Hi,
i always get the following error when i try to run your example on my rpi2:
Error: I2CWrite(Io(Os { code: 121, kind: Other, message: "Remote I/O error" }))
What device are you using? Or do i need to do anything before running the example?
Greetings

Hi,
I'm currently using a RPI 1 Model B and and BME680 Pimoroni Breakout.
Could you send me a stack trace (run with RUST_BACKTRACE=1) ?
No nothing specific besides enabling the I2C bus as described in the RPI documentation.

Maybe your device path is different to mine(/dev/i2c-1)?

Yes the last part helped. I forgot to check if my i2c id is different -.-
The Watterott manual says:
TWI/I2C Interface (address 0x76 when SDO=0 or 0x77 when SDO=1, CS=1 for I2C)
Although i didn't connect anything to SDO it seems to get pulled up, so i needed to use 77 or connect it to ground.
Thank you very much :-)

Glad to hear that. Maybe I'll also turn the i2c address u8 into a proper documented enum. Sorry for the barely existing documentation, I'll fix that in the next release.
