7i96 Can't get PWM output was created by jools
Hi all
I'm having real trouble trying to sort out a PWM output on my 7I96 and have spent the last two days trying different things with no success and desperately need help.
The back story is my first configuration with the 7i96 configuration tool kindly made by John produced a working configuration but there were no manual spindle speed control buttons showing in Axis. I added some net commands in the HAL and they appeared but would still not output a PWM signal to the Mesa card. The voltage at the pins stayed at -5v.
I had added things so much to that configuration that I just deleted it and started a new configuration with the 7i96 tool.
This caused more problems. Currently LCNC refuses to load and gives the error:./io.hal:7: Pin 'motion.spindle-forward' does not exist
In the IO.hal file I found the below
net spindle-cw motion.spindle-forward => hm2_7i96.0.ssr.00.out-00
This suggests to me that I need to link some sort of button on Axis that's called motion.spindle-forward to this; I am at a loss how to do this though.

I really need help with this please guys as I've been stuck for a couple of days now with it.

EDIT
So I re-edited the 7i96 configuration via the tool and turned off the OUTPUTS which I had as spindle CW, CCW and ON functions mapped to them. This has let me load up LCNC.
I still have the issue that the manual control buttons do not show on AXIS.Does anyone know the correct HAL lines to add to make them show?
Also in the HAL file I don't have 'num_pwmgens=1' or an addf for pwmgen as asked for in the 2.8 documentation.
Does this matter?

You don't need the addf pwmgen as that creates a software PWMgen.
With correct firmware, the 7I96 will replace 1 or more step generators
with PWM generators, you can enable one PWM generator with
'num_pwmgens=1' though its not needed as the default is to enable
all modules (pwmgens, stepgens etc) if not specified
Once you have enabled the PWM generator you must setup its operating mode,
frequency and scaling and link the PWM generator pins to the corresponding
LinuxCNC spindle control pins.
This should have been done by the 7I96 setup utility
( so you might ask what's needed to setup the spindle in the 7I96 setup utility thread )
To do it by hand, You need to know the names and functions of the PWM generators
pins and parameters. You can get a list of the pin and parameter names
( and their current values ) by launching LinuxCNC and then in a separate
terminal typing this command:
halcmd show all *pwm*
The hostmot2 manual page describes the pin and parameter functions:
man hostmot2

That means you are not running a linuxCNC configuration with enabled pwmgen hardware

Shows the firmware loaded has PWM, the command in the terminal and linuxcnc running.
PWM is definitely loaded via the 7i96 configuration tool.

Sorry the command is
halcmd show all *pwmgen*
or
halcmd show all | grep pwm
I forgot that halcmd does not do a simple text match like vanilla grep
but seems to search only for complete tokens

That is a software PWM there, not hardware.
From the beginning:
What firmware do you have on your 7i96, what does readhmi report ?
You will most probably need to flash it with firmware that has hardware PWM, as noted by PCW.
After you flash it, reload and check readhmi again, it has to say PWM somewhere in it's output . Only after this continue setting up the config.

readhmid produces
This is using an old version of mesaflash hence the segmentation fault but I actually used the 7i96 configuration tool to flash it. When I use the same tool to read it there is no segmentation fault.

I flashed it via tool then reloaded and then started to set it up in the config tool.
Should this set up a manual PWM or is it a PWM only from the MDI commands?
Replied by jools on topic 7i96 Can't get PWM output
That is a software PWM there, not hardware.
From the beginning:
What firmware do you have on your 7i96, what does readhmi report ?
You will most probably need to flash it with firmware that has hardware PWM, as noted by PCW.
After you flash it, reload and check readhmi again, it has to say PWM somewhere in it's output . Only after this continue setting up the config.

Add the num_pwm = 1 to loadrt line for Mesa 7i76, or see if there is a provision for setting that in tool.
If not, after adding pwm to loadrt, there are some more lines to add to hal file that i do not know for sure, like scale, frequency and some other stuff that again i think PCW mentioned somewhere. There are 3 topics with this same problem so hard to keep track.
Another way of making this work is to create a config for 5i25 with hardware pwm and copy/paste the hal entries to your config, and just change the 5i25 to 7i96 in those lines.
