Blog Has Moved!

I have moved my blog over to the Wordpress platform at http://offkilterengineering.com/blog.

Blogger has been great but it is nicer to consolidate all my content into one place.

BeagleBone Dynamixel AX12 Interface - Part 2

 

I have made some progress interfacing the Dynamixel AX-12 servo with the Beaglebone.

In this video I have breadboarded a sparkfun logic level converter to convert the Beaglebone's 3.3v UART logic to the Dynamixel's 5v logic and a Tri state bus buffer to convert the Beaglebone's UART signals to half duplex.

I have run into one snag however...
It seems that the Beaglebone's UART are only able to properly work up to 115.2k baudrate by default. If anyone knows how to adjust the maximum baudrate of the Beaglebone's UART to 1M or even 3M baud please comment!
