Action

Take a snapshot of the current screen.

 

 

Syntax

CmdSnapShot  ptr 

 

 

Remarks

 

This command causes the co-processor engine to take a snapshot of the current screen, and write the result into RAM_G as a ARGB4 bitmap.The size of the bitmap is the size of the screen, given by the REG_HSIZE and REG_VSIZE registers.

 

During the snapshot process, the display should be disabled by setting REG_PCLK to 0 to avoid display glitch.

Because co-processor engine needs to write the result into the destination address, the destination address must be never used or referenced by graphics engine.
