RetroPi 3 on Rasbperry Pi 2 AND pitft 3.5 LCD
For the life of me I can not get my Adafruit piTFT 3.5 LCD (480×320)
working… I had it working before with previous version of RetroPi.
Anyone? If you do have this working, PLEASE reply with a link with exact instructions you used. Every page I followed doesn’t work.

Did you get this working with RetroPie 3.0?wilsonbParticipant10/26/2015 at 04:44Post count: 17
No, I went back to a previous version of Retro Pie and have it working nicely (mirroring LCD & HDMI out at same time).
Have not tried it in a few months. The latest version avail when I posted this, broke things/ think it used the wrong kernel. No way could get it working.auswearParticipant10/26/2015 at 04:57Post count: 65
Damn… so I guess it just comes down to retropie?wilsonbParticipant10/26/2015 at 05:02Post count: 17
Do you have the exact LCD I have with Raspberry 2 ?
Use an older version of Retro Pie, pre 3
I can boot mine up tomorrow and let you know what version I got working.
Matter of fact, can give you most of the files to get it working.
There is that automated script for LCD setup from Ada fruit (google).auswearParticipant10/26/2015 at 05:13Post count: 65
Not yet.. just investigating an LCD I can use in a large scale project. I would prefer to use 3.0 but starting to realise that may not be possible at this stage.
The files would be fantastic, thank you!goldenzippoParticipant10/27/2015 at 13:51Post count: 1
I’m having a ton of problems also. I’m not even able to run the first couple of lines of the tutorials without having errors thrown at me.
curl -SLs https://apt.adafruit.com/add-pin | sudo bash
sudo apt-get -y install raspberrypi-bootloader
sudo apt-get -y install adafruit-pitft-helper
I got the curl to run by just adding the addafruit repository minus the add-pin but I feel it’s causing me to be missing somoe things I need.
rspberrypi-bootloader seems to install fine
the pitft helper only pratially installs & throws a size mismatch error so I can’t even run the helper.
Tried editing the config without the helper through the instructions but that didn’t do anything either.
I’m using a totally generic 3.5 touchscreen I found from China.
Thanks for the heads up on previous versions working. I think I’ll try setting it up in an older retro version & then update if I get the screen working.wilsonbParticipant10/27/2015 at 17:05Post count: 17
goldenzippo , the Adafruite script will prob not work with your generic LCD. You would need specific drivers for that LCD. What I posted was for Adafruit 3.5 LCDauswearParticipant10/27/2015 at 23:05Post count: 65
I’ve just received a 2.4″ adafruit screen and I’ve followed the below guide but keep getting a white screen. I’ve checked solder joints and they all look ok, and have tried installing the kernel on 2 seperate installations of Retropie 3, but keep getting a whitescreen / backlight.
One thing I noticed that when it switches from framebuffer to the emulation station screen (As I can see this on my monitor via HDMI), the LCD quickly turns black and then goes back to white. I’m guessing this is trying to initialize the driver?
Does anyone have any tips to get this working?wilsonbParticipant10/28/2015 at 05:17Post count: 17
What version of Retro Pie are you working with?auswearParticipant10/28/2015 at 05:28Post count: 65
3.0. Others have managed to get it working and I for the life of me can’t figure it out :\
