Features

• Democratic network - no single point of failure.
• Publish/subscribe or request/response exchange semantics.
• Allows efficient exchange of large data structures.
• Lightweight, easy to implement protocol.
• Supports network-wide time synchronization with microsecond precision.
• Doubly- or triply- redundant CAN bus.
• Can be used in deeply embedded, resource constrained, hard real-time systems.
• The specification and high quality reference implementations are open and free to use.

	UAV Gui Tool Hangs on Anonymous Node Ok. By now you all know that I am still figuring all this out. So please bear with me. I was able to use an Arduino Uno and a CAN-Shield as a CAN-USB interface to the PC using: https://github.com/latonita/arduino-canbus-monitor. Working on getting it over to a Teensy. But that's I stray… 2018 Aug 13 by CyberMerln
	Subscribing to vendor specific messages Hi all I managed to turn libuavcan into Arduino style library for use with the Teensy 3.x mcus. The teensy driver and examples are taken from the UAVcan site and tum-phoenix (https://github.com/tum-phoenix/drive_teensy_main and https://github.com/tum-phoenix/drive_teensy_libuavcan) and modified… 2018 Aug 09 by CyberMerln
	Any plans on developing more powerful motor controllers with position sensor support? Hi! Orel and Myxa are great products. Especially due to support of UAVCAN. Any plans on developing more powerful stuff with support for position sensors (Hall sensors at least) and with torque control mode? I would like to see those integrated in solutions like unicycle. Which requires voltages up t… 2018 Jul 23 by a6a3uh Category General

I have read tht I need to put this code on the mem card to get the baro working, but I see it uses the command “fi” is that a spelling mistake and it should read “If”. # uORB will be started again by the main init script later, it's OK if uor… 2018 Jun 21 by Richard_Gardner Category UAVCAN
	GNSS GPS on Pixracer Hey guys. Last night I installed my GNSS v2 GPS. It’s all powered and connected to the Pixracer. I have a termination plug in the second port so I figure I should be good. I set the GPS type to 9 and rebooted. NO GPS. So then I read that if there is a redundant port it needs termination as w… 2018 Jun 20 by Richard_Gardner Category UAVCAN
	Proposed Changes to UAVCAN's High-Level Architecture I'd like to propose some changes to the high-level architecture for UAVCAN to make it more modular and allow for different types of UAVs to utilize it. The modifications will introduce the following new concepts: - *Specification Levels* – Pre-defined integration points to define and… 2018 Jun 19 by Scott Dixon
