3.5inch driver not installing correctly #850

Hi, If you are using a Chinese 3.5" LCD - that used the model number XPT2046 - give up now. They simply do not work. I spent hours on this, followed numerous threads and lost more hair that sleep. Advice, buy a genuine 7" Raspberry Pi LCD, or one of the ore reputable brands. If you want a 3.5-4" then the HyperPixal4 is the best, if you can find one Best of luck.....you will LOVE it once you have it running Ray |

Hi Ray, thanks for your reply. Yeah XPT2046 is exactly the one i have:/ I had hope because i managed to get TouchUI working but i gave up after hours... I took your advice and just ordered a Hyperpixel 4.0 and a new RPi 4 :) Will the 4 perform better than the 3b+ or is Octoprint + Octodash far away from any performance issues? Kai |

I’m yet to get the HyperPixal - but many proper use them , and successfully- if you don’t mind the 7” screen - they are awesome Keep us posted |
|
You shouldn't notice any huge improvements with the Pi4 as the Pi 3+ is more then sufficient already. You can't have enough power though, so good choice! Closing this here for now thanks @K1W13D for providing the info. if you have issues with the new screen please reopen :) |

Hi, the Hyperpixel 4.0 came and is working:) I tried to google this information since 1 hour but can't find it anywhere. In Prusaslicer i also get only maximum feed speed rates. Maybe anyone can provide me this data. thank you! |
Hello, I had the same problem but I soldered all pins and it was working in the first test. |
Hi,
i'm an absolute novice in coding. I've been using a RPi 3 B+ with Octoprint for a while. Now i wanted to add a touchscreen with Octodash. I got it to work with TouchUI before, but with Octodash i have no luck.
I think the problem are the display drivers and not Octodash. Unfortunately i don't know anybody else to ask with this issue. So i hope it's ok to post it here.
I'm using this screen: http://www.lcdwiki.com/3.5inch_RPi_Display
(Yes you write that GPIO screens can be problematic, but i've bought it before i read your advice...)
After running "sudo ./LCD35-show" i always get this:

I tried "sudo apt-get update", "sudo apt-get upgrade", "sudo apt-get dist-upgrade", etc... multiple times. I also reinstalled (or at least i tried) xserver-xorg-input-evdev and man-db.
The guide on https://github.com/filipeflop/xpt2046-LCD-Driver-for-Raspberry-Pi tells to execute additional commands. After "sudo dpkg -i -B xserver-xorg-input-evdev_1%3a2.10.3-1_armhf.deb" i get:

Maybe you can help me with my issue.
Thanks in advance!
