Thanks to all of you for the help, sorry I haven't been really present in my own thread lately, I've been busy with some other projects for Christmas presents. Here is how the project stands thus far. The project is working well as a visualizer using the TLC5940, the only thing that needs some work is the overall linearity of the output, I have a plan to create use a custom scale that I made dividing the tubes into 128 parts and to create an array of the representive numbers for each segment. then using that number to get accurate 128 segment representation. I'm basically using Jeff Malins purposed approach as of this moment and when i plot the points it looks somewhat like a Power Curve. Does my plan sound reasonable? Or does anyone have any other ideas to better the linearity, perhaps different value resistors?? ? Again thank you to all of you who have helped me greatly in this and other projects, It's quite a great blessing to have access to such a pool of knowledge.
