7i96s Flash for additional PWM and Wiring for laser

Hello PCW,
I flashed my 7i96s with 7i96s_2pwmd.bin and put this line to my custom.hal:

# invert pwm output
setp hm2_7i96s.0.pwmgen.01.out0.invert_output true.

When I start linuxcnc i get the error message
"parameter hm2_7i96s.0.pwmgen.01.out0.invert_output not found"

The hmid-output looks correct:
TB2 2,3 25 IOPort PWM 1 PWM (Out)
TB2 4.5 26 IOPort None

Did you enable 2 PWMGens in the hal file?

Hello PCW,
I managed to get rid of the error messages by changing these values in the hal file:
num-pwmgens = 2 (from 1) and
num-stepgens = 4 (from 5)

Now I also can see pwmgen.01 in the halcmd show all *pwmgen*:

roland@linuxCNC:~$ halcmd show all *pwmgen*

is this correct ?
Tahnks a lot and good night

Looks OK

You can also simply delete the num_xxxx=n stanzas in the hal file
and all hardware in a particular configuration will be enabled.
