The Hamster man, Mike Field has a new project up that is an intelligent I2C controller. It is a small programmable controller that makes it quick and easy to talk to I2C devices. The controller has a single I2C bus, 16 binary inputs, 16 binary outputs and writes I2C data to 32 8-bit registers.
The project is up over at Mike’s site Hamsterworks (there are a wealth of other Papilio-related projects and tutorials at the site too, if you’ve never checked it out). Let’s look at a quick overview, as excerpted from Mike’s project page:
On the Hamsterworks project page, there’s a great example using the I2C Intelligent Controller to read data from a 3d compass sensor, complete with code.
