Thanks, Andy, I'll try that. Compiling firmware isn't a problem. I do have two different projects going on at the moment, but I'll probably shelve the effort to fix the slight annoyance of restarting axis to get the bldc to reinitialize.
I may have some more questions about setting up the bspi registers once I get the firmware compiled. -- Ralph ________________________________________ From: andy pugh [[email protected]] Sent: Wednesday, July 23, 2014 6:38 PM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] hostmot2 spi On 24 July 2014 02:26, Ralph Stirling <[email protected]> wrote: > The wiki mentions that these might be available in 2.6, and I see > a bspi.c file in the 2.5 drivers, but don't find much documentation > or indication of how it works.

(It isn't all that hard to build a firmware, but might be more than you want to take on given the other irons you appear to have in the fire). If you load that firmware then a "hook" will be created into the hostmot2 driver that will let you access the registers and work with them. Look at src/hal/drivers/mesa_7i65.comp for an example of a comp that works with BSPI. A quick way to get started might be to find a 7i65 firmware for the 7i43. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
