One question has been b= othering me. How do I wait properly in a rtdm driver routine, i.e. I need= to wait a few microseconds for a register to "settle" or for the codecs = to come back from reset. This would be required in both routines that can= be called from realtime as well as non-realtime tasks. That's a typical job for rtdm_task_busy_sleep(): Jan --------------enig09A931CD0EFF41A9974AF030 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFWHtrniDOoMHTA+kRAmhTAJ4mMFAtu7Xc786LZnwlRoimtHr8ggCbBPjL va4MRfjCN4CEjYrCZAQl2g8= =16HQ -----END PGP SIGNATURE----- --------------enig09A931CD0EFF41A9974AF030--
