Python tools for electrical busses
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]
$ python Python 2.7.10 (default, Dec 3 2015, 13:28:10) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.1.76)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import bustools.platforms.totalphase.tp240310 as tp240310 >>> import bustools.adapters.aardvark as aardvark >>> aardvark.print_devices() # find Aardvark devices attached to this system 1 device(s) found: port = 0 (avail) (2237-889465) >>> 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()
