Successful stepconf user buys Mesa5i25 wants to use experience in pncconf. How??

What files you need to edit depends on the use of the other G540.
If the other G540 is used to drive other joints/axis you will need to
edit both the hal and ini files to setup the other joints/axis

"num" probably refers to the stepgen/pwmgen/gpio instance

About the HAL, that's what I was thinking/hoping.

I thought that, too about the "Num" column. But the numbers go as high as 33.

Also, what would be the difference between Num 000 and Num 0 ?

Both can't be an instance of zero, can they?

num = number of

I think pncconf uses the hal pin instance field name so
things like GPIO pins might have 3 digits but other hardware
might have only 1 or 2.
