Pure Python implementation of the I2C SMBus protocol.

Project description

The pysmbus package is a pure Python reimplentation of the [python-smbus](http://www.lm-sensors.org/browser/i2c-tools/trunk/py-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.

Example

from smbus import SMBus

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