Hello Everyone! I've created a CPLD-based Arduino-compatable controller that is shield stackable or can function stand-alone. I'm opening it up for beta testing for those who are interested. Please visit my site for more details: http://majolsurf.net/wordpress
The Amani 64:
In short, The Amani 64 is a low-cost entry-level CPLD development kit, stackable with the Arduino, other Amanis, and Arduino-compatible shields. As the project grows, higher-density variants of the board will become available, including FPGAs. Also available for test are application-specific interface modules as well as a low-cost USB-based JTAG programmer. The project potential for this board ist limited to the imagination. While a capable stand-alone controller, the board is "multi-stackable" thus allowing for a data-bus to be created between the Arduino, multiple Amanis, and shields on the PB/PD connectors. Additional I/O is available on the front ports to pass data to external devices. The board is compatable with both 3.3V and 5V devices.
I'm pretty excited about it and think Arduino fans will be too. I'm happy to be in the beta test phase so I can get feedback from folks in the field and free up my time to play with it more. Please contact me here or at the email address posted at my site if you are interested!
