You probably have tabs on that line instead of spaces.

"EDIT"  My bad, I jumped the gun and didn't pay attention that it was PWM... I saw the EL25"" models and responded too quiickly, yeah I am supprised there isn't any either...

Yes, there are pulse train terminals in the code already and have been for years.  Look for EL2521 models.  I have these and they work.

If you bought some other terminal, then here is the code to the 2521 so you can have something to work from.

Also, those EL4032's are 12bit, the 4132's are 16 for when you are looking in the future.  The 4134 is also in the code for the last few years if you need to maximize terminal space...

Follow either of these two links and in the first post go down to PART 6 - LET’S SEE ETHERCAT WORK IN THE REAL WORLD .  There are detailed instructions on how to do the external Stop button and you should see how to do a start button also.

Thanks for your answer.
But Linuxcnc will coming up with an error:

 
 

hey scott, ive been playing with it for the last 2 weeks. I dont have much to show, but i think the environment switching is working kinda. im testing with a nucleoh743, from the debug it seems to be working but serial is messed, it seems i dont know how to do a define or something,

github.com/cakeslob/Remora-STM32H7xx-PIO...43/Src/main.cpp#L116

im not an expert but i think thats exactly what its supposed to look like (rpm changing as diameter changes). assuming those portions that are the straight lines are in between jog moves. I didnt see (or hear) any weird spindle speed drop outs like before thought. i am assuming you figured out the issue?
