Greetings;

I have now written the 5i25_7i76_7i78.bit file to 3 different
5i25's, the one that has been in the machine for several years, and
2 of the 3 Peter sent me in about 2015.

none of them will admit there is a pwmgen feeding P3, all show the
first one feeding p2. But there are 2 listed in the corresponding
.pin file, and with the 5i25_7i76_1px2d.bit file installed, the
first one replaces stepgen #4 on p3. But with that firmware, I have
no pwmgen.01.dir on p2.

There would normally not be a PWMGen on a 7I76 interface
Except for specific firmware that replaces the stepgen with a PWMGen
Like the 5i25_7i76_1px2d.bit. The 7I78 will always have a PWMGen for
its spindle interface.

But now I need a 2nd pwmgen, which with the other 5i25_7i76_1px2d.bit
file installed comes out where stepgen4 would be.  But there is no dir
from the 2nd one on p2 with that bit file installed.  So I'm screwed
either way,

Can you fix the 5i25_7i76_1px2d.bit to make it work with 2 active,
independent pwmgen's? Or, since that bit file is old, has it been fixed?
But that file does not exist in the latest 5i25.zip. If you can take
that old file and make the 2nd pwmgen on p2 work, that would be the
simplest fix for me. A pair of complementary dir's would be the icing on
the cake.  That would allow it to control a full H bridge.

"1p" indicates that it just has 1 PWMGen

Also that bitfile does not seem to be in the current distribution

What do you actually need?

Are you sure you need complmentary directions
(That is will the up/dowm PWM mode work?)



Thanks Peter.

I have a 5i25, with a 7i76D on p3. and a std bob on p2.

What do I do next besides fix dinner and take a nap? Wake up and see
if I can make the 420 watt audio amp work.

Thanks.

Cheers, Gene Heskett
