ArduinoIO HAL component

Do you want LinuxCNC exit by a component?

I would like that if the component fails LinuxCNC stop, inform the user and exit because I wanna connect ArduinoIO for drive the changing tool hardware .
How can i do it?

I wouldn't recommend to terminate LinuxCNC in that case. Because that will also kill your notification and it's worst if the program just terminates and you don't know why.

I would connect a pin of your component with some logic to iocontrol.0.emc-enable-in to stop LinuxCNC.
Before that you can create a message with linuxcnc.org/docs/html/man/man9/message.9.html

Yes I can use a workaround but in the log files I can read the reason of LinuxCNC exit so this is not a problem, I think that for security reason if a module fails the control have to stop.

Thanks Dino, it will be useful for me to read the dc spindle current and pass it to linuxcnc
thanks again

Hi, i am having a problem getting Linuxcnc to load with ArduinoIO.
It says - execv (arduinoIO): Permission denied.
I attached the Bug report.
I tried adding permission to the .rules file but no luck.
any help would be greatly appreciated.
Thanks
