Issue with Attaching BME280 Sensor to Raspberry Pi 4B on LinuxCNC

Hello #MyFirstPostHere,I am trying to attach a BME280 sensor to a Raspberry Pi 4B to monitor environmental variables (temperature, pressure, and humidity). The sensor is connected to the 3.3V, GND, GPIO2, and GPIO3 pins. It works flawlessly when running Raspbian OS (64-bit), and I can retrieve readings via the terminal.However, when trying to use it with LinuxCNC, I encountered multiple errors.Upon checking the I2C buses with the command , I found and , but I was expecting , as seen in Raspbian OS.I was wondering if there is a solution for this? Is it possible to get this sensor working on LinuxCNC?Please feel free to ask for any additional information.

No idea if there is a driver for I2C in LinuxCNC, maybe searching on github project page would show if there is anything about it there.

probably possible, here are a few rpi/ i2c driver samples i have saved

Thank you cakeslob for the response,

I was checking in Linuxcnc system, and the observation was there is no /dev/i2c-1 even if i create it couldn't be read and shows "no such devices or address".

Is it possible to get it ?

What are all the process ?

What am i doing wrong ?
