I have the Uno, and I want to drive 4 LCDs with just the one board. I already saw the topic from before which included driving 4 LCDs at once (@ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265969050), however the LCDs I'm using are rather different from the ones used in the example: I'm using the Varitronix VI-401-DP 7-Segment display, which seems to require a few dozen connections for just one. Would I still be able to drive the 4 of them with the single board, or would I need to get different LCDs?P.S. This is my first time programming displays, and I'm still working out the kinks just in terms of the right display to get, as shown with getting the LCDs before I had settled on a microcontroller (I had a good reason at the time; I just forget what it was ).
it works quite nicely with the arduino.
Each one has an Enable pin, which selects that LCD to be handling the information on the data bus. The LCD's have their own memory and all the messiness, all you need to do is write the data, there's even simple Arduino libraries to handle it. All the data lines can be connected on all the displays (I'd just use 4 bit), because only the display with the Enable active will care.
Your picture is a bit strange. Either it's flipped vertically or it has connections below the display.
