Pure Python implementation of the I2C SMBus protocol.

Project Description

The pysmbus package is a pure Python reimplentation of the [python-smbus]( package. This allows using the I2C SMBus protocol without having to compile C.

It has the same module name, smbus, as python-smbus, so that it can be used as a direct replacement in projects that normally depend on python-smbus.

Currently it’s incomplete. The following methods are implemented:

  • write_byte_data
  • read_byte_data

Other methods haven’t been implemented yet, since I don’t have any hardware needing those methods. Patches or requests for other methods are welcome.

This package has been comfirmed working with Python 2.7 and 3.4.


from smbus import SMBus

bus = SMBus(1) # Opens /dev/i2c-1 bus.write_byte_data(0x54, 0x13, 0xff)
