PiTFT with Pi-hole not working

by jasonaylward on Thu Oct 24, 2019 10:52 am

Hi. I recently bought the Pi-hole setup and I seem to be having trouble getting the PiTFT working. It's obviously getting a text from the pi but it's all broken up and unreadable.

I saw one tech page about some little black tags being pushed in all the way. It underside of the PiTFT appears to look just like it's supposed to.
Any ideas?

Which Pi are you using and what version of the operating system? Can we see a picture of the back of the display?

It's the Raspberry Pi 3, Model B using the most recent version of Raspbian Lite.

Thanks!

Sorry. Didn't realize it was upside-down until it was too late :)

That's OK. Check the clip on the left side of the cable in the picture to make sure it is tight. If that does not fix the problem send a note to support@adafruit.com with a link to this thread and they will get you a replacement display.

Hi Franklin. I got a new PiTLT in the mail this week and I'm seeing exactly the same noisiness on the screen.
Is this a problem with these units?
I've attached photos of the new unit plugged into the raspberry pi running pi-hole.
Thanks

hiya could be something changed in our setup code - can you re-run the pitft setup script and post a screenshot/paste text of the output?

FWIW - Installer script seems to be OK. I just burned fresh copy of 2019-09-26 Raspbian Lite, booted on a 3B+, and ran through script:
https://learn.adafruit.com/adafruit-pit ... -install-2
Select 1 for screen, 3 for rotation, YES for show console, reboot. Worked fine.

@jasonaylward Were you following this?
https://learn.adafruit.com/pi-hole-ad-p ... ation-4-10
which shows setup for a different screen.

Sorry for the delay. I was away from the computer over the weekend.

@carter, yeah, Those were the directions I was following but I didn't realize it was for a different screen. I wasn't paying attention to screen dimensions.
I'll try to re-run the config and see if that helps. I'm guessing that was the problem all along.

Update: that was totally it. I had the wrong display.
Thanks. And I'm really sorry you all had to send out a new PiTLT. It was totally not my intention.
Thanks again.

Oh well. At least now we know. Glad it's all working.

I just set up a pi-hole with the same kit and had the same problem for the same reason--I didn't pay attention to which display I had when making the selection during PiTFT software installation and just blindly followed the wrong guide, selecting option 4 instead of 1. Thank you very much for documenting the problem and solution in this thread. I just re-installed the software and selected display option 1 and now everything works perfectly.

We updated the guide (a few days ago?) to clarify the specific display being used. Hopefully that'll help make it more clear what options to pick for the TFT that comes with the kit.
