Thanks so much for your answers.

The idea it's to use one Atmega for the screen and control panel interface (input buttons) and another ATmega for the motors and internal machine I/O.
So with the two ATmega I want to create a NC control system for machines.
And NC control it's like a CNC but closed, you don't have the ability to send G code outside, it is all pre-programmed.

I was looking also at the matrix LED displays, but even it can show a lot of text, the screen is too small.

Given you are thinking of two separate controllers now, you might think of something like an Android tablet to do the I/O, and connect up with your motor controller via bluetooth or maybe a wired approach via the USB port.  Looking at the Android play store on my phone, I see quite a few options that are free or fairly cheap that would allow you to control an Arduino without having to learn to Android programming.

Or you can add a wifi shield, and have the motor controller export a web site, and just use a browser on the tablet/phone/pc.

I was thinking in something like that:

I don't know if it has the controller/buffer integrated, for what I read yes, but I don't know at what level or if it is useful, I'm not an expert on this matter. XD.


That particular module has an SSD1963 controller with built in 1215KB framebuffer - see datasheet for controller: http://www.allshore.com/pdf/solomon_systech_ssd1963.pdf - so it is easy to interface too, relatively speaking.  The controller is mounted on a separate board to the display itself and will be sending digital VGA-style signals to the integral display driver chips.
