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!

MWScore New Features

Spending the last few days before RoboGames 2012 getting the Mech Warfare MWScore Scoring Server software into shape.

An exciting new feature I have added is the ability for match data to be broadcast to other computers on the same network as the scoring server PC.

 

Source for everything related to the MWScore system (PC server software, transponder firmware and transponder board designes) can be found on my MWScore project page.
