Here some FPGA developer boards http://www.gaisler.com/cms4_5_3/index.php?option=com_content&task=section&id=9&Itemid=29 starts with Spartan3 FPGA for 750 Euro. But i found some postings that the Spartan3 is possible to buy for 10-20 Euro (price for ordering only one) OpenMoko/Neo1973 is already a great step - much cheaper than other embedded linux developer kits - so when it would be a FPGA kit, too :)))) Is it right, that a FPGA is full programmable with a SPI connection? *G* rob _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/cgi-bin/mailman/listinfo/community
