Can't find LV_TICK_CUSTOM

Hi !

I followed this tutorial https://docs.lvgl.io/8.1/get-started/arduino.html but I just can’t find LV_TICK_CUSTOM in lv_conf.h

I use ESP32 Wrover devkit4 with Arduino core and LVGL 9.1.0 from platformIO.

You are using LVGL v.9.1.0 but the documentation you linked is for version 8.1.
See Arduino — LVGL documentation for updated documentation.

Owww, you are right. Thank you.
