The difference between the min and mix drive strengths is quantified in the Glamo datasheet, it's like 4mA drive capability -> 1mA drive capability. We did set it to 0 in the end by default and it did not seem to make any trouble. Glad you're working OK! - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiQkcwACgkQOjLpvpq7dMquOgCgj5nf2sVHJ/3uBEDOR17qcYaY ATsAnjccRN7pXpEk65SV5Th+/UnZWpoC =48O1 -----END PGP SIGNATURE-----
