9 sensors, LCD, flash, toggle stick, and more.  You can use AVR-GCC to
20 SPI protocol drivers interact with the AVR, and could even let the AVR
22 easily with a "real SPI controller", instead of this bitbanger.
25 The first cable connections will hook Linux up to one SPI bus, with the
28 connector pins (used also on non-Butterfly AVR boards).  On the parport

44 by clearing PORTB.[0-3]); (b) configure the mtd_dataflash driver; and

55 Or you could flash firmware making the AVR into an SPI slave (keeping the

59 The "USI" controller, using J405, can also be used for a second SPI bus.
60 That would let you talk to the AVR using custom SPI-with-USI firmware,
