Mesa 7i39+5i20 was created by karl1
I just recievied a pair of Mesa 7i39 today; just looking for anyone who may give their input or expirences with these cards. I already have a 5i20 and 7i33T. I planned on using the 7i33 with some servo amps I already had, but couldn't use them with the motors I since aquired. I had the 7i33 hooked to encoders only, for these motors and tested with the HAL pyvcp 5i20 test panel that Anders Wallin created. All is OK. Any advice?

The 7I39 is not currently supported by EMC, I do have a firmware configuration that will drive a 7I39 but the HostMot2 driver
would need work to support the three phase PWM generator module, and a HAL component would probably be needed to generate the proper drive

it would be nice to get motors to turn soon; I would be willing, as a non-programmer and new to linux, to try anything. I have several computers that I could throw the 5i20 card into, be it linux or windows. Any suggestions?

I have now got this configuration working. It requires the latest development version of the Hostmot2 driver and a HAL component that I hope will be committed soon. (but could be made available separately)

Hello,

I am also trying to configure emc2 (ubuntu10.04 with emc2.4),
to work with 5i20 and 7i39.

Do you have a working system with 5i20-7i39 ?

If yes, could you share the configuration?

Regards,
Nikos Chalikias

You will need the 2.5~pre version of EMC2 as the necessary drivers are not included in 2.4.
A version of the Hostmot2 driver which supports tp_pwmgen and the bldc_sine and/or bldc_hall components will be needed.
You will also need one of the Three-Phase PWM-enabled .BIT files for the FPGA board.

I believe that all these are currently included in the 2.5 version, but you will need to download and compile that in order to use it.

You will need to follow steps 2.1.2, 2.2 and 2.4 at this page as a minimum.
wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
Don't neglect step 2.7 which instructs the system to use your new version.

Documentation for the new features is here:
www.linuxcnc.org/docview/devel/html//man/man9/hostmot2.9.html (especially the "config modparam" section and "3pwmgen"
www.linuxcnc.org/docview/devel/html//man/man9/bldc_hall3.9.html
www.linuxcnc.org/docview/devel/html//man/man9/bldc_sine.9.html

And for proof that it does really work:

Hello Andy,

Thank you for instructions.
I followed steps 2.1.2 2.2 2.4 2.7 All successfully.

I run emc as suggested in 2.7 and emc script directs to /emc2-dev

EMC2.4.4 starts instead EMC2.5 !!!!!

Please advise how to get the right version

Regards,
Nikos

The emc-environment script changes things in the context of the currently-open terminal window only. You need to start emc2-dev from the terninal by typing emc.

If you start from the menu / icon then it still starts the 2.4 version. (You can change the shortcuts to point to the script called "emc" in the emc2-dev directory if you wish)

I run emc script from terminal from /emc2-dev/scripts/, exactly as described in section 2.7
I do not run from the menu.

I have also checked the emc script with the gedit and seems OK, pointing to /emc2-dev/

The file named VERSION inside /emc2-dev/ contains : 2.4.4

My conclusion is that inside /emc2-dev/, it is installed version v2.4.4.

What is the exact way to get EMC 2.5 with GIT?

Ah, bother! I just noticed that the instructions specifically tell you how to get v2.4.
Sorry about that.

git checkout master

Might well do the trick. (I am really no expert with git)
