Description
trying to run bare project with one obj in esp32 but screen does not open, the setup in pinmode is the same probably display and buffer setup are not the same. Demo is what is is as lv_port_32 and my project uses in half the two templates inside the lvgl/examples/porting
The timer is copied by the demo project.
What MCU/Processor/Board and compiler are you using?
esp32, esp-idf5.0.1
What LVGL version are you using?
8.3/release

Screenshot and/or video
what you see on monitro are differences on buffer size etc. here are the printscreens
