Hello,
How it possible to change pictures of power level of the accum (for example) on the top of
display, one picture to one level (0-25%, 25-50%, 50-75% and 75-100%).

There are 2state buttons (val=0,1), but I need more states.

Thank you.

Hi
It can be achieved in several ways.
I’m using a picture in my projects. On which several sprites are drawn that display the battery status. Using the timer and xpic function, I display a sprite that corresponds to the battery charge value. Litte magic with math and index can be done in one line.
