Quoted from ecurtz:The board only has 6 available PWM outputs and those are being used for the left and right ramps. If you were willing to share colors between the ramps or between one ramp and the topper you could split the signal.
Alternately there are four open and usable digital pins. That's how I was doing the synchronized under cabinet light demo. That was driven by a board that uses a simple serial protocol (the shiftbar from http://www.macetech.com) so it could set the left and right strips to match the colors of the ramps.
I have no idea what is in those little self contained remote controlled RGB lights like the pinballtoppers.com speakers use. It might be trivial to connect to them, but it's more likely to be a single unmarked chip covered with epoxy.
Most of the RGB LED's appear to have a standard 4 wire hook up connects with the RGB controllers. I haven't used them before so I'm not sure what kind of signal is on those 4 wires. I was assuming it was using the same PWM technique that you're driving the ramp RGB led's with.
So will the 4 digital pins you used to sync the under cab lighting to the ramps be available on your finished mod or is that something you were just playing around with? I would think you could drive the speaker lights with the same kind of strips (just smaller size) used for the under cab lights.
The hardest part of all this is decoding what the game is doing to know what colors to make the ramps so they sync with the game modes. Since your mod is already doing this, having the ability to drive additional lights (under cab, topper, speaker lights, etc) should be easy to add on. If your mod could do this then it would surpass the real Tron LE for its light show possibilities.
