Josef,
I was completely wrong in what I said about expecting the code to work as described.
I just ran the code, as received from RNT, and it worked exactly as described in the article.
I can only imagine that I was so confused back when I was doing this tutorial, that I didn’t clearly analyze the code to be sure I knew exactly what it was doing.
Back some time ago, I was exploring most of the articles Rui & Sara wrote dealing with several processors. I bought all their books and tried to explore everything, and I probably went too fast!
I’m sorry for misleading you, but I can tell you it is my experience that Rui & Sara are the very best at what they do, and they will give you all the help you need to be successful with their projects.
I’m certainly willing to help you, if I can, and I’m now taking more time to analyze the project code before I try running it.
I can tell you that in my 56 years of programming, I discovered the real learning occurs when you make the code you own (by modifying it to do something slightly different than its original purpose.
Good luck with your projects, I wish you well.

I’m sure I can help you.
I’ll need a day to get my stuff together — it’s been a while since I did anything with this project.

In reply to Ray Leiter. I changed it according to your suggestion and I got a red button and ON instead of a green button and OFF. What else should I do to make the project fully work? Best regards

Hi.
In that case, you may need to uncomment
#define TFT_INVERSION_ON
in User_Setup.h

Let me know if this fixes the issue.

Regards,
Sara

My sketch worked correctly, but I’m having problems with the colors. Instead of red I have magenta. Instead of green, I have Cyan. I tested on two ESP32 LVGL modules with the same problem.

In reply to Mark D. It seems to me that problem is TFT_sPI version. When I downgraded Ver. 2.5.43 to 2.5.34 example sketch "Display Text, Create Buttons and Slider" works ok after RND User_Setup.h update.

In reply to Pentti. In that case you should have used the correct drivers. Have you tried the earlier tutorials for the CYD without LVGL. It is work trying them first

My mistake!
There is only one USB port on board. Boards are bought via Aliexpress:
