Oled font size 128*64

Good day,
when setting the font size to Oled 128*64, I need to enlarge the font but the last two items from the menu do not work.
Is there any way to make the font even bigger?

Thank you

Which exact build did you use (lower left corner of web interface, or sysinfo page)
Some builds do not have all fonts included due to size issues.

The ESP8266 Climate build has the 'LIMIT_BUILD_SIZE' compile-time flag set, with the net result of excluding the rather large larger fonts from this plugin :?

There are 2 feasible solutions:
- Create a Custom build (instructions in this Documentation page)
- Use an ESP32 (read here why), and preferably one that has 16MB Flash, so a MAX build, including all plugins and all features enabled, can be used

Hello,
I have a similar problem.
I use a 128x64 1,3" OLED Display with en ESP32 C3 super mini Build: ESP_Easy_mega_20240414_normal_ESP32c3_4M316k_CDC Apr 14 2024
With 8 rows the signs are too small.
There is no other font than optimized and normal ?

I want to have 4 rows which changes like

Room 1
Temp:
Humditiy:
Pressure:

Wait two seconds:

Room 2
Temp:
Humditiy:
Pressure:

Is it possible? Which build do I need ? I use two BMx80 sensors.

Thank you!
Regards
Thomas

This is what I have at the moment:

You should have a look at P036 OLed Framed plugin, enable both Hide header and Hide indicator, set the Lines per frame to 4, the scrolling to Instant, and the Interval to 2.

That's strange, as it is using the same library... :shock: (AFAIK)

Nope it is not the same....
Please check to see if you actuall have a SSD1306.
And you could also try to set different brightness levels as some SSD1306 do not allow all brightness levels and the display may start making strange noises when you set it to a non-supported brightness level.
Maybe this typical 'coil whine' can also corrupt stuff in the display?

Mr. Ali tells me that my displays have SH1106 chips, so maybe this is the problem?
How can I find out which chip is on the display?
On the display itself I cannot find an information about the chip

How can I change the brightness ? I found nothing in the esp easy config ? I can change the contrast ?

Finding that kind of data/info is always hard, especially if the chip is hidden...
You can easily switch the display type in the settings.

Yes, Contrast is the term used in the settings
