Mesa 7i96s firmware for Index (2.9 release)

Yes please
Is there a way to see how you do (screenshot or whatever) in order to learn a bit also?

Here is 7i96s firmware that adds a stepgen index pin for all stepgens

Note that these have been added to the P1 expansion connector
so can only be used with TTL/5V level index signals. It's also advisable
to add a say 220 Ohm series resistor to each input if interfacing
machine I/O to the P1 FPGA expansion port to protect against negative
input spikes.

 
 

Thanks a lot I will first check what you modified in order to understand and confirm no other impact on my setup and then flash the firmware

Thank you again.

I struggle with the configuration
If I understand well I need to adapt this line in my Hal file but can't figure what should I put?

net xindex-enable axis.0.index-enable <=> hm2_7i96s ???
I connected my index on i/o 36 (P1)
Thank you for your help

It connects to the hardware stepgen index pin
probably something like:

hm2_7i96s.0.stepgen.00.index-enable

halcmd show pin hm2 | grep index
 (when linuxcnc is running)

should list it

Here is the output of the command:

    38  bit   IN          FALSE  hm2_7i96s.0.stepgen.01.index-invert

and the end of my readhmid

I connected normal input on IO 34 qnd 35, it works fine. But how should I tell the system the stepgen index for axis X is on the 36 and for the axis z on the 37 ?
