Write Scan Line and Advance

\i D N A word::no_of_pixels word::p0 ...

Parameter	Type	Range	Description
no_of_pixels	word	1 ... display width	number of pixels to write
p0 ...	color_16bit	0x0000 ... 0xFFFF	color value for pixels

Writes a horizontal scan line consisting of no_of_pixels pixels onto the screen.

• Data for any sent pixel is made up as a 16-Bit Color Value.
• The location where the pixels are written to (where the horizontal line begins) is determined by the current cursor position.
• The column address is incremented after every pixel. If the column address exceeds the right margin during printing, [NACK] is returned and the command processing returns and waits for the next command introducer (\i). Even so, the scan line is drawn correctly until it hits the screen margin.
• After the command the x cursor postition is the same as before and the y cursor position is incremented.

Response:

[ACK]

Example

\iDNA\D7\X0\XFFFF\XF8\XFFFF\XF8\XFFFF\X0

This example will write 7 pixels to the screen, starting from the current cursor position. The first and the last pixel are black, pixels in between are white or red alternatingly.
