HAL Driver for Raspberry PI GPIOs

Hi,

I am new to this, but i badly need to make Linux cnc to work with RPI GPIO outputs. Maybe someone could share like a working example of configs?
Or maybe someone please explain step by step how to do it.

Thanks in advance.

This is from my wooden mill ... enjoy

Thanks very much !

I get error hal_gpio: dlopen: /usr/lib/linuxcnc/modules/hal_gpio.so cannot open shared object file.

In directory there is only closest to it hal_bb_gpio.so...

Maybe i could get that file too please?

oh, sorry, please use "hal_pi_gpio" and you'll need linuxcnc 2.8, the gpio driver for rpi is included in linuxcnc since some months now.

Thanks again !

Wouldnt managed myself to do so much. You are a savior . Changed to hal_pi_gpio. Seems like everything works, getting some weird end stop errors, but from this point everything is manageable.

Anyways, i will analyze, and actually i have a task of doing SCARA robot control using LinuxCNC via RPI GPIO. Now feeling quite comfortable.

Oh, I had erratic endstop triggering, too. I used software debouncing and they were gone. Here is the hal-file with debouncing - sorry, the last config was an old backup. Please test:
