Beagleboard and Atmega8 Communication

[spizzak]

Hi all, I'm working on a project where a BeagleBoard needs to communicate with my Atmega8 which is doing servo control. Can someone suggest what the best interface or method for this would be?

Thanks

You will probably want to use a level shifter since the most of the IO on the BeagleBoard is a 1.8V device.  You can use a level shifter.  For an idea, look at the schematic linked on this page for the tincan trainer board for a sample of Atmega328 interfacing to the BeagleBoard.  Maybe it is worth the investment in that trainer board if you want to do other interfacing to the BeagleBoard.
