I am now experimenting with a prototype board that will support mnib and be a lot cheaper. woahah, hey, Nate, you already gave us some hints then and there, but this sounds very promising. Well, Spiro always wanted to add an 8K RAM with SPI interface. Although I found such a chip recently, it is not generally available. With only adding such a chip to the programming interface (MOSI, MISO and SCK), extending the existing xu1541 would be super easy. I, on the other hand, prefer the "integrated way", selecting a microcontroller that is fast enough to do the parallel burst protocol without buffering. The relatively new Atmel AT90USBxxxx chips would be fast enough and more or less compatible to existing firmware source. With Atmel's USBKey there is a cheap development board available... There are more solutions thinkable and I'm curious what your's is looking like. Don't you want to post some pictures? |
