Hi There,
Here is the output below I am getting when I run the code for learn LVGL 1.8 testing the touchscreen.
I have a CYD with 1 USB C connector, could I please have a little help with this, I have tried the TFT inversion via setup.h and also the suggested code. WiFi scan does work.

Hi.
What happens exactly after uploading the code?
Do you have any more information in the Serial Monitor?
Regards,
Sara

Hi Sara,
Thank you for your reply,
After clicking upload I get the two lines in red:
C:/Users/danw1/AppData/Local/Arduino15/packages/esp32/tools/esp-x32/2411/bin/../lib/gcc/xtensa-esp-elf/14.2.0/../../../../xtensa-esp-elf/bin/ld.exe: warning: C:/Users/danw1/AppData/Local/Arduino15/packages/esp32/tools/esp-x32/2411/bin/../lib/gcc/xtensa-esp-elf/14.2.0/esp32/no-rtti/crtn.o: missing .note.GNU-stack section implies executable stack

Then after a couple of minutes the code uploads like normal but all I get is the multicolour led lighting up red and nothing happening on the tft display at all.
In the serial monitor I did notice text scrolling through

Hi.
What text is scrolling in the serial Monitor?
What does it say?
Regards.
Sara

Ok actually, I had some progress, the display is not lit up but I can just see Hello World!
In tried uncommenting both invert screen options in the tft library but ot did not work.
I think maybe it is a backlight issue ?

Hi.
What you get in the serial monitor is normal.
I’ll send you an email asking you for more information.
Regards,
Sara
