Waveshare 4.3 DSI lcd screen: can't get the touchscreen to work with octodash #3938

Open borderline667 opened 1 year ago

borderline667 commented 1 year ago

What doesn't work? After the install. Octodash is showing up correctly, but I can't use my touchscreen it does not work, so I'm stuck at the HEY THERE welcome screen.

What did you already try? Tried 4-5 times to reinstall everything. Touchscreen is working I could test it. There is probably a stupid thing that is missing in my config.txt file :-(

General Information:

Here is my config.txt file. If someone could help I would reallly appreciate!

arm_64bit=0

For more options and information see

http://rpf.io/configtxt

Some settings may impact device functionality. See link above for details

uncomment if you get no picture on HDMI for a default "safe" mode

hdmi_safe=1

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

overscan_left=16

overscan_right=16

overscan_top=16

overscan_bottom=16

uncomment to force a console size. By default it will be display's size minus

overscan.

framebuffer_width=1280

framebuffer_height=720

uncomment if hdmi display is not detected and composite is being output

hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

hdmi_group=1

hdmi_mode=1

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

config_hdmi_boost=4

uncomment for composite PAL

sdtv_mode=2

uncomment to overclock the arm. 700 MHz is the default.

arm_freq=800

Uncomment some or all of these to enable the optional hardware interfaces

dtparam=i2c_arm=on

dtparam=i2s=on

dtparam=spi=on

Uncomment this to enable infrared communication.

dtoverlay=gpio-ir,gpio_pin=17

dtoverlay=gpio-ir-tx,gpio_pin=18

Additional overlays and parameters are documented /boot/overlays/README

(e.g. for USB device mode) or if USB support is not required.

I also have this problem, for what it's worth. I tried commenting out the drivers per this post, but that didn't work either.

ichibana commented 1 year ago

I also re-imaged the SD card back to a stock Raspberry Pi OS (not OctoPi) and confirmed the touchscreen works and responds to input in that state. So the hardware is known good.

borderline667 commented 1 year ago

ichibana: This finally worked for me! Remove this from your config file: dtoverlay=vc4-kms-v3d dtoverlay=vc4-kms-dsi-7inch and add this line: dtoverlay=ft5406

So basically, the steps are:

1-Install a fresh and clean OCTOPI 2-sudo apt update 3-sudo apt install -f 4-sudo apt upgrade 5-add this to your config file: dtoverlay=ft5406 and comment all other "dtoverlay" lines 6- Install Octodash

Let me know if this worked for you

ichibana commented 1 year ago

Trying now, @borderline667 ! I did come across this post which said something about that command being... out of date? I'm no expert, so read the post in that thread if you're curious. It's near the bottom.

That being said... I'll give it a whirl right now.

This is Interesting! I'm no expert as well and this screen gave me a lot of headaches. I now have wifi connectivity issue but the screen is still working well. It's still a work in progress :-)

@borderline667 where did you learn this arcane wisdom? Would love to read the source and familiarize myself with the context too.

ichibana commented 1 year ago

Hey @borderline667, you know what ended up working? Commenting out all instances of dtoverlay=vc4-kms-v3d driver. I thought I had earlier, but there was a line a bit earlier in the config.txt that also had this call. This is what was suggested in this thread, so I'll go back over there and comment accordingly too. I did not utilize the dtoverlay=ft5406 call. I would be curious if you can also achieve success without this line if you comment out the earlier dtoverlay text that is in the config file.

If anyone reading this can help me learn why removing the Waveshare-recommended drivers is what fixes the issue... I'd love to learn.

I'll try to do this in the next days. Not sure where I found that call, maybe here: https://community.octoprint.org/t/octoprint-octoscreen-touch-not-working/52493 I need to learn more on how linux commands work I guess

ichibana commented 1 year ago

Thanks for sharing the source! I’ll give it a read.

Are you having WiFi problems with octodash only or also your octoprint setup entirely?

borderline667 commented 1 year ago

Only with octodash. In the meantime I have switched for another router (eero 6+) so I'll give another try to see if it fix my new issue. But octoprint itself worked flawlessly
