Issue with RA8876 Display

[helmar74]

I have a ESP32 connected to a RA8876 Display. I have 2 of such devices. Both were working well so far.
But today one of the devices is "only" black, the other one is working
When I open the console of the broken devices I see this in weblog:

I frequently see "HTTP ERROR", which isn't shown on the working device.
So I'm not sure what is causing the error. I replaced the ESP32 to a new one, which doesn'T fix the issue.

Wiring diagramm:

Anyone an idea, what I could try to fix?

[sfromis]

Those "HTTP ERROR" is due to trying to display an image served from another server via the specified URL, and failing. It will treat the image reference as an URL, prefacing it with http:// if it could not find your image, which seems the be the basic issue there.

However, this may not be the only issue, and when you have one device working, and another not, the question becomes what there may be of differences in configuration, commands, wiring or power.

Hi thanks for the hint ;-)
The files are stored on a local SD Card in the Display.
First I put the old SD Card in a card reader on my PC and the files showed up.
To be sure I replaced the SD Card.

At the moment it is working again... and the HTTP error is gone for now.

Will have a look on it.

Thank you very much.

I'll report back in a few days if it is fixed for sure

[helmar74]

It looks like the SD Card is broken.
btw a other question:
How can I show a picture, which is hosted on a Webserver?
I tried the following commands:

Displaytext [x312y70P/http://192.168.1.50:8080/static/infodisplay/anruf/buerogr.jpg:]
Displaytext [x312y70P/"http://192.168.1.50:8080/static/infodisplay/anruf/buerogr.jpg":]
Displaytext [x312y70P/'http://192.168.1.50:8080/static/infodisplay/anruf/buerogr.jpg':]

but none of them is working. (The link is correct and working in browser)

[sfromis]

You should not duplicate what it is already doing. As I wrote, the code is

prefacing it with http://

To be clear, I've not tested it, just observed what the code seems to be doing.

[helmar74]

OK I tried the following (without http:// in front):

Displaytext [x312y70P/192.168.1.50:8080/static/infodisplay/anruf/buerogr.jpg:]

Output is:

13:43:28.878 CMD: Displaytext [x312y70P/192.168.1.50:8080/static/infodisplay/anruf/buerogr.jpg:]
13:43:28.882 MQT: stat/esp32_1/RESULT = {"DisplayText":"[x312y70P/192.168.1.50"}

It seems that the port (with delimter : ) is causing the issue

UPDATE:
I also tried:

14:05:04.442 CMD: Displaytext [x312y70P192.168.1.51/buerogr.jpg:]

which ends up in:

14:05:04.576 MQT: DVES_PASS/RESULT = {"DisplayText":"[x312y70P192.168.1.51/buerogr.jpg"}

But picture isn't shown,( URL is working in browser and picture is working if loaded from sdcard)
