compatibility problem with waveshare 3.5ich ips lcd

[mvoss96]

Hi, first of all thank you for your project.
I was trying to install octodash to use it with an wavesghare 3.5inch ips touchscreen (https://www.waveshare.com/wiki/3.5inch_HDMI_LCD)
However it seems like there are some compatibility problems:

I startet with octopi stretch lite on a raspi 3 then installed octodash which woked perfectly however when i installed the waveshare touchscreen driver octodash does no longer work.

the commands for the waveshare driver were:

git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
./LCD35-HDMI-480x320-show

now i only get the console screen and it says:

sadly my linux knowledge is not good enough to find the error

Hmmm I don't have a waveshare display so I can't really test anything. The error indicates that you have some issues with your screen rather with OctoDash though.

Some things you might try;

• Could you start ratpoison / octodash manually?
• Open an issue in the waveshare repository and ask them whats going on, I think the issue lays on their side
• Rerunning the installation script

Hi, i have solved the issue. The waveshare script appears to be truely broken. i copied all settings manualy in the corresponding files and now the touchscreen works flawlessly.

The UI really is very beatiful.
However i would have one suggestion: Maybe there could be a bit more feedback on touchscreen input so you see when a touch is registered.

thank you for your help

[UnchartedBull]

Great that this is working now. Going to close this issue for now.

would you be so kind and open a new issue for the touchscreen feedback? I've only seen in the control screen that the feedback is quite little ... Please open a new issue and elaborate a bit further which screens you would like to improve.

I just wanted to add (it might help someone) how I fixed a problem with my Waveshare 12287 3.5inch RPi LCD (B):

I installed a fresh OctoPi 0.17.0 and OctoDash using the script and enabled Console auto-login however X would fail with the error message "Failed to load module "fbturbo" (module does not exist, 0)".

The solution is simple :) Just install "sudo apt install xserver-xorg-video-fbturbo"

BTW @UnchartedBull, thanks for the beautiful UI, it looks great on my Ender 3 Pro :) https://imgur.com/a/EzcksY9
