1 Wire Sensors on Portenta Machine Control

Official Hardware Pro Solutions Portenta Machine Control

Hi,

I am using the GitHub - arduino-libraries/Arduino_MachineControl library and I want to connect additional 1 Wire sensors to the Portenta Machine Control board as I would like to use the board as some kind of MQTT IO Slave for my home control. I was wondering which PINs I could use for that, as I would need a direct GPIO pin for the OneWire.h libray?

Or is it a better way to use 1 wire sensors over an I2C 1 Wire Master on that board?

Thank you in advance.

Hi Bernhard,

Your best bet would be to go down the I2C route as the PMC does not support 1Wire to my knowledge. I did try this myself but ended up abandoning efforts and switching sensors.

I hope this helps a little.
