PyBBIO update – version 0.9
PyBBIO finally has SPI support! It provides an Arduino-style API with some extra features, letting you use both the SPI0 and SPI1 modules. See the SPI documentation for more info.
A driver for the AM335x's built-in eQEP modules was recently added to the official BeagleBone Debian images, and PyBBIO now has a library that uses it to get input from up to 3 rotary encoders. See the RotaryEncoder documentation.
Just recently, SparkFun announced their IoT data logging service phant at data.sparkfun.com. PyBBIO now includes a PhantStream library, which is able to post data to and pull data from phant streams. Documentation here.
One of the first improvements Rekha made to PyBBIO was to move all file I/O based interfacing with kernel drivers to C extension. That means there is less latency when communicating with kernel drivers, which is a core part of all the IO functionality.
As of version 0.9, PyBBIO has dropped the Apache 2.0 license and is now released under the MIT license.
Among a host of minor bugs getting squashed, we found and fixed an issue where attachInterupt() was always causing an immediate false interrupt the first time it was called in a program.
