Action

Start an animated screensaver.

 

 

Syntax

CmdScreenSaver

 

 

 

Remarks

After the screensaver command, the co-processor engine continuously updates REG_MACRO_0 with VERTEX2F with varying (x,y) coordinates. With an appropriate display list, this causes a bitmap to move around the screen without any MCU work.

Command CMD_STOP stops the update process.

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

 

REG_MACRO_0 is updated with respect to frequency of frames displayed (depending on the display registers configuration).

Typically for 480x272 display the frame rate is around 60 frame per second.
