LP5569: Documentation

Part Number: LP5569

I'm attempting to use the ATtiny417 to program the LP5569 to drive two RGB LEDs. I haven't used the 5569 (or any other kind of other driver IC) in the past, and was wondering if there was some sample code or more documentation available anywhere. The datasheet is a useful reference, but it does not have much in the way of explanation on usage of the chip past command library and communication protocol. Thanks for any help you guys might be able to give!

  • 0904 lp5569_i2c_master_w_multibyte-master_code_MSP_EXP432P401R.zipHi Graham,

        I upload the sample code for the reference, could you open it with CCS (TI MSP430 TOOL)?

    Thanks!

    Thank you for the code! Super helpful with my implementation.

    Hi Summer!

    In the datasheet for the LP5569, it mentions a command compiler for simple ascii commands. For example, ramp 0.6, 255;

    Is this something native to CCS, or when communicating with the driver do I feed it a series of hex values which correspond to that string?

    Thanks,
    Graham

    Hi Graham,

       Could you download the GUI for the below link since the compilee (lasm.exe) is in the GUI?

    Thanks!
