Well despite it isn't the hardware SPI we actually need, that's good work: well done, that's quite a chunk of the battle. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkisnzkACgkQOjLpvpq7dMrUgACfTdrwXyv7t0x2tx4OohZ8kWqU W5kAnjYz/qDxbB7Mfh7ZJVcKrUjpi8yy =UtbJ -----END PGP SIGNATURE-----
