    Looks very neat :) Just to let you know I also wrote a 2D/3D graphics lib (TGX). The 3D API provides similar features to your library except that it does not (yet) provide sub-mesh culling and is screen/hardware...

    I'm happy I could help :) Beware that the framerate shown is a bit misleading. The max refresh rate for the ILI9341 screen is around 130Hz/140Hz so getting a higher FPS will not improve smoothness anyway. Also, the...

    The 65FPS you obtain is related to the framerate set within lvgl: disp->refr_timer->period = 15; // line 158 of lvgl_music_demo.ino This line tells lvgl refreshes/redraw the UI every 15ms so that the maximum...

    Hi, The TGX library has native support for ILI9341_t3 and Adafruit GFX font format (GFXFont). However, the default 'classic' 6x8 Adafruit font given in glcdfont.h is strangely not in Adafruit GFXFont format for some...

    Hi, This is a silly question but do you have a touchscreen on the ILI9341 and is it wired to the same SPI bus ? I say that because I got caught a few time forgetting the touchscreen was wired and not setting...

    I understand that and my previous answer was only a suggestion and not meant to be rude :) As I understand it, you manage to run the LVGL music demo on Teensy 4 with an ILI9341 screen. Your next question now concerns...
