Pi-tendo portable

Fri Apr 03, 2015 3:48 pm

Hi I am building a portable focused at RetroPie. I need help attaching controls, I think I will attach to the GPIO.
The controls I am making are.

. 3ds slider pad
. tactile switch D-Pad
. 6 general purpose buttons
. L, R, and Z shoulder buttons

I will also have a 3.5 inch screen. It will all be put in a modified GameBoy case. Any suggestions or links will help.

Thanks.

GPIO should be fine for all of those except for the 3DS slider, I'm not sure I know what you mean by that. However, if it has wires, it should be able to hook up to the GPIO. Just out of curiosity, what exact screen are you using and how does it connect to the Pi?

the 3ds slider is a neatly-designed analogue stick. I don't know what sort of signals you get out of it, though they'd be analogue too, I assume.
note: I may or may not know what I'm talking about...

I will probably use this guide. http://forums.modretro.com/viewtopic.php?f=33&t=8256

or this one. http://www.newsdownload.co.uk/pages/RPi ... stick.html

For the 3ds analog stick.

As for the screen well I will probably use this.

I am thinking that I will take off rca port on pi and solder directly, then use this guide

for power. Or I will wire to power circuit since I think this monitor turns off automatically when no inpuit is running.

Hello

how about trying this 3.5 inch tft with resolution 480x320 and working on 5 volts (no extra power source needed draws power from the raspberry pi header itself)

and directly plugs on the header of the raspberry pi
