connected to the LCDDA. The dual-port RAM also needs to have dummy data areas for edge
processing.
using the edge data automatic addition function.
Note: The maximum number of pixels per line is 510 pixels for both 16-bit color and 24-bit color displays.
The following shows examples of how to set original image data to the dual-port RAM
Let us set original image data for 24-bit and 16-bit color displays with 510 pixels per line by
First line (dummy data area)
(0xF800_4000∼0xF800_47FF)
First pixel (dummy data area)
(0xF800_4800)
•
•
To scale up or down an image larger than 510 pixels, it is necessary to divide the image.
Original data: 510 pixels, 24-bit color
Original data: 510 pixels, 16-bit color
The first line is handled as a dummy data area. It is therefore not necessary to set
image data at addresses 0xF800_4000 through 0xF800_47FF.
The first and last pixels in the second and subsequent lines are also handled as a
dummy data area.
