Hey guys,
I was searching for a new project and thought of programming this calculator I have laying around with an arduino nano board. It is a Casio FX-87DE X calculator (here the official Casio link: this is the European website. I hope it'll work for you.).
I think my first task will be trying to get the display controlled by an arduino. So here's my question:
Is it possible to control this display just by an arduino?
The only thing I know about this display is that it's a 63*192 Full DOT LC Display.
Here are two images of the calculator's front and insight:
Of course driving the display is possible, because the simple chip in the calculator does it. But LCD displays have special drive requirements that include an AC signal. Look at that connector. Are you prepared to solder to it? Do you have schematics of the calculator? Probably not. So you're looking at a very, very complex and difficult project.
I doubt you’ll easily get the display connected - you could however simulate key presses with connections across the keys .
Not sure why you would want to do this , what’s the objective ?? If you want to drive the display the functionality of the calculator is lost , so you would better off just buying a display of some sort that is supported by Arduino .
