Mesa 7i95

Here they are:

Thanks Peter - unfortunately it has more then 50 pins so it will require extensive code changes - may be awhile to get this one done.

Hi Peter,

Just make sure you have common grounds before you connect signals

To be clear, you're suggesting a software based PWM instead of a hardware based 'pwmgen' ? or am I missing something about setting modes on the GPIO pins on P1.

I'd prefer to use a hardware pwmgen if thats possible.

Cheers!

7I95 config with PWM on pin 1 of expansion connector

Thanks very much Peter!

I noticed a problem with the 7i95 input / input-not pins in LinuxCNC 2.9 latest version. They normally flip-flop.

input-00 low
input-00-not high

input-00 high
input-00-not low

but input-xx-not stays low all the time.
