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…
It’s almost as easy as…
mySerial.begin(9600); // Set baud rate for serialVGA board
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??
