Technical Overview
The demo simply uses the VGA API to print “Hello World” on the screen. When the printing reaches the bottom of the
screen the terminal scrolls the screen image up one line. The program is so short, let’s take a quick peek at only the
contents of the main() or loop() in the Arduino version:
