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 Preamp PCB?
It measures 15.2 × 10.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Preamp use?
18 parts, built around the J111. 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 Preamp KiCad files?
From the thebiguno/microcontroller-projects repository on GitHub, at the commit this page was made from: the board is projects/preamp/preamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Preamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask thebiguno before reusing the design.
