Hi all,

I’m working with @cshill at the University of Minnesota Duluth on integrating multiple i2c water quality sensors with the bristlemouth. I was wondering if there is anything developed for i2c (similar to the payload\_uart files), or if anyone has had success doing anything of the like.

Thanks!

Hi Henry! Welcome to the community!

Yes, there are plenty of examples of i2c! The `devkit_monitor` app uses i2c to collect power monitor, humidity and temperature data from the devkit’s on board sensors. These sensors and several others are using the `AbstractI2C` class defined in `abstract_i2c.h`. The drivers for these sensors, located in `bm_protocol/src/lib/drivers/`, have good examples on how to use the `AbstractI2C` class. A couple good examples are the ina232 driver (the power monitor) and the TCA9546A driver (an I2C mux).

Best,  
Victor
