Direct Draw Graphic

\i D G F word::frames word::width word::height

Parameter	Type	Range	Description
frames	word	0 ... 65535 (0 = 65535)	number of frames to be processed
width	word	0 ... display width (0 = full width)	horizontal value for the area to be filled
height	word	0 ... display width (0 = full height)	vertical value for the area to be filled

Puts the controller into streaming mode until the specified number of frames has been sent or the timeout (200ms) has been reached. In streaming mode the iLCD controller cannot execute commands. The parameters "Frames", "Width" and "Height" specify how the iLCD controller will interpret the streamed pixel data. This data must be in the 16 bit format.

• If the values for width and/or height exceed the right or bottom margin, the controller corrects the values accordingly without sending an error.
• 16 bit pixel data can be sent directly following the command or after the ACK response is received.
• A 200ms Timeout is activated after Direct Draw Graphic is received. If the Timeout is triggered a NACK is sent by the controller and the controller exits streaming mode.
• 2 ACKs are sent by the controller. One to confirm the validity of the CALCULATED BYTES TO EXPECT and one to confirm that the CALCULATED BYTES TO EXPECT have been successfully processed.
• Excess bytes are ignored.
• During process execution new commands sent over USB/ethernet will be treated as 16 bit pixel data.

Response:

[ACK][ACK]

Example

\iDFG\D200\D640\D480

Prepares the controller to receive a bitstream of 200 frames over USB/ethernet with a resolution of 640*480.

CALCULATED BYTES TO EXPECT: (200*640*480*2) = 122,880,000
