If I spend one more minute thinking or writing about copyright and licensing issues I'm going to give myself a brain tumor, so I'd like to do something useful for a change :)
GP Orcullo has got a project (PICnc) where he attaches a PIC32 "auxiliary processor" to linuxcnc on a Raspberry Pi through the RPi's SPI interface: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=37&t=33809 (his writeup on linuxcnc for the RPi is also invaluable): http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RaspbianXenomaiBuild I'd like to do something similar, but using an FPGA in place of the PIC32 to create the equivalent of a Mesa 5|6i25 for the RPi. I know Peter at Mesa has some plans for an SPI version of his "Anything I/O" system, and we'll need an hm2_rpspi component to use it in linuxcnc. The PICnc project (above) has code that demonstrates the use of the SPI on the RPi. Is anyone else working on hostmot2 over spi? If not, does anyone have any advise or pointers on how to go about this? My best guess is to look at the difference between hm2_pci and hm2_7i43 and then insert some SPI related code to change the physical interface. Any thoughts on this idea are appreciated!
