tomcody Posted March 28, 2006 Posted March 28, 2006 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.
Guest Posted March 28, 2006 Posted March 28, 2006 Hi Tom - You are DEFINITELY following my guide to newbies:http://www.midibox.org/forum/index.php?topic=3650.0Or 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?Moebius
tomcody Posted March 28, 2006 Author Posted March 28, 2006 ;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.
Guest Posted March 28, 2006 Posted March 28, 2006 Hi. ;)"So close - so far away" - the LCD driver is compatible, but the pinout is definitely NON-standard.. :PYou might want to try google again for the datasheet.. You got the LCD type number/code from the LCD board right.Moebius
Guest Posted March 28, 2006 Posted March 28, 2006 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.Moebius
stryd_one Posted March 28, 2006 Posted March 28, 2006 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?
