Yep that looks like a 7I76+7I78 configuration
with just one PWMGen for the 7I78 on P2
but this is the load line that generated that dmesg:
loadrt hm2_pci config="num_encoders=2 num_pwmgens=2
num_stepgens=3"
Thats a pinout file not a dmesg log
Its the output of the --readhmid command you asked for. I just
copy pasted it all, including the mesaflash command you can see at
the top of the paste.
the dmesg file shows the 2nd pwmgen, but the dir signal is
permanently grounded.
Thats with the original 5i25_7i76_1px2d.bit file installed.
Um no, there is only PWM 0 brought out
What pin is grounded?
P2-05. With the 5i25_7i76_1px2d.bit bitfile installed, 3 5i25's
tested.
Thats expected to be low since its PWM 0 PWM pin
Not according to the docs or dmesg, pwm is pin 6 and is the pwm
waveform on the scope, pin 5 is supposed to be its dir, and high
for a - input. Its stuck on ground regardless of the polarity of
pwmgen's input. As of testing yesterday on 3 different 5i25 cards.
OK I though you were still using the 7I76_7I78 config sorry
To demo, I just rewrote the 5i25_7i76_1px2d.bit file back into the card,
verified it, and reloaded it. Ran linuxcnc -l with this loadrt line:
loadrt hm2_pci config="num_encoders=2 num_pwmgens=2 num_stepgens=3"
then ran dmesg and got this:

All I want and need is for both of the 2 pwmgen's I can see above to
actually work. In my original .hal file, I had to parallel both pwmgens
to get enough signals to run the spindle.
But now I need both pwmgen's to be independent and fully functional.
pwmgen #1 dir on p2-05 doesn't work, welded to ground. In fact
neither DIR can be seen to be working on a halmeter. But at 4AM I'm
not going out in my fruits to check it with a scope.
If thats the case there is a configuration error or hardware problem
There is no reason the direction signals should not work
Have you set the PWM mode correctly and tried setting the PWM value by hand?
I can probably dummy up something in hal to replace it, and I need this
machine running to make the rest of the BS-1 motor kit so I'll try as
I've got gpio to spare on p2 yet. But if stepgen4 is removed, which
I'll not need, then there s/b room to make both pwmgen's work.
Stepgen 4 on P3 is already removed (its replaced by PWMGen 0)
That would turn 5i25_7i76_1px2d.bit into 5i25_7i76_2px2d.bit by your
naming convention. And that would still leave enough stepgens to run
my 6040 mill with that same 2px2d bitfile. So in the very helpfull
category, would be a .pin file for every .bit file. :) But there is not.
Can that bit file mod be done? Take out stepgen #4, and make both
pwmgen's work? With pwmgen.00 outputs on the 7i76D tb3 in place of
stepgen#4, and pwmgen.01 working on the advertised pins of p2, I'd be
a happy camper.
The alternative would appear to be a 7i90 ($59) and 3 7i42TA's ($135)
plus a bunch of cable connectors for 50 pin ribbon per parport socket
since no one has made an actually working spi interface for wintel
stuff. That works great on a rpi4 in SPI mode. But thats over $200 too.
UNK how well it would work on a parport with 4 feet of input cable.
Its spi cable is only 2" including bus adaptor on the pi's.
It does seem to have a harmless inconsistency
(2 PWMgen inside but only 1 wired to the output)
