Just looking at the commit.
The meat of it is lines 113-192.
So you have created two DB25's with just GPIO_0?
GPIO_1 is unused, or its pure GPIO (this is what disabled the "special
function" I/O looks like)?
Line 112, 133, 154 shows DB25-P2, three P2?
Line 175 shows DB25-P3
Line 115, 118, 119, 122, 124 are StepGenStepPin, five of those?
Line 117, 121, 123, 125 are StepGenDirPin
With this config which pins would I use for GPIO, GPIO_1 (LCD, relay,
VFD, pendant, limits, T.O.P)?
Line 114 is PWMAOutPin, what is that to connect to Pulse Width
Modulation right, maybe for a VFD for the spindle?
Because I only need four steppers and one encoder should I just make
lines 134-150 the same as lines 155-171?
Would you know of a reference guide that shows the format, syntax and
what the special function are in these vhd files?
Thanks again, I'm learning a lot!
