Is there a VGA driver object that I can use with the proto board?

Electronegativity

Greetings Earth Beings!

I am about to add a VGA connector to a Propeller Protoboard and was wondering if there is a Freeware driver available. Searching the Object Exchange turned up a lot of confusing hits.

Also, what resistors do I have to solder to the proto board.

I am not using the kit from Parallax because I don't need a mouse or keyboard and already have a connector that I salvaged from an old computer.

For some basic VGA output, look at:

Look at the schematic on this for resistors:

You should only need to add a few 470ohm resistors. The following document shows the schematic for the protoboards and also explains where the resistors are installed. The 100ohm resistors are for the PS/2 mouse and keyboard so you don't need them if you aren't using those.

Just about any of the VGA drivers in the OBEX or VGA demos should run fine. Just make sure you verify what clock source you are using and also the pins used for the VGA display. A good reference to show the different pins used on the different boards can be found here:

Thanks for the help, I will follow those leads.
