I'm sorry this is not a Microchip Pic but you can use FPGAs to create video signals to generate a video signal:

You can use FPGAs with Microchip Pics if you want and combine the two.

See my other post on "VHDL Tutorial from University of Pennsylvania" for extra help learning VDHL.

Must have missed this post!

You have got me quite interested in FPGA's and have now being toing a bit of reading up on them. I like what this guy has done especially - he created a custom driver for this led display using an FPGA:

I know how easy it is for me to get side tracked when I see a project because I always see another one and another one. I remember seeing something but I don't remember seeing that project. I don't know if people will be interested in different things so I try not to take them to the next level. So I'm sorry if I missed that project.

On another note about LEDS; I was at the Wells Fargo Center because I had free tickets and they had an LED sign that wraps around the whole inside of the stadium which covers the stands and the basketball court. I couldn't comprehend what it took to make it work. It must have been a lot of work.

I think alot of us are like that - being in the middle of one project and thinking of another cool project and then another...

I am in that place right now, I have been working on a project with Stacy, plus I have had the coffee table and super pixel bros and I have been thinking of a new pov project and an updated RGB Coffee table - SOO MANY PROJECTS!

We just got back from vacation and leaving the airport was a huge RGB LED display, I don't think I could solder all those LED's to the board in under a year.

I also wonder about what happens if an LED goes short, because that has happened to me on my matrix's and it turns on an entire column. You then need to replace the shorted LED with a new one.

It might be possible to program an FPGA to emulate a PIC 16f648a and there may be room on the FPGA for other emulation and code. I've searched a little but haven't found anything. It would let you keep doing what you're doing but on a different platform. It is only an idea to expand on the PIC16f648a that I'm not capable of doing yet.

People have emulated entire computers on an FPGA (like the commodore amiga) Now that would take some skill

Simple VGA interface for tiny FPGA boards

He prototyped a 512-color VGA interface board which worked just fine

As you can see on his site, the adapter works quite well, allowing the FPGA to put out a crisp 800×600 image with little fuss. [devb] has also posted all of his design files on his site in Eagle format for anyone interested in replicating his work.

This sounds like a plan! 512 colors and 800x600 is something I'm seriously considering studying. This looks like the same manufacturer of the FPGA in the Gameduino.

The good thing with VGA is that you have separate RGB outputs. Whereas with composite you need to have some fancy coding or converter circuitry to get it to actually display color.

Keep us updated on your progress Chuck!

I managed to get the files for the VGA to breadboard connector. Either the files are attached or I have to load them into Eagle and generate the Gerber files which I haven't done before.
On another note, my Gameduino came today. I have to work on finishing the joystick and pcb that it sits on in order for me to really use it.

This part is on clearance at Jameco. It is part # 1952273. It is the one in the project for the board.
