Description

microME

My attempt at building a powerful microcontroller-based home computer.

All its features are software-defined, at its core there's a Teensy 3.5 providing the video output. Keyboard and basic I/O is handled by an Arduino Nano. Extended sound and music can be handled by a Teensy 3.2. The microcontrollers are connected via serial, and interrupt lines going from the I/O or sound controller to the main controller.

There are multiple connectors available for extensions. (Work in progress)

Everything else is controlled by the software running on the controllers.

And, the computer is also your development platform, just connect the controller via usb directly.

The software repo for this project can be found here: https://github.com/dherrendoerfer/microme

This YouTube playlist is part of the documentation effort of building this little thing: https://www.youtube.com/playlist?list=PLotvT33qzzfLngX3hz38-cLI_gx5IjP4y
