This is disappointing news. I have been working on a follow-on to the K9 Smorgasboard and had assumed that I2C devices would be easy to support. Both the original Smorgasboard and the new board that I am working on use the Beaglebone Black I2C2 bus to interface multiple devices. Leave it to a hardware guy to assume that the software would be simple. 8-( Steve Stallings PMDX ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
