Question on MESA boards config was created by Ameone
Hello everyone,
I have a set-up consisting of a MESA 7i80-DB connected to two daughtercards, 7i76 for stepper motor control + a 7i85 additional board. I would like to add a third board, MESA 7i87, to read some analog sensors.
Do you know if this is possible or not? Is there a LinuxCNC firmware for this configuration?

Do double check this, but it should be possible to just wire the 7i87 to 7i76 using a cut off LAN cable, the Smart Serial connector, info on exact wiring is on the 7i76 manual.

There's 7I76+7I85S firmware for a 7I80DB but not for the 7I76+7I85.
I can make this if you tell me which version of the 7I80DB you have (-16 or -25)
Note that Sserial cards don't need any card specific support in the firmware.
(as long as there is a sserial port, any sserial card is supported)
The 7I76 has 1 free sserial port and the 7I85 has 5 free sserial ports.

Ok if the card doesn't need any specific firmware, then it's fine, I already have the bit file for the other cards. Is there some specific settings i should add to the hal/ini files for it to work?

You _do_ need specific firmware for the 7I80DB with 7I76+7I85 daughtercards
If you have this, any serial card is supported.
In case you do not have 7I80DB 7I76_7I85 firmware, here it is:
