my lvgl screen is not applied to whole display and my hello world example is diplayed in a slanted form i am not getting straight one i gave hor : 160 and ver : 128 orientation : landscape dpi :15
i am using esp32 wrover IE module custom board “esp-idf” FRAME WORK
i want to get basic widgets on my display like button, tabview ,image and prper labels
i have cloned lvgl_port_esp32 project from git and made chnages as suggested in components in lvgl configuration and lvgl tft display configuration mine is a non touch display
Code to reproduce
i did not change the code it is an eample code given by lvlgl
The code block(s) should be between ```c
and ```
