The small (83mm x 53mm x 20mm) Arduino-compatible shield features the Bridgetek EVE graphics controller operating at speeds of up to 1.1Gps. The controller offers 32-bit internal colour precision for graphics processing and can support up to 2000 sprites.
The EVE IC is supported by a Xilinx Spartan-6 FPGA that has 8MByte embedded flash, a 24-bit HDMI video interface, as well as JTAG, SPI and UART I/Os. MicroSD memory card support and a pair of Wii Classic controller ports are also available.
The BT815 allows the new Gameduino to provide 1280 x 720 pixel HD graphical content and 48KHz stereo audio to a large format display or TV screen. HD video playback can be accomplished at 30fps frame rates.
Gameduino has been designed to support the development of immersive games, as well as other types of multimedia projects, through the C+ programming language. The CircuitPython open source programming language can also be used to program the board. The Gameduino 3X Dazzler has the power to run 2D gaming projects and sophisticated 3D renderings. A wide range of project examples and demos are available online to allow development to get started quickly. The new Gameduino will also be available as a streamlined core module This still has the graphic controller, programmable logic and HDMI capabilities, but allows easy integration into existing hardware.
The Gameduino 3X Dazzler is currently being crowdfunded and is close to reaching its target. The link to contribute is below.
The Bridgetek BT 815 provides:
