BeagleBone driving LED Bar via I2C

I've just posted a video of the BeagleBone driving a bar LED via I2C. The Bone is programmed in Python, and I'll shortly be checking the (open source) code in at Quick2Wire's github repository.


Expect to see a Raspberry Pi performing the same trick as soon as we can get our hands on one!

I hit a couple of snags while getting this going. Fortunately the inexpensive OpenWorkbench Logic Sniffer makes it really easy to debug I2C and SPI applications.
