Hi all. I am using Mythbuntu 11.04. I have ir-kbd-i2c mostly working with the remote from my PVR-350 except that back/exit is not working. I would like to get this button to send escape so I can exit out of the current screen on the frontend.

Using the "-t" option I can see the following when the back/exit key is pressed:



root@myth01:/etc/lirc# ir-keytable -t --sysdev rc3
Testing events. Please, press CTRL-C to abort.
1322883884.548449: event MSC: scancode = 1f
1322883884.648418: event MSC: scancode = 1f
dmesg shows:



[609773.271134] ir-kbd-i2c: ir hauppauge (rc5): s1 r1 t1 dev=30 code=31
[609773.271140] ir-kbd-i2c: ir_key_poll: keycode = 0x001f
So the question is, how do I map 0x001f to be "Escape"? Does ~/.mythtv/lircrc get used or ~/.lirc/mythtv? The keymap file that is open by the module is /usr/share/lirc/remotes/hauppauge/lircd.conf.hauppauge but the values there don't make sense to me. I am guessing I need to map 0x1f to KEY_ESC or KEY_EXIT but not sure how/where to do that.

Thanks,

I got this solved by the following command:


ir-keytable -p LIRC --sysdev rc3After doing this:


root@myth01:/etc/rc_keymaps# diff haupp haupp2
30c30
< scancode 0x001f = KEY_EXIT (0xae)
---
> scancode 0x001f = KEY_ESC (0x01)
