    Folks,
    When I was in Shanghai recently I found some very cool RGB LED
    ribbon lights. The ribbon is populated with one 16 pin surface mount
    chip every 3cm or so. Each chip has 2 high brightness RGB LED's hooked
    to it. The chips are an HL 1606 which I believe is made by Wuxi ASIC
    corp in Wuxi province of China. Unfortunately I have been unable to
    find a spec sheet on this chip despite many days looking. Based on
    scope observations, the signaling is quite complex and contains
    color, ramp and brightness info in some complicated frame format on a
    5 wire interface which I believe is SPI. Does anyone know this
    chip.. or knowwhere I can find a data sheet and perhaps some app
    notes ? I'm hoping to clone the simple PIC based controller I bought
    with it. Thanks very much for any help or leads...

    I was recently working on an SPI interface and debugging it with a scope
    wasn't cutting it. I borrowed one of these
    http://www.tech-tools.com/dv_dv1.htm and it showed me the problem just
    about instantly. If you just want to reverse-engineer the interface,
    this may help. If you don't want to spend the money on that box, the
    other way is to get an old junk PC, wire the interface to the parallel
    port, and write a DOS program to watch the input lines on the port.
    Have you tried putting the chip in a programmer and reading back the
    program? (Or did they activate the settings that are meant to make it
    hard to read the program out?)

    Standard disclaimers apply; I don't get money or other consideration
    from any companies mentioned.

    There are a series of project called "disco dance floor",

    were engineering students built a Color LED dance floor and bar top.

    The schematic and code are available.

    I see it's a pretty old topic, that's why I try to revive it. So has anyone any documentation, pinout, communication, message format.... anything about this ICs?

    I have the controller for them but I don't like that you have to choose from the predefined modes, not being able to build anything custom.
