Cracked the Code
Posted by JEC on September 21st, 2009
After a couple hours work this afternoon, I can now communicate with the new discretely-controllable Asian RGB nodes (described below).
In a couple days the DMX and Art-Net interfaces should also be online.
Onward!

Hi, Great work on cracking those things. Is this for the HL1606 chip by any chance?

Actually, it’s not. I looked at a couple products using the ’1606, including those waterproof RGB strips. However, after further research I determined that the controller wasn’t appropriate for a ‘live’ environment.
As you may know, that controller can only hold a steady state in the 7 primary combinations of the three colors: R, G, B, R+G, R+B, G+B, R+G+B. All other color combinations are only transitory in nature. The controller can be told to fade from, say, red to green over .8 seconds. It then handles the fading / PWM driving internally.
But if you want a steady state mix of, say, 85% red and 15% blue, it’s impossible to achieve.
Since our goal is to control these nodes in real time, products based on the ’1606 were, unfortunately, eliminated.

Yeah, that’s what i was wondering if it was that chip. I had a bit of a play with the DM413 to create a similar thing, but to purchase ready made modules seems like a much easier solution especially at the price you suggest. Are you able to state the chip ?
