I have 5i25 and 7i78 mesa cards but in Pncconf I not found support for this cards. How I can to solve this problem?thanks

You can build the HAL file by hand. I prefer doing it that way and it isn't all that difficult (though it is slightly tedious)

You need a list of the 7i78 pins, which can be obtained by following the instructions here:
www.linuxcnc.org/index.php/english/compo...id=49&id=21529#21540

You can then edit them into one of the sample Hostmot2 configurations.

The 7i78 is a cut-down 7i76, so you could just follow the instructions elsewhere for configuring a 7i76 in pncconf and change the names afterwards.

In the 5i25 manual in the section "supplied configurations" say that 7i78x2 is supplied for mesa is this true? In 7i78x2 say that 7i78 configuration have two pwm and gpio but 7i76 dont have pwm output and I need pwm outputs.

The PWM output may drive the spindle speed analogue output.

I could re-flash my 6i25 with the 7i78x2 firmware, but that would be slightly awkward at the moment.

PCW probably knows the answer, but might not be around at the moment.

If you open a console and type:
halrun
loadrt hostmot2
loadrt hm2_pci
exit
dmesg

Do you see any mention of PWM outputs?
