How to clear display in tasmota-32lvgl

[Khurram]

I am trying to output a sensor value using the lvgl library to the dispaly. I cannot figure out how to clear the display before outputting the current value.

Thanks

Not used lvgl on tasmota for a while.  But don't you just re-instantiate the internal object? 

 lv.obj(0)

Please prefer Discord or Github discussion for these topics.

There is no command to clear the display in LVGL. It is system where you declare object displayed. Clearing the screen means removing all objects.

Alternatively you can also put a black rectangle in front of other objects to hide them.

Finally you can have different "screens" and move from one to another - this is what we do in HASPmota.

Generally speaking, using HASPmota is far easier than native LVGL:

I did not know about HASPmota. I will take a look. Thanks.

HASPmota seems much easier to use that lvgl. The HASPmota link posted above along with this discussion has really helped me.

Thanks
