Display SSD1306 not Working after Upgrade to Tasmota 14.0.0 an Universal Driver

[helmar74]

PROBLEM DESCRIPTION

After Updating my ESP8266 with Display SSD1306 to Tasmota 14.0.0 the display isn't working anymore.
I compiled myself, as I also want to use SR04 Sensor and display the measured value on the display.
Here's my user_conf_override.h

I created a Script on the Device which looks like this:

>D
:H,SSD1306,128,64,1,I2C,3c,*,*,*
:S,0,2,1,0,30,20
:I
AE

A4
A6
AF
:o,AE
:O,AF
:A,00,10,40,00,00
:i,A6,A7
>B
->displayreinit
#

I also configured a GPIO with "A" Option

After that the display is dark
I tried script> dt[] commands in console, but nothing shows up

What I'm doing wrong?

Thanks for you help in advance

[sfromis]

The docs says that you can have the display.ini content in a special >d section in the script, which is different from what you used, >D.

[helmar74]

so i have to use "lower case" <d ?

[sfromis]

Yes, lower case >d is what the docs says.

[helmar74]

OK, I changed the script to:

>D
>d
:H,SSD1306,128,64,1,I2C,3c,*,*,*
:S,0,2,1,0,30,20

but it still not wokring...

[helmar74]

Config of Device:

[sfromis]

Better follow the docs...

Set an unused GPIO to Option A3

That's the dropdown to the right, for the 3.

[helmar74]

ok got it running now. Sorry for being so stupid ;-)
just another question.
I used Displaytext commands with the old driver. is this still possible with universal display driver?
My display is showing the values, but not in a nice way...
Is there any documentation regarding displaying text on the display?

[sfromis]

Not used that combo, but as a starting point I'd expect DisplayText to still work, with the usual docs for that.... https://tasmota.github.io/docs/Displays/#displaytext

[helmar74]

unfourtnately not.
I tried DisplayText [x50y50r200:100] but nothing happens on the display.
Some further informations:

21:57:59.372 CMD: displaymode
21:57:59.378 MQT: stat/sonoffWemosMini_6/RESULT = {"DisplayMode":0}
21:58:03.378 CMD: displaymodel
21:58:03.383 MQT: stat/sonoffWemosMini_6/RESULT = {"DisplayModel":17}

Do you have a example, how i can clear the display, draw a rectangle and show some text?

[helmar74]

And the docs for universal display driver shows a 404:

[sfromis]

Docs (which I already linked to): https://tasmota.github.io/docs/Universal-Display-Driver/
However, that's not where you find DisplayText.

When it comes to that, I'd suggest you to post the full set of commands which you already had working, but which fails now.

[helmar74]

OK, this command worked before and now shows rubbish on the display:

displaytext [z]
DisplayText [x0y0r128:64]
DisplayText [x10y2s2f1]Salzstand
displaytext [x30y19s2]53cm
displaytext [x30y37s2]56%
displaytext [x5y54s1]14.05.2024 22:23

The text is shown "overlapping" on the display

[sfromis]

When using those commands on ESP8266 Tasmota 14.0 with SSD1306 + universal display, what I get does not look too bad.

The yellow at the top is due to my SSD1306 having a band of yellow pixels, still monochrome.

[helmar74]

ok, good to hear. did you compile with the same options as I did?

[helmar74]

displaytext [z]
DisplayText [x0y0r128:64]
DisplayText [x10y2s2f1]Salzstand
displaytext [x30y19s2]53cm
displaytext [x30y37s2]56%
displaytext [x5y54s1]14.05.2024 22:23

did you also configure the display with script... or did you do it with rule 3?
Could you please send me the script or rule you used, please?

[helmar74]

I build up a testdevice with the display and my compiled version with the user_conf settings above. The display is recognized by esp8266 but is dark and I can't send any text to it. I used the script above for configuration and made the same settings.. here some output of the device:

Has anyone an idea, how I get this display to work or what I can try?

[Jason2866]

@helmar74 For the future, please only open an issue if you are quiet sure it is a bug in Tasmota.
For everything else open a discussion. Thank you.

[helmar74]

Will do so, thanks for the hint ;-)

[helmar74]

Manage to get it work. I reflashed my ESP (erased it completly) and set it up from scratch. Now the display is working

Thank you for you great support!
Is possible to donate somewhere? (e.g buymeacoffe or so)

[sfromis]

Good that you got it to work. Still does not explain what happened....

My testing setup was not using scripter nor rules to store the display descriptor, but simplified using a general-purpose setup with a file system (#define USE_UFILESYS, GUI_EDIT_FILE and GUI_TRASH_FILE), to house display.ini (and a test.bat file with the commands for UfsRun).

If you want to donate, there's a button for that on the front page of both the project and the docs.

[helmar74]

Donation done ;-)

[speccy88]

I have an esp8266 with an SSD1306. The display was working fine in 13.4 but stopped working at 14.0
I tried to follow the doc for universal display driver but I fail. Is there a way to make it work with the plain Tasmota Display binary without having to recompile anything? The only way I thought it could work was with rule 3, I tried various way to input the ssd1306 descriptor but can't figure out how to do it correctly.

Anybody can give me an hint?

[sfromis]

You need no recompile for using uDisplay.

Here's the display descriptor formatted as one line, which I've successfully used with ESP8266+SSD1306, and precompiled tasmota-display:

Rule3 :H,SSD1306,128,64,1,I2C,3c,,,* :S,0,2,1,0,30,20 :I AE D5,80 A8,3F D3,00 40 8D,14 20,00 A1 C8 DA,12 81,9F D9,F1 DB,40 A4 A6 AF :o,AE :O,AF :A,00,10,40,00,00 :i,A6,A7 #

Do not enable the rule set.

You also need to configure some unused pin with Option A 3.

[speccy88]

Thanks, that worked
