Python tools for electrical busses

Project Description

Python tools for electrical busses such as I2C and SPI.


This package is very much a work in progress, and there is no real documentation yet… There is currently basic support for the Total Phase Aardvark adapter as an I2C master. There is also initial support for a couple I2C slave devices (see bustools/devices/) and the I2C/SPI Activity Board platform.

The public API is not guaranteed to be stable until 1.x release.


The bustools package can be installed from PyPI using pip:

$ pip install bustools

Support for the Total Phase Aardvark adapter is not included by default since it only supports Windows, Mac OS X, and Linux. To include support for the Aardvark adapter, you need to specify the ‘aardvark’ extra:

$ pip install bustools[aardvark]




The following example uses the Total Phase Aardvark adapter to turn on LED D0 on the I2C/SPI Activity Board.

>>> with aardvark.Aardvark(0) as adapter:
...     adapter.target_power = True # enable power to the activity board
...     activity_board = tp240310.TP240310(i2c_master=adapter)
...     led = activity_board.d0
...     led.on()
