Color display not working

Not entirely sure, but I don’t think so.

ok, 4.2 did install.

Back to the repeating Motion chip ... Motion chip timeout, trying auto-reboot of motion chip!

displaystate

show /tng/280x240/biocircuitry.pqf

returns

Showing /tng/280x240/biocircuitry.pqf

It does try to show something, but the screen is all garbled and the motion chip error stops. Looks like it crashed.

I have USB type set to Serial + Mass storage + WebUSB. The file biocircuitry.pqf is 5290kb.

Can you send me the file?
I’ll give it a try.

orntar · December 31, 2024, 5:16am

I pm’d you a link.

I was finally able to update the proffie arduino plugin(4.6), in order to eliminate that variable. I am still having some issues, although the motion chip error seems to be gone.

I tried displaystate and got:

to_send: 0

PCLK1: 40000000 PCLK2: 40000000

frame = 0 rownum_ = 0 next state: 502 buffered rows: 1

I tried show /tng/280x240/biocircuitry.pqf, and got a garbled screen, but it seems to be animated.

So, it seems to be workingish, but doesn’t show an animation upon boot up, or at all, unless its called. Then the animation is scrambled.

Could it be resolution? I ran dpqoi on it and the images are 280x205. the display is technically listed as 240x280, could it be trying to display sideways and not fitting?

profezzorn · January 10, 2025, 3:01am

pqoi should be able to display images/video which is smaller than the screen, but it is not able to handle images which are larger than the screen. Rotating the screen is possible, but has to be done at the startup stage, and a 280x205 screen is different from a 205x280 screen.

So yes, it could totally be doing things sideways and not fitting. (It really ought to spit out an error if you try to use a video or image that is too big, I’m going to check/fix that.)

As for not showing the boot screen, what does the “effects” command say?

Finally: It sounds like this is working better with 4.6 than with 3.6, is that correct?

Looks like it already prints out an error if the file is too tall or too wide:

Not sure I ever tried 3.6. I could if you need more info. but 4.6 is giving better results than 4.2.

Did you get a chance to look at the files? Likely the pqf is the wrong resolution.

orntar · January 10, 2025, 3:16am

I will go look, maybe I missed it. I am doing the pqf on a linux laptop. everything else on a windows desktop.

profezzorn · January 10, 2025, 3:18am

It could also be that I have messed up something related to this display.
I’ve been meaning to try it myself for a while, it’s probably time…

It’s not showing your boot.scr file.
Where did you put it?

orntar · January 10, 2025, 3:27am

it is in the folder \tng\280x240\280x240_boot.scr

I remade the pqf with a smaller resolution. It is now 240x176. I didn’t see any errors (but is smaller).

When I type show /tng/280x240/biocircuitry.pqf I still get a garbled screen, but it appears to be animated.

profezzorn · January 10, 2025, 4:53am

I think it should be \tng\280x2480\boot.scr

(If there is an instruction somewhere I need to update, please let me know.)

orntar · January 10, 2025, 5:24am

ok, I tried that, no difference. Nothing shown on boot, show ... just shows a garble image.

instructions look ok, not sure where I got the file name.

profezzorn · January 10, 2025, 5:27am

Did it show up in effects ?

orntar · January 10, 2025, 5:31am

Yes, looks like it found the files. Nothing on the display.

profezzorn · January 10, 2025, 5:33am

Well, it’s a step in the right direction at least.

profezzorn · January 10, 2025, 9:26am

If it’s any consolation, I get garble too.
Hopefully I’ll have a solution soon.

profezzorn · January 10, 2025, 10:08am

Try it now. (with the latest changes from github)

orntar · January 10, 2025, 1:26pm

It worked!

orntar · January 10, 2025, 1:43pm

I think I found where I got the names…
