I posted this in the Pi forums, I realise it should probably be here, because ... well, it's product support!
I've just attached my DOTHAT for the first time since getting it for Christmas. I've followed the lib install guide, and fired up backlight.py.
It runs without complaining, but the backlight doesn't come on. All I can managed to get working is the bars (these just scan up and down in a loop) and the LCD shows "Such Rainbow!".
The output for i2cdetect -l is:
i2c-1 unknown 3f804000.i2c N/A... and the output of i2cdetect -y 1:
0 1 2 3 4 5 6 7 8 9 a b c d e f

I have tried this on both Wheezy and Jessie with the same results.
