Hey everyone,

I've been hacking some more with my Netduino and have had some success with connecting to the Gameduino 2. I'm not done porting yet, but I thought it might be useful and someone might have some fun with the examples I have completed. Right now I have most of the basic examples up and running, including Hello World (text), Blobs (touch screen and shapes) and Simon (sound and touch targets).

I've attached two very unfortunate pictures below, but they sort of get the idea across.

In case you were wondering if it was possible, or even practical, the answer is yes! Some special considerations have to be made for speed, but the Netduino does a pretty good job. I'll be finishing up porting the library and all of the examples over the next week or so.

As a sneak peak, here's how simple it is to get started with the Gameduino 2 and your Netduino!

        public static void Main()
        {
            GD2.Init();

            GD2.ClearColorRGB(0x103000);
            GD2.Clear();
            GD2.DisplayText(240, 136, 31, GD2.Options.Center, "Hello, Netduino!");
            GD2.Swap();
        }

Cheers,

Giawa

Looks cool! Is that a touch screen to play the game?

Yes, it's a resistive TFT touch screen and the 'GPU' is the FT800. You can read more about the tech specs, etc here: http://excamera.com/sphinx/gameduino2/

Gameduino 2 is a shield that adds a bright 4.3 inch touchscreen, an embedded GPU, headphone jack, accelerometer and microSD slot to your Arduino - or anything else with an SPI interface. Everything you need to create compelling games � right in your hand.

video output is 480x272 pixels in 24-bit color

OpenGL-style command set

Up to 2000 sprites, any size

256 Kbytes of video RAM

smooth sprite rotate and zoom with bilinear filtering

smooth circle and line drawing in hardware - 16x antialiased

JPEG loading in hardware

built-in rendering of gradients, text, dials and buttons

Cheers,

Giawa

Were you able to display images?

I stopped my porting because of that...

Biggest fault of Netduino? It runs by electricity.

Yes! I'm just working on that this weekend and here is a screenshot (again, with my unfortunate phone camera).

This is a bitmap image being loaded into memory and then text being laid on top. I don't have a micro SD card around (just ordered one off Amazon), so I wrote a quick program on my computer that converts the images to a byte array to store in the actual Netduino program. I'm holding off on committing that code to GitHub until I can actually do file loading. However, I don't expect any major stumbling blocks.

            GD2.Init();
            GD2.Load(mono); // this is a byte array for now - make it a file when I have a micro SD

            // clear the screen
            GD2.ClearColorRGB(0x375e03);
            GD2.Clear();

            // draw the bitmap itself
            GD2.Begin(GD2.Primitive.Bitmaps);
            GD2.ColorRGB(0x68b203);
            GD2.BitmapSize(GD2.Filter.Nearest, GD2.Wrap.Repeat, GD2.Wrap.Repeat, 480, 272);
            GD2.Vertex2ii(0, 0);

            // now draw some text
            GD2.ColorRGB(0xffffff);
            GD2.DisplayText(240, 136, 31, GD2.Options.Center, "Images?  Check!");

            GD2.Swap();

Cheers,

Edit: Just got game Gameduino logo demo going. Attached screenshot above.

Edit 2: Just added JPEG decoding. Got stuck on something *really silly* for a while >.<
