yes, the others are catching up ;) > > given the beagle has a PRU, why couple it with an additional FPGA ? > Sounds like what we really need is just a linuxcnc driver for the PRU > firmware developed for the project above... That's already in place for several months, and it's the reason why the BB works disproportionally well as soft stepper generator (relative to it's CPU bang). You find Charles's great work here: http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=tree;f=src/hal/drivers/hal_pru_generic;h=5e7dc56c1891408833362fd7f480a9da20dcc31d;hb=b45ce813cc7b76b1f35e60b116a7f8a02e002703 and here: http://bb-lcnc.blogspot.co.at/ - Michael > > Bruno > > On 2/13/14 4:01 PM, [email protected] wrote: >> Date: Wed, 12 Feb 2014 14:19:45 -0600 >> From: Charles Steinkuehler<[email protected]> >> Subject: Re: [Emc-developers] usage of get_rtapi_config on machinekit? >> To: EMC developers<[email protected]> >> Message-ID:<[email protected]> >> Content-Type: text/plain; charset="iso-8859-1" >> >> On 2/12/2014 11:41 AM, W.
