I'm working on a project to that will use Pd running on a Raspberry Pi, and that will generate control voltages using DACs (ideally something like a MCP4922 or similar, <a href="http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en020399">http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en020399</a> ).</div><div><br></div><div>I know about Miller's gpio external, found here: <a href="http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm">http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm</a> , but it does not do any of the SPI interfacing, which is the way that will need to interface with the DACs.</div><div><br></div><div>Is there any possibility (Miller or anyone smarter than I am on this stuff) to extend the gpio external to include SPI interfacing?</div><div><br></div><div>Thanks in advance,</div><div>Dan</div><div><div>-- </div><div>Dan Nigrin / Defective Records / <a href="http://defectiverecords.com">http://defectiverecords.com</a> </div><div>CycliC, M185 & Klee Sequencers / MC-4 & MC-202 Hack / Audio Plugin Player / General MIDI Player / Major Malfunction</div><div>Jack OS X / <a href="http://jackosx.com">http://jackosx.com</a> </div></div></div></div></body></html>
