The sunxi-3.4 IR is exposed as a a keyboard on the Linux input device interface. For example, the following simple keybinder application might be used to run arbitrary commands when receiving a specific keycode via IR. You can install it by :|
$ git clone https://bitbucket.org/emiliolopez/keybinder.git
$ cd keybinder
$ sudo make install
Configuration is handled on /etc/keybinder.conf, as a "keycode,command" pair per line. The application prints every keycode received, so you may as well use it to figure out the keycodes you want to use.
To execute the application, run :
$ sudo keybinder /dev/input/event0
