    I am trying to use this chip HI-8010P-03 to drive a 1x5 LCD. I found the datasheet but I am not sure how I should connect it to the microprocessor in order to display data on the LCD. I will be using a Picaxe 14M2 processor.
    I will upload the datasheet in the next posting since the system apparently allows only two file uploads per post.

    As an option, there are PICs that have built in LCD segment drivers.

    Yes, but in this case, the LCD and the driver chip are mounted in a PCB and I can't separate them.

    Ah, okay.

    You shift in 38 bits of segment data by putting the data on the DIN and then pulsing ~CL low then back to high for each bit. After the 38 bits have been sent, you pulse LD high then low to transfer the shifted data to the output latches. Quite simple, really.

    Thank you Bob, I'll try that.

    I appreciate your help.

    It's all right there in the datasheet, but it does take some experience to read them.
