[Emc-users] BBB LinuxCNC again
I struggled in the last couple of weeks to get some more out of the BBB +
LinuxCNC setup, mainly the display part was suboptimal.
my setup
---
bbb connected through the USB (and eth tunnelled over that - 192.168.7.2) to a
laptop (192.168.7.1).
1. laptop running Linux
There were some performance issues with running AXIS (especially the OpenGL
part).
Here are some comments from jepler which improve things:
{[01:04:32]} jepler this makes it use the glx wire protocol instead: sudo
chmod 000 /usr/lib/arm-linux-gnueabihf/dri/swrast_dri.so
{[01:14:15]} jepler changing the task timeout to 10ms instead of 1ms knocks
milltask way down
{[01:14:45]} jepler ssh encryption takes 30% CPU
{[01:27:26]} jepler this seems to be a bit lighter on the CPU: ssh -X -o
Ciphers=arcfour linuxcnc@192.168.7.2
2. laptop running Win
I played around with a couple X servers (Cygwin/X, Mingw+X, Xming) but the best
results I got with Xming-mesa.
For Xming-mesa I still had to have the swrast_dri.so accessible (sudo chmod 644
/usr/lib/arm-linux-gnueabihf/dri/swrast_dri.so) in order for things to work.
here’s a short video how it works:
http://www.youtube.com/watch?v=ZuE1JWFbbOU
There is a prebuilt image available for download here:
http://webshop.juve.ro/index.php?main_page=product_infocPath=1_5products_id=7
The image contains the latest Machinekit I got from Charles, and can be written
directly to a SD card with dd.
On the image (in the fat partition) there are some additional programs
installed:
- Xming-mesa server (run-in-place version)
- putty
- a simple batch file (start.bat) which starts up the X server, connects to the
BBB, and starts the LinuxCNC config picker
Hope this helps someone else out there

Impressive results! The backplot display actually looks like it might
be usable (at least when you didn't just load a 10 MB 3D print file with
a few hundred thousand lines of gcode).
Note that you can also use the null cipher (no encryption) with ssh, but
you have to coerce both ends into allowing this. You can also just
forward the raw X display without tunneling (I've verified this with the
Cygwin X server, but I haven't tried it with swrast_dri.so fix).
Thanks for sharing!

Re: [Emc-users] BBB LinuxCNC.
I am certainly planning on using the BBB PRU directly for some of my projects, but I have others that need to control ten stepper motors, or do closed loop servo control of four axes with high resolution encoders. I don't think the PRU can handle that many channels, although I could simply be insufficiently educated on its capabilities. I already have a half-dozen 7I43's, with a lot of configuration work for my projects already done. So in my opinion this is not such a silly scenario. Any processor can benefit from an FPGA assistant :-). -- Ralph From: andy pugh [bodge...@gmail.com] Sent: Friday, October 11, 2013 3:22 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] BBB LinuxCNC.

I don't think the PRU can handle that many channels Well, in that case I guess that what is needed is some code (possibly running in the PRU) to buffer a byte stream onto a selection of pins, and read back on others to act like EPP, as was suggested. On the HAL side it looks moderately straightforward, a third interface driver to live alongside hm2_pci, hm2_7i43 and hm2_eth (arguably hm2_7i43 should have been called hm2_epp). hm2_bbb could even conceivably be a base-thread HAL module and simply twiddle GPIO bits.

The hm2_7i43 driver has the right name, because it has a bunch of 7i43-specific stuff in it. There's another EPP AnyIO board now called the 7i90, and it needs a different driver than hm2_7i43 because it needs to be talked to in a different way, and unlike all the PCI AnyIO cards there's no way to tell the difference between them 7i43 and the 7i90. What would probably make sense is to pull the EPP code out of hm2_7i43, and while we're at it look at what other EPP-using drivers there are, and unify all that. Then hm2_7i43 and hm2_7i90 (and the others) can use this new EPP driver. And *then*, we can make that EPP driver pluggable so we can drop a BBB/PRU EPP driver in, and have it export the same interface to the higher-level drivers, and then both 7i43 and 7i90, and whatever other EPP-using drivers we have, would work. hm2_bbb could even conceivably be a base-thread HAL module and simply twiddle GPIO bits. That'd be too slow for hm2 EPP communication. The EPP protocol needs several control-line twiddles, and polling for incoming signals from the device at the other end of the cable, per byte transfered: http://www.fapo.com/eppmode.htm However, if it were to be presented as a parallel port (as far as LinuxCNC saw it) instead then it would also work with the Pico cards. We could provide compatibility either at the IO port level, or at the API level as i outlined above. I think either one could be made to work. -- Sebastian Kuzminsky -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.

This is _maybe_ possible using just the BBB and the PRU, but using something like the 7i43 means a lot less development work. Yes, exactly. Something I really want to do is create PRU code and hack my PPMC driver to talk through the PRU for fast access to the external device. Later I might create firmware for these devices with streamlined I/O to allow faster servo cycles. The PRU is great for step generation, but when faced with having to sample multiple hardware encoders at high speeds as well as create PWM or analog outputs with high resolution, it runs out of gas.

Actually, in this _specific_ scenario I suspect that EPP emulation on the BBB to talk to the FPGA is possibly a silly thing anyway, because what is happening in the FPGA is GPIO emulating EPP. It is possibly more sensible to just set up a fast serial link from BBB to 7i43, and use a different firmware on the FPGA that doesn't waste effort trying to be a parallel port. The 7i43 specifically is pretty well tied to EPP due to the CPLD that receives the FPGA firmware via EPP and flashes the FPGA. Possibly a future AnyIO board won't have this requirement. Or maybe we could do slow EPP by software-twiddling the GPIO pins to send the firmware, then do some smarter/simpler serial protocol over the same wires once the FPGA firware is in control. -- Sebastian Kuzminsky -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.

Did I need a cape? Could I just connect to conventional drivers like a parallel port? Do I need to solder wires on or is there a screw type connector that fits the sockets? It wasn't obvious.

Re: [Emc-users] BBB LinuxCNC.
Careful...this is not a PC parallel port. At the moment, there is no software to talk to anything like a Mesa 7143 via an emulated EPP port via the BeagleBone. That doesn't mean I wouldn't _like_ to see something like this. I actually have plans to do this at some point, but it will almost certainly require a different pinout and a different circuit board. The step/dir GPIO pins can be pretty much randomly assigned to any free pin, but implementing an emulated EPP interafce to talk to smart hardware requires a bit more planning.

I am kind of like Ralph. I also have a Mesa 7i43 that I would like to be able to run from a BBB. It would be great if there was a cape that could look like an EPP with a driver that could run hostmot2. I have one machine that I am going to try to run from the BBB + BeBoPr + Bridge. But eventually I would like to use my 7i43 with a BBB or, if Pete comes up with the equivalent of a 5i25 for the BBB, sell my 7i43 and the two 7i42TAs that I have.
