Display Memory Update
This function copies the contents of a 512-byte buffer from PIC32 memory to the display. The display memory is
organized as four pages of 128 bytes each. Each memory page corresponds to an 8-pixel-high stripe across the
display. Each byte in the memory page corresponds to an 8-pixel-high column on the display. The least significant
bit in a display byte is the top most pixel, and the most significant bit the bottom most pixel. The first byte in the
page corresponds to the left most pixels on the display and the last byte the right most pixels.
This function assumes that the display buffer to be copied is the global variable
