Re: [Emc-developers] 7i80 support

[sam s. <sa...@em...>]

Ok - so I had a little more time to play with this..

micges was wondering what hardware I was using.

intel pro/100 with a asus FiA55-m LX plus motherboard.

I tested the setup one more time as is - still got encoder errors and 
watchdog bites.  I was looking for another nic - maybe a intel 1000 or 
other supported rtnet nic.  I did find a pro/100 that was quite a few 
generations newer.  I though - what the heck.

Well that seemed to help quite a bit.  Using the setup below I didn't 
get any watchdog bites or encoder errors. Yay!

the issue seemed to be now that no matter what I told the 7i80 I wanted 
- it always gave me 6 encoders and 6 pwmgens.  The config seemed to not 
be sent to the board.

Jeff E took a look and found one error and made this patch

This seemed to fix it so I could have 0 of everything (only gpio) The 
only issue now seems to be that I can tell how many pwm or encoder I 
want - but nothing else.

So if I do a config="num_encoders=1 num_pwmgens=1 num_stepgens=1 
num_3pwmgen=4"

I get 1 encoder and 1 pwm

here is the linuxcnc.log and the resulting show

So - very close!!  Exciting!
