7c80 install on rpi 4

Spindle analog is controlled by PWMgen 0
The isolated outputs are SSRs (same hal names as 7I96)
Spindle ENA/FWD is GPIO20, Spindle DIR/REV is GPIO21
Both active low.

halcmd show pin hm2 will show all the hardware pins
halcmd show param hm2 will show all the hardware parameters

Thanks for the quick replay - I will check and post later as I have some other task open from my day job

Sir:
Sorry for the delay, I saw the post, wasn't convenient to deal with it right then, then forgot later

Attached are my HAL and ini files.  The ini file is specific to my hardware, but may give you something useful to work with.  The hal file is what I am using to run my machine.  At the moment I don't have a controlable spindle, but the movement works well.

I do have two parallel steppers running the y axis, so you may need to adjust that bit.

If you have questions I will try to take note and monitor this thread for a few days.

This should be close to a working spindle section of a 7C80 hal file:

Hi there   !!!

Thanks a lot for the many valuable replays and finally after some days of testing my machine is homing !!!!!
Well, I need now to make sure the spindle runs and the E-Stops working etc..
I still would need some hint in regards to the outputs

# --- MACHINE-IS-ENABLED ---
net machine-is-enabled  =>   hm2_7c80.0.led.CR01 => hm2_7c80.0.gpio.012.out

This one is switching the LED and in HAL-Monitor as well the output but physically I don't have anything in Output 0

... or I just lost myself ?

Thanks for some hints!
 

The outputs on the 7C80 are SSRs:

net machine-is-enabled => hm2_7c80.0.ssr.00.out-00

gpio12 is a sserial expansion port on a 7C80
Do not set it to output mode or you will create a bus
