TLC59108 Sample Software

Isn't there basic sample program of some LED illumination patterns of TLC59108?

    TI does not have sample code available for this function.  The datasheet provies the required timing for driving the IC.  Each customer must implement the required timing with their specific microprocessor.

    I understood.

    In other LED drivers in the past.
    I saw the case of not able to operation correctly with order of register setting flow. The order had not been described to the data sheet.

    Therefore, I wanted a standard flow of the register setting that became the most basic, the illumination pattern of LED, and the setting example.

    Thank you.

    I second the request it would be nice if there was a sample or even a script that showed how to setup things, reset using standard i2c-tools (i2cset). There must be someone in TI that has already done this to test the device, no?

    I would also like to see some sort of scripts, even if it is just Psudo code.

    It would also be helpful to see some design schematics, possibly a reference platform to use when developing with this chip.

    I'll see if I can find someone that has some more info for this request.  If someone is able to support this request, they will reply to this thread.

    Has anybody gotten this thing to work?

    After wasting a couple of days with this device, I'm starting to wonder if there's a bug in it. I've tried many possible configurations, including ones that work with tlc59116 (and modified to account for the tlc59108 datasheet) but nothing... If TI does not provide more info, sample diagram and i2c commands specific to this device that are proven to work, then one can conclude that there's something wrong with it. Other people have requested that info before and noone has helped. Why is it even offered as a product?

    Marin,

    I am sorry you are having so much trouble.  There are customers using this part successfully without reporting issues.  We unfortunately do not have any source code which might help in debugging the problem.

    The IC does perform to datasheet specifications and will respond properly when driven per these requirements.

    I suspect you have tried more than one IC just to be sure, correct?

    can you provide a sample code just to ON-OFF the outputs of tlc59108 ? there should have been a simple example in the datasheet which will show how to write the driver for it, which registers needs to be configured first etc.
