NEW PRODUCT – Gameduino shield for Arduino. Gameduino is a game adapter for Arduino – or anything else with an SPI interface – built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers. The sound and graphics are definitely old-school, but thanks to the latest FPGA technology, the sprite capabilities are a step above those in machines from the past.

• video output is 400×300 pixels in 512 colors
• all color processed internally at 15-bit precision
• compatible with any standard VGA monitor (800×600 @ 72Hz)
• background graphics
  • 512×512 pixel character background
  • 256 characters, each with independent 4 color palette
  • pixel-smooth X-Y wraparound scroll
• foreground graphics
  • each sprite is 16×16 pixels with per-pixel transparency
  • each sprite can use 256, 16 or 4 colors
  • four-way rotate and flip
  • 96 sprites per scan-line, 1536 texels per line
  • pixel-perfect sprite collision detection
• audio output is a stereo 12-bit frequency synthesizer
• 64 independent voices 10-8000 Hz
• per-voice sine wave or white noise
• sample playback channel



The adapter is controlled via SPI read/write operations, and looks to the CPU like a 32Kbyte RAM.

(Unlike many 8-bit machines, there are no restrictions on when you can access this RAM). There is a handy reference poster showing how the whole system works, and a set of sample programs and library.
