Problem with 7i80db_16_7i76x2_7i77x2D

I have one 7i80db 16, one 7i77 and I actually don't have a 7i76 card. I only need one hardware stepgen for the toolchanger and my plan was to use this config for that and just add two optocouplers to the output pins on the 7i80. I also have a 7i73, but that is not connected yet.

About a month ago I tried to make a new bitfile, just to add the stepgen. I compiled the 7i77 x 4 source first without any changes but I never got it to work so I waited to try the software stepgen first. Then I found out that the m7i76, 7i77 should work but it has not so far.

give this bitfle a try
freeby.mesanet.com/7i80db16_7i76x2_7i77x1D.bit

(7I77 I/O numbering will be different )

We are almost there. Communication works with that one!

Only problem with this is that analog pins are missing
hm2_7i80.0.7i77.0.7.analogout0-scalemax for instance.

I attach a textfile with show pin.

I had the sserial port order wrong in that config
try fetching it again

(7i77 ports will be 4 for DIO and 5 for analog)

And now it works. You are a hero!!!

Thanks Peter.

Today I have tested with the steppermotor and the carousel and I just wanted to give some feedback and tell it works perfect!
