Using Raspberry Pi GPIO header pins from RatOS/Klipper
I was just happily configuring an additional chamber temperature sensor (https://www.klipper3d.org/Config_Reference.html?h=temperature+sens#ds18b20-temperature-sensor). The DS18B20 has a one wire interface, which i'd like to connect to the Raspberry Pi that also runs my RatOS.
After checking that i get reasonable readings from the sensor via cli&ssh i tried to implement the sensor in my printer.cfg. I struggled when i needed to name the "sensor_mcu" name (which in my case is the Raspberry Pi), because i could not find the name of the Raspberry Pi mcu in the RatOS docs.
- Is RatOS implementing the host mcu (Raspberry Pi) as secondary mcu per default?
- If yes: How can i refer to the RPi mcu in my klipper cfgs?
- If no: When i install the RPi as mcu (https://www.klipper3d.org/RPi_microcontroller.html), will i break my RatOS installation, or make it not updateable? Is there a "RatOS-Way" of implementing the RPi as secondary mcu (compared to the toolboards - which is great btw.!) ?
Thank you so much!
