The pinout is determined by the firmware so many
parallel port type 7I92 bitfiles will do
Does this mean that say stepgen 0 is tied to pin 2 and 3 (on db25) and
so on?
How do I get my pin number allocation as I set it out below. I seem to
not be able dictate how the stepgens are assigned to axis.
For example 7i92_5ABOBx2D.bit firmware will work here
I tried this first off but had no luck with getting any output so I
moved to the 7i92_G540x2D.bit
You associate stepgen numbers to Axis in pncconf
Herein lies the problem (mine) I cannot get to arrange them as I want.
The assignments seem to jump around. I get the first two stepgens
assigned correctly. X axis and its slave to pins 2/3 and 4/5 - stepgen 0
and 1. The rest keeps changing if I want to arrange them in my order. So
if I only need to swap Z and A to get the correct assignments, then
there would be another stepgen assigned to the slave axis of X. I don't
seem to be able to make sense of it.
The firmware maps those numbered stepgens to
physical pins
XSTEP - 2 : XDIR -3
X2STEP - 4 : X2DIR - 5
YSTEP - 6 : YDIR - 7
NO Z (or 16 and 17)
ASTEP - 8 : ADIR 9

Seems to be coming through blank.
