Hi Everyone,

I am trying to use a 6i25 - 7i77 - Cheap Breakout board.
I did this before with a 7i76e, and used 7i76e_bstech.bit... or something similar. I'm using a 6i25, and from the 6i25 I want to connect to a 7i77(and up to here, all is okay), and a Breakout board, to control a spindle position/index control/C-Axis which requires 5v Step/Dir.
I loaded the following firmware: 5i25_7i77_bstech.bit.
This gives me the following pins availailable:
hm2_5i25.0.stepgen.00.control-type
-velocity-fb
-velocity-cmd
-position-fb
-position-cmd
-enable
-dbg_vel_error
-dbg_step_rate
-dbg_s_to_match
-dbg_pos_minus_prev_
-dbg_ff_vel
-dbg_err_at_match
-counts.

I don't see the following:
-position-scale
-steplen
-stepspace
-dirhold
-dirsetup

Please advice if I should use different firmware, and what firmware I should use for this setup.

Those are parameters, not pins, and will be present for any configuration that has step generators

Hi Peter.

Thanks for your reply.

Okay, My Bad... You're right... I'm going to try this again. Will let you know on the progress. Not sure what I did wrong on friday(actually, the problem was that it was friday, ... :D), but Linuxcnc is starting up now, and ... I need to test it, and will give feedback soon.
