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 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?

PCW OFFLINE Moderator Posts: 1718 Thank you received: 92 Karma: 116	The 7I78x2 config has 2 PWM outputs (one for the spindle analog output circuit on each 7I78) there no reason that a new configuration could not be made with one of the 4 STEP/DIR output pairs sacrificed to give a couple more 5V buffered PWM outputs

cmorley OFFLINE Moderator Posts: 1520 Thank you received: 41 Karma: 89	unfortunately I need add the pin names of the 7i78 into pncconf so the XML file will not help you. If someone could post the HAL pin and param names for the 7i78 that would be great. Chris M

PCW OFFLINE Moderator Posts: 1718 Thank you received: 92 Karma: 116	The 7I78 is very basic with 4 stepgens 1 PWM (for spindle analog) 1 encoder 1 sserial (expansion, theres no I/O on the 7I78 except whats listed)) so the 7i78x2 config has ths set of I/O on both connectors freeby.mesanet.com/7i78x2.pin has the pinout
