Apologies if I have missed previous discussions, but searching on the product name... SerialToVGA... turned up nothing.

How about a little board costing about $36 incl p&p which, with commands over a TTL serial signal, will drive an ordinary VGA monitor for you? 50 lines of 100 characters, in "simple" mode. You can also have windows. Automatic line-wrapping and scrolling. And colors. There's a "goto position x/y" command.

Comes from Hobbyelectronics.co.uk (With whom I have no connection, beyond "happy customer")

Does anyone know of a US source?

For the really, really basic "getting started" stuff, see...

http://www.arunet.co.uk/tkboyd/ec/SerialToVGA.htm

It's almost as easy as....

void setup()
{
  mySerial.begin(9600); // Set baud rate for serialVGA board
}

void loop()
{
    mySerial.print("Hello world. ");
    delay(150);//Just to make it easy to se what is happening.
}

One pin "used up" to drive the VGA display. No processor overheads.

Has anyone using one found any downside??
