Making AVRCam a slave I2C

Postby Guy Ziv » Thu Aug 17, 2006 7:22 am

I have a microcontroller that can act only as a Master I2C. I want to make a version of the AVRCam software that can send information e.g. tracking information in response to the microcontroller I2C commands. Is it possible to make the AVRCam dual Master/Slave, or otherwise add a "bit banged" I2C slave port on the AVRCam?

You may want to check out the following link: ... cam_Design

These guys have taken the AVRcam, migrated it to a beefier AVR micro (mega64), and added some additional features (one of which is support for I2C interfacing, if I recall). They have all of their software changes released under the GPL, so you can poke around and see what they have.
