Hmm, makes sense.

I hadn't considered that, thanks. And it works. Lots and lots of i/o.
Saved and printed. Should be helpfull but will need translation from
gpio-nn to tb-#-# to use. Go feed the missus and input some more coffee
and get to it, starting with getting the other bob for 5i25-p2 powered.
Looks like this will get me going as soon as another standoff kit gets
here, promised tomorrow evening. The box is 3" tall, so I'll mount the
cards about 2" high, and take all the cableing to the machine out under
the boards, so the terminals are not buried in wire. And I'll have a
kajillion of these to fix:
twopass: Error in file ./GO704fast.hal:
setting parameter 'hm2_5i25.0.gpio.007.is_output' to 'true'
parameter or pin 'hm2_5i25.0.gpio.007.is_output' not found
Hmmm, ack that printout, it almost exist, but is_output does not, only
invert and open_drain. Since that is also the stepgen #3 step output,
that line can be nuked in favor of an open_drain, which is how I've
driven the steppers anyway.
I take it the ability to change a gpio's direction was lost in the 7i76?
Abd I just discovered that none of the 7i76 stuffs made it to the save
all output. I guess I'll toss these printouts and make the pin file with
screen copy pasted to geany, which added 60 more lines to the printout.
Laborious, but I'll get there.
Thank you Peter. Now for that 2nd cuppa. And feed the missus. Then make
more coffee, this is yesterdays leftovers. :)
