I don't get it. I should think the the PI would be a darling computer to use for LinuxCNC, though there's no official RasperianCNC distro.
Apparently, someone has the kernel all patched up, already.
It would be cool it there were a standard IO board for CNC and Pi use which would include:
* A Realtime clock and battery, which are necessary as it's not a good idea to have a CNC cutting machine facing the web in most instances.
* Transistors to operate opto-isolators to protect the I/O.
It looks like excluding the two-wire pins, and the serial port pins, there are 22 remaining.
I6 outputs and 7 inputs?
Are there some other RPi pin conventions I am missing?
Which is better than a parallel interface, is it not?
Thanks for any input. This looks like one of the coolest things I would want a Pi for.
