Using GPIO for both control and display.

I wonder if it's possible to use the GPIOs for both all the controls and a display, because I seem to have purchased this:

https://www.ebay.co.uk/itm/7-TFT-LCD-To ... 2749.l2649 which I think is designed as an Arduino shield?

Any help would be great! This is my first electronigs and GBZ project so if anything I'll purchase a BW screen which might make things simpler.

Yes it's possible. That's what we're doing on the mintyPi. :)

I can only find one library for the spfd5408 controller which is aimed at Arduino boards ;/

I'm not sure about that particular chip, but if you're using something like an ILI9341 there are enough pins for both the screen and an SNES-style button layout.

I will look at any supplementary documentation that comes with it to see if it's manageable, otherwise my student loan comes in next week so might as well get a new display :) Thanks for your input!
