7i96 Configuration Tool Questions

I've just added the read of the firmware to the above post, in case that helps.

The 7i96_7i85s firmware does not actually have a PWMgen
(its got an error in that it reports having one)

Here is a 7I96 +7I85S bitfile with a PWMgen replacing
Stepgen 4 on the 7I96

No, because the 7I85S is a passive device (just signal conditioning)
but you will have 4 encoders (a total of 5 including the one on the 7I96)
and 2 or 3 additional stepgens plus 1 more sserial port

I've flashed that bit file and I now have PWM. Thanks Pete. The VFD's speed is jumping all over the place but I suspect that is just noise as I've only used a twisted pair and not screened cable. I'll change the cable and hopefully that will resolve that.

Unfortunately I've still not got anything registering on the encoder input on the 7i96. The config tool still only gives the option for a single encoder, it won't let me increase above 1, but given I can't get the first one functioning I'm not particularly worried about that just yet.

Note that the encoders are numbered:

7I85S Encoders 0..3
7I96 encoder 4
