Hi,

this is a utility to setup IR control keymaps using the /proc/av7110_ir 
interface.

just call 

   # ./av7110_loadkeys [-i|--invert] keymapname.(rc5|rcmm) > /proc/av7110_ir

If your IR receiver hardware inverts the signal, you should use the -i 
or --invert command line option.

now you can test your hardware setup using evtest

   # ./evtest /dev/input/eventX

where eventX is the IR input event device, usually event0 if you don't
use USB mice or keyboards.

------------------------------------------------------------------------

Keymaps are in format:

   <key> <associated input keycode>

   0x00   KEY_0
   0x01   KEY_1
   0x42   KEY_HOME

------------------------------------------------------------------------

In order to write a new keymap you might want to see the raw key 
values in the kernel log. Use

   # insmod dvb-ttpci.o av7110_ir_debug=1

in order to enable some verbosity in the av7110_ir driver. Then watch
the kernel log while pressing your remote control keys. When you don't see
any messages in your kernel log you should check all electrical connections,
the selected protocol (RC5 or RCMM?) and the inversion setting.

You find a list of all linux input key identifiers in </usr/include/input.h> 
and "./input_fake.h".

Please post new keymaps on the linux-dvb mailing list or send them to 
me <[e-mail]>.

have fun!
