Interesting project, sort of. If it had real testing value, making a PCB for it would seem compelling, in order to help folks reproduce it. On the other hand, don’t most of us have -pa-LENTY- of VGA devices at hand? (Too many pooters in my house, I swear.)

Nobody has heard of it. I was looking for a simple way to do OSDs 2 years ago and asked around all sorts of EE forums- not a single person had a good one-chip solution.

nice point skot. i’ve been using the parallax prop for a while now and have noticed that no one seems to be giving it the recognition it deserves. hopefully someone will start sending in a few projects with it. i would send send in my projects, but most of it is closed source industrial stuff.

It’s not good to do BSF/BCF instructions on IO ports on PICs due to the read-modify-write problem.

Nonetheless, interesting project. I haven’t played with video yet….

Seriously, has nobody heard of the Propeller chip from parallax? they start at like $13 and can do VGA/Composite/etc output like a mofo.

The demo board (More like $100) comes with a VGA connector on it. Start doing realitively high resolution (for a mC) VGA graphics in minutes..

this needs to be in a small vga hoodie. way to big for what it does
