It might be better to extend [comport] to handle SPI devices.
Assuming you have a /dev/spidev* already existing (I just spent a couple
of days getting that far on a Beaglebone Black), the rest of it is quite
similar to ordinary asynchronous serial communications.

working on a project to that will use Pd running on a Raspberry Pi, and

I know about Miller's gpio external, found here:
http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm , but it does not do
any of the SPI interfacing, which is the way that will need to interface
with the DACs.
Is there any possibility (Miller or anyone smarter than I am on this
stuff) to extend the gpio external to include SPI interfacing?
Thanks in advance,
Dan
