We should have "PWM" on there Harald by FIQ, it should be similar functionality as hardware PWM. It should respond to cat /sys/devices/platform/neo1973-vibrator.0/leds/neo1973:vibrator/brightness as usual. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAki3sI4ACgkQOjLpvpq7dMpJzwCdH1LJobwVv6UnjEXw4LmjDfP0 LX4AoIZJXe3MrF9JbBJO8K8oG14TfPid =wVvd -----END PGP SIGNATURE-----
