Mesa 7I96S + 7I85S Bitfile

Actually this is my fault, the correct firmware file is

7i96s_7i85sd.bin

(not .bit)

This is in the

hostmot2/configs/

subdirectory

ha ok, I've often fallen over the bin files. When I open the appropriate pin file, I unfortunately notice that the config is for 4 axes and 2 encoders. do i see that correctly plus 1 rs tx. As for the 7I85S.

I need 3 axes and 3 encoders on the 7I85S. is there also a suitable config?

because I would like to bring my milling spindle encoder back and then an xyz glass scale.

the milling spindle is a servo that i would like to control via step dir.

and thanks for the help

which I still don't quite understand. when i try to create a bin file myself in ise 14.7, it always tells me error in synthesize? even if i try other packets from other mesa cards

The 7i96s_7i85sd.bin configuration has:

9 step/dir channels (5 on 7I96 and 4 on 7I85S)
2 sserial channels (1 on 7I96S and 1 on 7I85S)
5 encoders (1 on 7I96s and 4 on 7I85S)

Note that the encoders are multiplexed so each interface pin
supports 2 encoder pins.

The 7I96S uses an Efinix FPGA so you would need the
Efinix tool chain to make firmware for the 7i96S.

First of all, that sounds even better than what I wanted, and secondly, I don't quite understand the thing about the pins. I also have old Heidenhein glass scales that I believe are the difference and not ttl. is it also possible to mix?

the glass scales have 8 pins, 2 of which are for 5v and gnd.

Yes, the 7I85S can interface to 4 encoders, individually selectable
as TTL or differential.
