Hey Guys,
I am running the 2.8 inch Adafruit touchscreen shield on my Raspberry Pi Model B+. I have the retropi image installed which is a build on Raspbian. After following the instructions
https://learn.adafruit.com/adafruit-pit ... stallation
I have got the RPi to display on the TFT shield. Startx and console displays on the 2.8" TFT but I can't get retropi to open up on the TFT,it still pops up through the HDMI port.
I have tried "FRAMEBUFFER=/dev/fb1 emulationstation" at the console, but after executing it retropi loads through the HDMIport.
Maybe someone can help me?
Regards
Michael D

Hey,
After some reading it turns out that the retropie project uses OpenGL for most of its emulators. The FRAMEBUFFER method apparently doesn't support OpenGL so it just won't work.
But of a pity.

I've found this post on the pi forums http://www.raspberrypi.org/forums/viewt ... 67&t=58952 which discusses the same thing. They use this https://github.com/tasanakorn/rpi-fbcp utility to copy the framebuffer. Only issue is it may be slow.

Re: 2.8" TFT Touchscreen Raspberry Pi and Retropie
Which Raspberry Pi model do you have?
Which model of Adafruit display?
Which SD card image are you running your Raspberry Pi?
The fbtft wiki may have some info that would help. (fbtft is the Linux kernel driver that allows the Pi to use small LCDs).
Framebuffer mirroring
MAME

Re: 2.8" TFT Touchscreen Raspberry Pi and Retropie
I'm using a Raspberry Pi 2 with the capacitive touchscreen 2.8" LCD from Adafruit (product ID 2423). I'm trying to install the screen using RetroPie (standard install). I've been following this guide (https://learn.adafruit.com/adafruit-pit ... stallation) but I keep getting errors as early as the part entering (curl -SLs https://apt.adafruit.com/add-pin | sudo bash)

Please try adding the "-k" option:
curl -kSLs https://apt.adafruit.com/add-pin | sudo bash

Re: 2.8" TFT Touchscreen Raspberry Pi and Retropie
That seemed to allow me to continue with the steps. Thank you!
However now all I get on the screen is a blinking cursor for the console. I used the easy install on a Retropie image. Would that make a difference for my install?
