Would there be a way to use the slider to control the movement of a linier actuator via a L298N Motor Driver .i.e move the actuator in and out via the slider control ?
Regards,
Brendan

Thanks for publishing this!
I used it to get an old LilyGO-T-HMI-S3 working with LVGL v9.2.2
Also got the “error: ‘lv_log_register_print_cb’ was not declared in this scope.”
I just commented it out and used Serial.printf directly instead.
How does it all work without an lv_ “DisplayFlush”?
Does “#define LV_USE_TFT_ESPI 1” add some magic?
Thanks again.

Hi.
You probably have a different board from the one we’re using.

You may also need to adjust the rotation for your specific board.

Sara

I tried the code and it works correctly but the colors come out different. using the #define ILI9341_DRIVER the colors come out fine but the interface goes crazy and messes things up. any idea what it could be?

Hi.
Thank you for your suggestion, but at the moment, we don’t plan to cover EEZ studio.
