AverTV DVB-T 777 and the remote
Posted 08-24-2007 at 05:39 AM by Caysho
I started to look at what is needed to get the remote working.
This indicates patching is possible, but there's a note about support being in more recent kernels.

The board is referenced as SAA7134_BOARD_AVERMEDIA_777 in the saa7134 source; SAA7134_BOARD_AVERMEDIA_A16AR is also mentioned, and seems to be the chipset reference - I've seen it in the win32 inf, so the 777 may simply be a derivative (?).
Searching on this finds a couple of things ...
This contains a reference to linux-2.6.19-rc6:
http://72.14.253.104/search?q=cache:9V0IrHWc38IJ:crypto.riken.go.jp/archives/linux/kernel.org/kernel/people/agk/patches/2.6/2.6.19/patch-2.6.19-rc5-rc6+%22mask_keycode+%3D+0x02F200%22&hl=en&ct=clnk&cd=4&gl=au&client=firefox-a
I'm guessing this is when support first got into the kernel.
This contains the same information, but a bit cleaner:
http://grmso.net:8090/blob/1b6dfd801cc1f6e9d0c3c95571b0eaf4974bf3b7/
This indicates there are values that need to be passed to lirc_gpio
http://osdir.com/ml/hardware.lirc/2004-04/msg00181.html
but I'm not clear on what they all are, or how to get them.
KnoppMyth R5F1 uses kernel 2.6.18-chw-13, so I'll either have to do some hacking, or get a more recent MythTV distro to use the remote right now.
One interesting bit of info is what
returns:
I gather this can be used in xorg, but I wonder if remote buttons can be mapped to different functions depending on which application is used ? I gather lirc can do this.
Some progress:
This gets the remote recognised as an additional keyboard.
Using Driver "evdev" also works, but there was no difference with respect to the keycodes returned.
I then played with xev to get the keycodes, and some didn't do anything. There are references to the syslog containing information about the key presses, but I didn't see anything.
showkey -k gives the raw data recieved.
Below are my findings [RM-FP model remote delivered with the 777):
Format is:
Button [OTHER FN]
keycode response on button press
RAW data with showkey -k
