红外线模块已经被成功识别并驱动。

再来看一看遥控文件：

有很多，但显然没有我使用的遥控器。计划找出按键对应值，然后根据模板创建。寻找按键映射参照 https://discourse.coreelec.org/t/how-to-configure-ir-remote-control/31 ，我之前做过Coreelec的，不知道是否可以直接照抄。（此部分待补充）

创建遥控文件后，可以利用按键调用系统命令，比如执行某个脚本，或者重启等等。参考 https://forum.armbian.com/topic/11161-lirc-on-armbian-buster/ ，作者使用triggerhappy实现功能：

# Samsung TV Remote Control
KEY_RED     1   /usr/local/bin/script.sh red
KEY_GREEN   1   /usr/local/bin/script.sh green
KEY_YELLOW  1   /usr/local/bin/script.sh yellow
KEY_BLUE    1   /usr/local/bin/script.sh blue

triggerhappy使用yay可以安装，有空测试下。
