Full screen images and icons
The Discovery uses one flash sector (sector 6) to store all full screen images and
icons. A full screen image is defined inside a pixelarea of 240 x 128 pixels. An
icon is defined inside a pixelarea of 24 x 32 pixels. Just like the font sets, only
bits 0-5 of the flash memory are used for the bitmap contents. This means that a
full screen image uses 5120 (0x1400) bytes of memory. An icon uses 128
(0x80) bytes of memory.
This results in the following memory map (every bitmap is user definable) :
