TFT 2.25" issue

Postby mazur888 » Sat Jun 07, 2025 10:46 pm

Hi, I bought couple 2.25" tft's to play with. Had some trouble to get it working with esp32, turns out chip is not st7899, but it is st7899P3.
Got it sorted based on this websites examples:

Everything is ok now apart screen rotation. Whatever I do screen stays the same in vertical position. tft.SetRotation(0) , changing number from 0-3 does nothing but messing screen up. In attachment I have picture of rotation 0 and rotation 1.
Playing with library does nothing as well. Does anybody have any experience with them?
