can someone explain to me what is wrong here?
The graphics memory is not deleted.
Here I begin:
then I go here
actually there should be a sun, but it will be green
there is a sun
here is the same sun to see, but will not be here at any time
perhaps upload hmi to find error in code
Definitely, a green SD card does not show if not called.
Nextion uses simplex statement.
To use complex statements,
the full evaluation will happen on each val after operator - in full.
Change of page will indeed change graphics
All is dumped to loaded from HMI as per design
Only a no-background page will keep old
- with such page selectively overwriting existing
