We once asked Samuel about SPI, and he said that it would be slower, but still good enough. (In real life, the theoretically possible maximum speed is rarely reached anyway.) Without digging through the Atheros driver, I don't know how much work it would be to put it on SPI. If the abstraction is clean, it could be very simple. If not, a pain. So if it's not too horrible, I'd prefer the SPI solution. Always better to make it a software problem than a hardware problem :-) - Werner _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
