Okay guys. Just a little query here. Im rather new to pi and such but ive got myself involved in a project. Im making a gameboy like device with my pi. I have all the things I need except my screen. As this project involves use of gpio slots I dont have many left for a regular touchscreen... As I wont have an abbundance of gpio slots left for a screen I will need a screen (Preferbly NOT touchscreen) for this. Any suggestions?
(If possible. Try and make it of ebay. If not thats fine.)

Re: New screen?
Well the screen is kind of important to the project. I'm surprised that this wasn't given a higher priority from the outset.
What do you have connected to all those GPIO pins? Also you don't state which model of Pi you are using.
Another thing - the different between using a touchscreen or not, for most display boards is only 2 GPIO pins.

Re: New screen?
Ah okay. Sorry bout that.
My pi's a b model. I didnt want a screen tgat used gpii becayse half of them are already ebing taken up by my controller pcb. I dont want a touchscreen one because itll be unnecessary as I wouldnt find a use for it. Ive come to the understanding that I might have to use gpio. Is there any screens that only take up a row of gpio slots or come with a gpio extension?

Re: New screen?
Most 'gpio' displays will use the SPI bus pins plus a few 'general use' pins. Which pins does your expansion board use?
Of course you could switch to a B+ or a 2B and that way you have more gpio pins to play with.

Re: New screen?
Eh yeah... about that... kinda awquard really because the board occupies different scattered gpio slots that arent bunched together. This is the list. (Sorry if I write it weirdly) gpio 25 . Gpio 9. Gpio 10. Gpio 17. Gpio 23. Gpio 7. Gpio 8. Gpio 11 And any GND (as the board it a Common ground one)
