Executive Summary

Picture that summarizes the project.

BBIO are a group of library files for GPIOD that are written in C that uses Python wrappers to run it in Python. Our project is to rewrite the Python to be fully in Python rather than using wrappers.

What works: The GPIO, UART, and ADC capabilities will now run the same way they normally would except the Python does not use a Python wrapper.

What isn't working. The programs have only been tested on the BeagleBone Black with kernel 4.19. The BBIO programs may not function correctly on other kernels or BeagleBones.

Conclusion: The BBIO library no longer requires a Python wrapper as all of the functions interact with the BeagleBone directly from Python.


If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions

Give step by step instructions on how to install your project.

  • Include your github path as a link like this to the read-only git site:
  • Be sure your is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
  • Include a Makefile for your code if using C.
  • Include any additional packages installed via apt. Include and files.
  • Include kernel mods.
  • If there is extra hardware needed, include links to where it can be obtained.

User Instructions

Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.

Consider making it autostart for full credit.


Here is where you brag about what your project can do.

Include a YouTube demo the audio description.

Theory of Operation

Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown

Joshua Key and Eric Morse did pair-programming.

We worked the entire project and all modules together.

We completed all GPIO functionality of GPIOD, including event detection.

We completed all UART functionality of GPIOD.

We also completed all PinMux and ADC (Analog to Digital Conversion) of GPIOD.

Future Work

The columns are being changed in an update to BBIO, which will mean that the columns of our table will need to be changed to reflect that. The code should work fine, but maintenance of the code will need to happen if it does not work under any new update.


Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
