This example provides a description of how to configure DMA2D periph in
Memory_to_Memory with pixel format conversion transfer mode and display the
result on LCD.

the pixel format conversion and the transferred data after pixel format conversion
In this example the pixel format conversion is done from RGB565 to ARGB8888
and you can see on LCD the difference between the two images
