question about 2x32 LCD

[tomcody]

Hi everybody.

Can I use a 2x32 LCD on a midibox64???? if the answer is yes, how I connect it to the CORE??? this LCD has 20 pins. Thanks.

Hi Tom - You are DEFINITELY following my guide to newbies:

http://www.midibox.org/forum/index.php?topic=3650.0

Or do I say - You might be able to answer Your own questions if you provided the crucial information of:

A. Is the controller HD44780 compatible?

B. Do you have pinout of the LCD or the datasheet?

;D Sorry, but I have been looking for a datasheet or information about the pinout but I don't find anything. I think is compatible, it has a HD44780A00 chip. I have been observing the pins and seems that there are a few not connected to anything .... Can I do something to test it? Thanks.

Hi. ;)

"So close - so far away" - the LCD driver is compatible, but the pinout is definitely NON-standard..  :P

You might want to try google again for the datasheet.. You got the LCD type number/code from the LCD board right.

Or the new "Tip of the Week" section:

If You can't get datasheet for Your display, You can trace the connector pinout using datasheet for the HD44780 as a reference.

All pins but Vo (contrast voltage) (and possible backlight) are directly connected from the connector to the HD44780 pins.

By watching the controller pin arrangement and using conductivity tester of your Multimeter - You can figure out the pinout by yourself.

Hi Moebius, you've got over 1000 posts now! The forum says you are a MIDIBox GURU  ;D And that last piece of advice proves that the forum is correct. Very good tip! One for the wiki?
