The spinner is an animated overlay that shows the user that some task is continuing. To trigger  the  spinner,  create  a  display  list  and then use CMD_SPINNER. The co-processor engine overlays the spinner on the current display list, swaps the  display list to make it

visible, then continuously animates until it receives CMD_STOP. REG_MACRO_0 and REG_MACRO_1  registers are utilized to perform the  animation kind of effect. The frequency of points movement is with respect to the display frame rate configured.

 

Typically for 480x272 display panels the display rate is ~60fps.

 

For style 0 and 60fps the point repeats the sequence within 2 seconds.

For style 1 and 60fps the point repeats the  sequence within 1.25 seconds.

For style 2 and 60fps the clock hand repeats the sequence within 2 seconds.

For style 3 and 60fps the moving dots repeat the sequence within 1 second.

 

Note that only one of [[CmdSketch]], [[CmdScreenSaver]] or CmdSpinner can be active at one time.
