Using an adafuit tft touchscreen for a gaming system

Post by MalMan35 »

I Basically want to make a game arcade where you can play games like super Mario bros, Dr. Mario, etc. I want to use the small adafruit tft touchscreen I got for birthday as the screen (I don't care about not using the touch part of it.) https://www.adafruit.com/products/1601

But when I read this
https://learn.adafruit.com/running-open ... t-displays
it said this at the top
IMPORTANT: recent updates to the Pi kernel & bootloader are incompatible with this guide — the hardware/software combination presented here DOES NOT WORK at the moment. We are working on a fix and will remove this message once things are getting along again.
So what I was wanting to know is if someone can help me work around this to get it to work. Some detailed instructions would be nice ;D

btw: I have already asked on the rpi forums but I thought I might get some better help here.

What you're asking for is a complete writeup for a problem we're still trying to figure out. If we were able to post step-by-step instructions here, we'd be able to update the tutorial and point you to that.

We make the display, but the Raspberry Pi Foundation writes the RasPi-specific parts of the OS. They change things from time to time in order to make the RasPi work better, and we learn about the changes the same day everyone else does. If one of their changes breaks some of our code, we have to figure out what changed, what's causing the trouble, and how to make our stuff work in a way that's compatible with the latest OS.

We're still trying to figure out how to make our OpenGL code work with the new kernel. But as Einstein once said, "if we knew what we were doing, it wouldn't be called 'research', would it?"

okay... I got it. It is just that when I got the screen for my birthday (back in march) it said the same thing and I guess I thought someone had figured it out by now. Good luck on trying to figure it out. I know I have no clue what so ever as what to do.
btw someone on the rpi forum said:

If you're running on Raspbian do
sudo apt-get update

to pull in the latest raspberrypi-bootloader package.

Edit /boot/config.txt (if using NOOBS use the recovery system config editor) and add
CODE: SELECT ALL
dtoverlay=pitft28-resistive
reboot and your screen should work. It will be different for things like OpenELEC & OSMC.
and I replied
So... If I install retro pi on my rpi that is all i have to do?

I'd suggest trying out the pre-built SD card from the Pocket PiGRRL project:
https://learn.adafruit.com/pocket-pigrrl/software-1

I'm not sure if that works on the Pi 2 (maybe), but should be OK on any Pi 1 variant.

This is based on an older kernel that plays nice with the screen. Whatever you do, don't raspi-update the system, this will break compatibility and you'll have to start over.

Raspberry Pi org is in the midst of big changes to the kernel, so it might be a while before the OpenGL guide is back in action.
