About dimming the background, i think it's possible add a jumper to enable/disable the dimming as you need.
Year the dimming can easily be turned on/off, but I would prefer a solution with black outlining.
Personally I prefer to have a pot to change reference voltage or bias voltage, but you can make it as you like. You might want to change the fast PWM to 9 bit for better accuracy.
At the moment the code is a mess. I will clean it a bit and upload.
Have anyone successfully used the code? I guess most of you guys are using NTSC?
