In reading this, remember that anything I don't complain about looked
fine to me. Overall this looks like pretty good code (though I haven't
compiled it and of course have no hardware to test it on). Thanks for
your continuing efforts on this SPI stuff.
[-- Attachment #2:
I've been mulling over how to use later Fanuc brushless motors that have
the serial encoder.
I have gotten just a little bit of data about them. Apparently, they
send a 77-bit string at 100K bits/second.
So, the readout takes almost a ms. Now, a lot of people would want to
convert this to

One problem shows up immediately, they have 65K and 1 million count/rev
versions.

Yes, bursting counts would ruin the timestamp
It would be convenient if you could teach your mailer to attach these as
text/plain or text/x-patch.

but the hal function mesa_7i65 does both reading and writing in one go.
I did originally start with two functions and then combined them.
However, I think there is

Yes, you must send to receive with SPI so unless you want to duplicate the
sending (Looking at the 7I43 timing I would think not) you need to reverse the
normal order of read write (for SPI only). This means that the read data is

I have been following this thread with great interest. I presume
the 7i49 (six-input resolver) is similarly affected due to its
use of SPI to the mothercard? Is this so? I have a 7i49 here
if it will help in any way (indirectly) with the 7i65.
Also, note that doubling the speed of the servo

Well, the trouble on my end is not *too* bad, just a few extra
keypresses.
