DESCRIPTION:
Your design requires color VGA video, or it might be nice to have, but generating VGA color video is no small task even for
the hardiest of embedded controller or processor. Choosing a specification, generating sync signals, managing the video
memory, and screen refreshing just to name a few are major tasks. Your embedded controller or processor may not have
the horsepower, program memory, or I/O pins to spare for these tasks. Need a module to do all of this for you so you can
concentrate on your design requirements? The ezVGA Serial Module is your solution.

The ezVGA Serial Module is a ready to use embedded color VGA video card that will deliver color VGA video functionality to
your design. The ezVGA Serial Module takes away the problem of needing an enormous amount of I/O pins and lots of
processing power typical for high resolution color VGA video generation and replaces it with only 2 serial communication pins
and simple to learn and use commands. The ezVGA Serial Module offers you a quick and cost-effective way to generate
color VGA text and graphics.

Everything you need to get started quickly is housed on a 2.5" by 3.1" SIP module, even right down to the VGA monitor
connector. Just apply power and go. Commands are sent and status received via a TTL level two-line serial asynchronous
interface. The command set gives you the ability to clear areas of the screen, change the background color, clear the entire
screen, define custom characters, use a floating character which can be used for a point-and-click interface, draw lines,
place characters, and read pixels from and write pixels to the screen. The floating character can be displayed and moved
around anywhere on the screen without disturbing any of the image on the screen. This adds another level of character
display.

The screen resolution is 320 by 240 pixels and there are 64 colors to choose from. The ezVGA Serial Module comes with a
built-in ASCII character set and gives you the ability to define up to 256 characters. You can also change the built-in
character set to fit your needs. The screen is laid-out as a bitmap. This means there are no character cells which gives you
the freedom to place characters wherever you need. This gives the ezVGA Serial Module the flexibility to meet any of your
design needs.

Connect the ezVGA Serial Module to any VGA video device and your ready to effortlessly draw color text and graphics.
