micropython-smbus

A wrapper to provide methods of the CPython 'smbus' module on micropython

Provides an 'SMBus' module which supports some of the py-smbus i2c methods, as well as being a subclass of machine.I2C

Hopefully this will allow you to run code that was targeted at py-smbus, unmodified on micropython.

Usage

Use it like you would the machine.I2C class:

        import usmbus.SMBus 
        bus = SMBus(SMBus.MASTER, pins=('G15','G10'), baudrate=100000)
        
        # Example for the bme680:
        bme680.BME680(i2c_device=bus)

Work In Progress

This module came from a desire to use https://github.com/pimoroni/bme680 on a LoPy, so currently implements only the methods necessary to do that.

I'll be adding more as time goes on: issues/pull requests are very welcome.
