README.mdmicrocontroller-projects
A home for my microcontroller projects, including Stubby the Hexapod and others. It includes libraries for avr-gcc along with sample programs on how to use them, some KiCad modules, and the source code for a number of projects.
Some major projects include:
- Stubby the Hexapod (http://stubby.digitalcave.ca/stubby/) (Now extracted into its own repo at https://github.com/thebiguno/stubby)
- DrumMaster (http://drummaster.digitalcave.ca/drummaster/)
- Chiindii (http://chiindii.digitalcave.ca/chiindii/)
Some of the AVR libraries included here are:
- serial communications
- TWI (I2C), with support for master read / master write / slave read / slave write, plus callback functions for asyncronous communications
- reading data from a PS2 controller
- timer functions
- and much more

Questions
How big is the Chiindii PCB?
It measures 131.7 × 109.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chiindii use?
154 parts, built around the ATMEGA32U4-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Chiindii KiCad files?
From the thebiguno/microcontroller-projects repository on GitHub, at the commit this page was made from: the board is projects/chiindii/rev2.0/kicad/chiindii.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chiindii design in my own project?
Its repository states no licence, so its author keeps all rights: ask thebiguno before reusing the design.
