Hello guys

The last days i have been putting together a rgb led backlight solution which i want to connect it to my revo3610 running Xbmc live pre Eden.

I wanted to use this guide: http://amblone.com/guide/ but since i got common cathode RGB led strips i had to use this circuit:


Everything is up and running and I (think) i wired it correctly according to http://code.google.com/p/boblight/wiki/Compiling:



All the programs that i write in arduino work great and the amblone program in windows (with the amblone pde) also worked, but that is not an option for what i want to do. )

I followed the guide for a arduino mega but the colors are all wrong. When i run the test commands (for example command boblight-constant FF0000) i get two different colors on only two led strips.

Since i don't even get the right colors out of the test i wanted to see if someone either had this problem before or saw right away where my mistake was.

Ps i remember something about a boblight branch of xbmc. Is that still alive and are the pre eden builds of that?

Thank you

show your boblightd.conf ... works here with a custom pcb ...

and as far as i can see the firmware for ambalone and boblight are not compatible. So if you use the ambalone firmware it won't work with boblightd ...

I am using this boblight.conf which is basically this one with a changed output from /dev/ttyACM0 to /dev/ttyUSB0

Then i programmed the arduino with this

When i was trying it with amblone i uploaded the amblone pde file, but have now uploaded back to boblight_arduino_pwm.pde

Try "boblight-constant FFFFFF", if all leds are on, then the colors in boblight.conf probably aren't mapped to the right channels on the controller.

Thanks for the answer

I seem to be getting only 6 channels

I´m going to fiddle around with the settings but if someone knows what my problem is it would save me a lot of hassle

Don't know why, but my arduino was not identifying it self as AVR_ATmega1280 so i took the if line out of the code

Thank you

Looks like a solution. But its not the arduino which identifys. This setting is checked during compile time. So maybe your arduino IDE was set up with the wrong arduino type...

Hi Steini,
Did you ever get your setup working? I had a similar problem, but just solved it. I was using the mega2560 and also thought that I had to take the mega1280 reference out of the code, and so defined my outputs as [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] directly without the 'if' statement.
