Anyone have thoughts on this that might help me?
I'm planning on some Renard boxes for my display later this year. 2013 will be my first year. I have a bunch of lights bought on clearance, but won't be doing any pixels for the show (might get a few to play with, but thats it).
In the meantime, I am thinking of making up a "live demo" board to test/play with. My idea of this is that I can make a mockup of the setup I will have (something like the preview, but with hardware, not just an image). It will also be a way to consider adding in Arduino controllers to the setup for other thoughts for the show if it works well (things that won't be using big power AC controllers).
So my thought is this:
Drive it with an Arduino Uno. Setup with RS485 and have the Uno coded to read Renard protocol. For outputs, chain together TLC5940s as output (16 PWM channels per chip, chainable). By doing this the Arduino can "act" like Renard hardware and I can use single color LEDs to simulate my setup.
This is a playground for me, but may expand into "real" show if it works well.
So.... Am I nuts? Is this silly? Is there anything that I've missed that someone has done (I think the Renard has been done, and the 5940 library is out there - so much of the guts is ready)...
