I won't be able to do anything with my screen resolution, sadly Intel refuses to write windows 7 64bit drivers for the GMA 3650 graphics adapter on my motherboard. I am stuck at 800x600.
Did anyone figure out how to program their left panel buttons yet?
All I can do is change their color, and when I do it, selecting blue makes the buttons glow green, green turns them red, and red turned them gray, and white turns them off.
I tried configuring the bottom buttons for volume up and down, but nothing happens when I press them except the light burns brighter for a few seconds. I was wondering if I need to do anything special like put any of the files in a system directory or something?
Has there been any word on the left button panel availability? I sure would like to get my setup finished. =)
A couple of us got the left panel buttons from Derrick, by emailing him directly with inquery.
I loaded the USB driver for the buttons, but cannot figure out how to program them, only how to change the color.

Finally gor to read all 145 pages, and I must say it is an awesome project and the project is just what I was looking for.
Although im not sure what computer (Raspberry pi, ODROID-X2,..) I will be using, I know what case and screen Ill be using :)
I would like to order a HDMI full kit soon, but will it include the button side board?
Hello everyone, Raspberry Pi user reporting in. I found this forum and thread while I was waiting for delivery from Derrick. Today I got the parcel, connected the screen to the controller board and managed to hook my raspi to it through HDMI input.
In case there are any raspi users, my settings (/boot/config.txt) are as following:
hdmi_group=2 # DMT mode
hdmi_mode=14 # 848x480 @ 60 Hz
The screen works okay, touch works as well (Linux recognizes it as a standard mouse, though I think it needs to be calibrated a bit). I couldn't manage to make raspi to switch to 800x480 resolution. Playing with framebuffer sizes and overscan values got me nowhere. Apparently raspi's firmware doesn't support this resolution, but I heard they will include support of arbitrary resolutions in near future. The best I could get is 848x480 shrunk into 800x480, so horizontally pixels are not aligned and appear blurred. I drew a test picture with 1px thin horizontal and vertical lines to see how it appears on the screen. As you can see, the horizontal lines (top middle and bottom left squares) are clearly visible while vertical lines and dot grids are blurred.
Now I have a little problem. After approximately 5 minutes of work an 1px thin red line appears at the very bottom of the screen and black interlace lines start to rise from the bottom. These lines appear only on color pixels, black and white rectangles are unaffected. The interlace gets as high as 80-90 px from the bottom. These effects don't appear instantly but rather slowly grow withing several minutes.
I though the problem was the signal from raspi, but then I switched to AV channel with no signal (with blue screen option on) - both red line and interlace appeared on the blue screen. When I let the screen cool for a couple of minutes (with controller board running) and then turn it on, the effects disappear. Anyone else has this problem? Also I would much appreciate advices as how to get native resolution on raspi.
Update: Apparently the lower part of the screen where these effects appear gets very hot. Maybe the problem is in my power source? I'm using 12 V 2 amps adapter.
I discovered why I cannot program the Left Panel HID buttons, it appears they are incorrectly mapped to different functions. I discovered when I program Mute it stores Play/Pause and when I program Volume Up, it opens Media Player. Programing blue buttons gets green, program green and get no LED at all, program red and get purple, then program white and you get red.
Derrick, can we get an updated version of the USB_HID.rar utility with correctly mapped buttons?
Sorry for the late reply. due to the hurricane Sandy, we lost power for almost two weeks, and runs on battery with very limit internet access every day.
Thanks for electricians from all over the states & Canada to help us out, we finally got recover! :)
