Raspberry Pi

These are various scripts and programs that I have been making as I play with physical computing on my Raspberry Pi using its GPIO and the camera module. Most of these scripts are just demonstrations of basic functionality creating for my own edification, but maybe someone else will find them useful in their adventures.

cd4017be.py

cd4017be.py is a Python implementation of the CD4017BE counter/divider IC. I created it as a replacement for the physical CD4017BE that came with a Spinning LED Wheel Kit with which I've been playing. I've documented this script and the associated LED kit on my blog.

spi

This is a Python package that provides a simple software interface for SPI devices. I've also created some subclasses for specific SPI devices with which I've played; for example, poll_mcp3008.py is a script that uses the spi.MCP3008 class to get measurements from MCP3008 analog-digital converter chips.
