ESP32-S3 LCD 1.47 with JD9853 horizontal issue

[uwekempe]

I got the display running 90 degrees rotated, but the text is mirrored. I tried to play with the MADCTL value at the display_driver_framework.py without any success. Finally I tried any MADCTL values from 0x00 to 0xFF, but I can't get the text the right way.
I also tried any options of set_style_base_dir, but this is without any effect.
This Image is MADCTL value 0x36

Here is my code

label1.set_style_base_dir(lv.BASE_DIR.LTR, 0)

label2 = lv.label(rect2)

Any idea?

you need to adjust the _ORIENTATION table for the display driver. That is where the parameters are stored for the rotation.

Hey, great, it works. Thank you!

Now I got another problem. I would like to use larger fonts, maybe 24 or 28 pixels. Relating to the LVGL documentation, there are built-in fonts from 12 to 48 pixels, but I can't use fonts larger then 16 pixels. Do I do something wrong?

[kdschlosser]

I am working on fixing the issue with the fonts. That actually just came up not a day or two from another user.

[uwekempe]

Thanks for the reply. It's not urgent, take you time.

I found a different solution, now I'm able to draw any font size and also simple images at the display:
After the lgvl setup (SPI.BUS, I2C.BUS), I set up a SoftSPI and with the slightly modified driver "ili943xnew" (e.g. for the cheap yellow display), I'm able to "talk" to the display (without lgvl). The touch function works with lgvl. And there is another advantage: With the small lgvl fonts, the display hangs up after some hours. Now it is running without any crash, with large fonts.
It looks like this (the goal is to control a heated mirror and some other things in my bath room).
