@VigneshAkshaya I have reviewed your project, and I found there're some uncorrect configurations. You can modify them as follow:
- SampleProgramLVGL8.2/components/lvgl/lv_conf.h:
- SampleProgramLVGL8.2/components/lvgl/lv_port/lvgl_port.c:
from esp-dev-kits.
@Lzw655
I have tried with the above configurations and it is working fine for labels, but I dont know why it is not working for other widgets.
• Button was created and added to the existing “Hello World “ text – Only “Button” text label is getting displayed.
• Event was assigned to the button to follow up the button event – It’s not clickable and given event also hasn’t happened.
• And , widgets such as bar , slider , switch were also tested and only text is getting displayed for all .
Changes I have made,
main\hello_world_main.c -> btn1 is created and its corresponding event handler .
Hardware Observation as below
from esp-dev-kits.
@VigneshAkshaya I checked the file "components\lvgl\lv_conf.h" in your project again, and I found the configuration "LV_USE_THEME_DEFAULT" is set to 0 which should be 1. This caused LVGL's widgets to have no default appearance.

@VigneshAkshaya Is your problem solved? If so, please close this issue.

Hey @Lzw655 , sorry for the delay, I was unavailable for whole past 2 weeks.
• “LV_USE_THEME_DEFAULT” was set it to 1.Dsiplay is changed and there was no response on clicking the button
• I2C Bus and LCD Touch Init are also happening properly . Verified through ESP ERROR CHECK and print statements for all the init functions.
• LV_EVENT_CLICKED given to the event handler is not working whereas other default events are happening – verified by printing event codes.

Sorry for not responding to your question in a timely manner!
Since this problem has lost its time, I will close it after a week. If you still need to solve this problem, please leave a comment or open a new issue, thank you!
