Adafruit 3.5 tft

Post by Warmbadger »

Wanted to throw out a request for the adafruit 3.5 tft display. Spent my weekend trying to get it to run with a variety of install options but always came up empty.

Dietpi is very usable without the feature but it sure would be cool to have it all display on the tft.

Thanks

Did you try it with RPi or which device?

Add me to the list, in my case I use the 2.8" TFT from Adafruit with my Raspberry Pi 3B+. I managed to get through the Adafruit driver install by doing the following as root:
  • First I went through the adafruit-pitft.sh script and replaced references to "/home/pi" with "/home/dietpi"
  • Next I installed setuptools:

    Code: Select all

    sudo pip install -U setuptools
  • Then I installed python-dev:

    Code: Select all

    sudo apt-get install python-dev
  • When I started running into issues during the PIP install of the driver, I was able to actually get through it with no problems by first installing these common dependencies:

    Code: Select all

    sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
This allowed me to get through the install script without any errors. However, when I reboot, I'm still not seeing anything on the TFT.

Any pointers on how to get this resolved without having to switch away from Dietpi? I really love this OS.

Hi I am having the same issue.

I have run the TFT install script the when I reboot, it is just not showing on the TFT screen. Screen is on but completely blank. Anyone figure this one out?

Add me to the list. Got an RPI B up and running on Dietpi this AM. Cloned the git from Waveshare and ran the driver install but no love.

Okay found the script: https://raw.githubusercontent.com/adafr ... t-pitft.sh

Outdated and adds forcefully an outdated Raspbian mirrordirector that is changes by RPi packages again. Tailored for Raspbian. Strange that it does not add the build requirements then. I'll see if I find time to contribute to it to make it better compatible with non standard Raspbian distros. If anyone wants to help, is welcome of course :).

Ahh btw is this dtoverlay "pitft35-resistive", shipped with RPi firmware, not already functional?
