    I am having a lot of bad luck lately. Local electronics stores REALLY suck here...

    Yesterday I bought an LCD display "Parallax 4x20 Serial LCD, 27979", when I got home and open the package it was a display but a completely different model, with only one line.

    I went today to return it, but they did not have replacement, the only other LCD they had was a HC16201 (only 2 lines, but it's cheap, so I bought 2 of them)

    I am trying for HOURS to find the data-sheet for it, but the only thing I find is this one page PDF:
    http://www.britestone.com/shop/upload/DN/LCD/HC-16201.pdf

    I looked for a similar LCD, and found this: HC16202NY-LY

    The data-sheet gives more info, but I still don't see what data to send to it in order to display the text I need... I don't see a list of commands, or a ASCII chart, like I usually see in LCD data-sheets.

    Can someone help me find out how to use it ?

    PS. I will use a PIC microcomputer to interface with it.

    Can you read which driver ic is on board? I cant tell from the datasheet.

    Hi retched,

    This is my first time to try to get an LCD to work, so I never thought that searching for the IC part on the back of the LCD will give me results. But I was wrong, and thanks to you now I found what I need.

    I found the data-sheet here:
    http://www.sparkfun.com/datasheets/LCD/HD44780.pdf

    Also, I am using mikroC to program the microcontroller, and apparently mikroC comes with a library that supports this IC HD44780.

    So, I'm all good now... thanks
