Programming Examples
The MAX4455 EV kit provides a high-level user inter-
face with free-hand drawing, bit-mapped graphics, and
text-insertion tools. Listings 1 through 5 show some
pseudocode examples based on the MAX4455 EV kit
source code for low-level register access, line drawing,
RGB-to-gray-scale conversion, and block memory
transfer to the OSD.
