The piio project aims to provide a library for accessing the I/O capabilities of the Raspberry Pi from Tcl.

The piio package supports three of the I/O methods available on the Raspberry Pi via three new commands:

* [piio](wiki?name=piio) for general purpose I/O, also known as gpio.
* [twowire](wiki?name=twowire) for Inter-Integrated Circuit, also known as i2c.
* [spi](wiki?name=spi) for Serial Peripheral Interface bus.

In addition it makes a number of modules available that support specific i2c devices:

* [dallas](wiki?name=dallas) for a DS1621 temperature sensor
* [jeebmp](wiki?name=jeebmp) for a BMP085 pressure (and temperature) sensor
* [jeeio](wiki?name=jeeio) for a MCP23008 8 pin I/O chip
* [jeelux](wiki?name=jeelux) for a TSL2561 light sensor
* [onewire](wiki?name=onewire) for a DS2482 1-wire interface driver
