    Kind of like saying HD44780, if it were an alphanumeric LCD.
    Does that help you anwer the question?

    You mean the one that said
    ... graphic LCD (KS0108B circuit)
    back in Aug '06?
    Things could've changed since then...

    Why ASSUME it's changed.

    He replied to a thread about a KS0108.

    No further information was given.

    Maybe he has a KS0108.

    You've done GLCD's before.
    Got anything for F1CHF?

    No further info was given...that's what I'm thinking...18 month old thread brought back from the dead for ????????
    Seems like one of the hotter things going these days are those Nokia color LCD knockoff boards and displays from Sparkfun. I'm having a ball with mine. Standby on that one. I'll have a LOAD of PBP code posted for those soon...ASCII character set in eeprom, text routines, semi-assembly printstr type functions, graphic functions (circles, lines, boxes, rectangles, shading, bmp conversions/importing semi-sorta like what you're doing with R.B. 1-bit sound routines, etc.etc.etc., crazy stuff).

    Code for the GLCD...Not that particular controller...and I can't think of what that one website was that had a bunch of sample code... I think the 122x32 GLCD code I posted awhile back is similar but didn't want to suggest 'cause I'd probably end up rewriting it completely to fit, or it just wouldn't work altogether.

    Compsys...Computech...something like that...sold Serial GLCD's I think...

    If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

    Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

    Well, yes and no. This is the one that I'm talking about:
    http://www.sparkfun.com/commerce/pro...roducts_id=569
    That's the one I've been messing around with the code for.
    The hookup boards aren't very cheap ($20 each), but the LCD's themselves can be found on eBay for less than $20...$40 total...and the code, practically free once I get it put up here, except for the pain in learning how to work it...

    Default How to use a GLCD display

    Thanks for coming back
    I didn't see that this thread was so old !
    It is the first time for me with GLCD display
    I have uploaded the PDF, is it suffisant to find which kind of controller it uses ?
    I hope so ..
    Tell me if I am right ...
    I have a process that fill a variable "toto" with a value (let say H for HELLO as a numeric value, because in PBP we can't handle alphanumeric)
    Through a Lookup table (as described in this thread) I will be able so feed a table
    with ROW1 to ROW7 ...(for example)
    I just need to send thoses rows to get the character displayed ?
    That would be nice, is to get a Sub routine (like LCDOUT) and just jump to it with
    the character fill in "toto" .. I am right or outside my shoes ?
    thanks in advance

    Hi, François

    On my side ... I've got a turnaround ...

    using a dedicated PIC just to care of big GLCDs ( 128*64 or over ). as it needs some ( LOL ) memory and time to write the whole screen ...

    The project was published in EP issue 279 ..., allows a 9600 Baud serial transmission from the PC or a Pic and the use of simple commands for classical shapes ( point, circle, box ...).

    If you want, I'll post you a copy of the full project ( no more downloadable from the EP site ) ... and "THE" SlotH ( Petter) listing.

    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    You are fairly close in your thinking...
    I don't remember the thread, but there is one floating around here that deals with that 122x32 LCD that I whipped up some PBP code for, including a fairly robust font table.
    Looking at the attached datasheet, with a few changes, it should be easily adaptable to the 128x64 LCD you are talking about (change the maximum's to 128x64 instead of 122x32, change the maximum X,Y for characters from 20x4 to 21x8, all characters are 5x7(6x8 with seperator), and some other minor timing changes.

    Here it is...
