7i47s Analog out

Can someone give me an example for the analog out of the 7i47s, regarding for spindle control?
Is that a hardware PWM or need as software PWM? The Bit file is correct, I got it direct from Mesa. thx!
I tried a lot bus nothing works. Using l-cnc 2.9.
Any suggestions are welcome!

You would use hardware PWM set to about 5KHz
What bit file are you using?

attached the bit file and pin file.

for hardware pwm I should see these pins in HAL-Show, right? But there is only pwmgen.value and pwmgen.on.

How does the hardware PWM would look like in HAL?

pins should it should be something like

hm2_5i24.0.pwmgen.00.enable
and
hm2_5i24.0.pwmgen.00.value

and parameters
hm2_5i24.0.pwmgen.pwm_frequency
etc

ok thank you, I got it, so far so good:

for testing I´ve this in the hal:
setp hm2_5i24.0.pwmgen.00.scale -100
setp hm2_5i24.0.pwmgen.00.output-type 1
setp hm2_5i24.0.pwmgen.00.enable TRUE
setp hm2_5i24.0.pwmgen.pwm_frequency 5000
setp hm2_5i24.0.pwmgen.00.offset-mode 0
setp hm2_5i24.0.pwmgen.00.value 20

But
if the value is 20 the voltage is 8V
if the value is 80 the voltage is 2V
but I guess it should be vice versa?

yes, that was a try to revers the behavior but it is the same if the scale is +

From the 7I78 manual:

"Spindle PWM is active low so if the 7I78 is used with HostMot2 firmware, the PWM output must be inverted."

on a 5I24 (and LinuxCNC 2.8 and above) you would:

setp hm2_5i24.0.pwmgen.00.out0.invert_output true

ok, now I´ve it almost !

here the HAL:
setp hm2_5i24.0.pwmgen.pwm_frequency [SPINDLE_0]PWM_FREQ
setp hm2_5i24.0.pwmgen.00.scale [SPINDLE_0]OUTPUT_SCALE
setp hm2_5i24.0.pwmgen.00.output-type 1
setp hm2_5i24.0.pwmgen.00.offset-mode 0 # 1 wenn value +- dann bei 0 = 50%
setp hm2_5i24.0.pwmgen.00.out0.invert_output true # damit der PWM Ausgang bei steigendem Value auch ansteigt
setp hm2_5i24.0.gpio.016.is_output 1 # gpio 016 ist Aux (M4) - auf Ausgang setzen
setp hm2_5i24.0.gpio.016.invert_output 1

net spindle-speed-cmd spindle.0.speed-out-abs => hm2_5i24.0.pwmgen.00.value
net spindle-on spindle.0.on => hm2_5i24.0.pwmgen.00.enable # FU und PWM enable
net spindle-fwd => spindle.0.forward => hm2_5i24.0.gpio.016.out # gpio 016 / Aux (M3)
net spindle-rev => spindle.0.reverse => hm2_5i24.0.7i90.0.0.p1-out-02 # M4 - da DIR nicht ansprechbar -> 7i90

Then I figured out that the markings for the optocoupler outs on the 7i47s (EN, DIR, AUX) are vice versa, + is - and - is +. But that does no matter for me.

The only thing I can´t figure out how to set the DIR output? Probably gpio.017 is for that purpose, but the only opportunity is to set the Parameter setp hm2_5i24.0.pwmgen.00.out1.invert_output to 0 to get a state change. This is not a pin so not possible to connect with 'net'. A out-pin related to gpio.017 I couldn´t find.

Depending on firmware, DIR will be controlled by the sign of the PWM rather than a GPIO bit

What is reversed about the Optocoupler outputs?
