7i95 board for 5ABoB(not T or S) firmware missing

The inputs already work.
That number of stepgens will not fit a standard 7I95 configuration
Do you use all the encoder channels?
Do you use the sserial channels?
(The added stepgens might fit by eliminating unused features)

I need stepgens on 2 (step) 3 (direction) , 4 (step) 5 (direction), 6 (step) 7 (direction), 10 11 15 pins as inputs for the pins of 5 Abob.

Struggling to get all encoders to show up on 7i77 via 7i94T was created by workshop54
Struggling to get all encoders to show up on 7i77 via 7i94T
Category: Driver Boards
I've been working on this all day and it's starting to drive me a bit crazy.
I'm using a 7i77 connected through a 7i94T and trying to get at least 3 of the encoders to show up in halcmd show pin. So far, only two encoders are visible.
Here’s what I see:
I’ve double-checked the firmware:
My HAL config includes:
The SmartSerial section seems to be working fine; analog IOs and digital IOs show up correctly.
But I expected more encoders from the 7i77 to appear — at least enc2..enc4 — and I can’t figure out what I’m missing. Is there anything I need to change in the firmware, or is my HAL config wrong?
Any help would be very appreciated. I’m just trying to get basic encoder feedback working for now before wiring up the rest.
Thanks in advance!
