Making a 4x16 LCD from two 2x16 LCDs

[Spanish_dude]

Is it possible to make a 4x16 LCD screen from two 2x16 LCD screens ??

I have two 2x16 E-Blocks and though about making it a 4x16 LCD.

Hello,

Yes this is possible though you will still need to use two LCD components in Flowcode.

You may even be able to pair up the data lines so that both LCDs run off the same 4 data lines you may even get away with commoning the RS line too. The E data pin will have to be unique for each display.

Hmmm...
I wanted to use one LCD component for that, but I forgot about the E pin.

So that's not possible unless I use 2 LCD comp.

Thanks Benj.

(Btw, have you received the gLCD E-Block ?)

That's correct.
A similar thing was done here:

Hello,

Yes I have received the E-block and we are sending out a replacement for you. Putting pressure on one side of the display made it function correctly so I think the ribbon cable to the display must have become slightly damaged.

Yeah
Thanks Benj.
