hostmot2 oneshot bitfile help

Well I guess I give up on this...

It works for me on three different hardware setups: 7I96S, 7I96, 7I92
(and even different FPGA families)

Only thing I can think is you are not running the firmware I sent or you
have a bad 7I92 with a FPGA issue (which is not something I have ever seen before)
or there is some other hardware specific issue with your setup.

I use your firmware.

Today I tested with a 5i25 and an other, older 7i76. It works perfectly with it.

Then I tested it again with the 7i92. For this I created a minimal setup. All disturbing devices (servo-drives, vfd...) were switched off. But with the 7i92 it does not work properly. I also give it up.

Sorry for the rant and sorry for the issue. I think its fixed...

My tests ran perfectly because I was using perfect signals...

As soon as I introduced some noise, I could duplicate your issue.

The issue was a metastable on the external input sampling

 

 

It works now
Thank you very much!

It runs on the 7i92 in the Cabinet:
 
 

Sorry it took so long to figure out and fix...

hi all,
would I need a special bit-file to set up a 6-axis-robot like the vismach/puma560 using RC-servos (rcpwmgen) and the mesa 7i76e together with the 7i85s (9x stegens and 5x encoder inputs in total)?
How can I create such a bit-file by myself? What would be a good starting point?
If I don't need one, how can I connect the three leads from the servos?
Cheers.
Martin.
