CAN-FIX is a CANBus based communication protocol designed for the exchange of flight data between aircraft systems. This project contains various utilities that can be used to monitor, configure, troubleshoot and update devices that implement this protocol. Right now the dependencies for this project are... Python 2.7 - I have not tried it with older (or newer versions) but it'll probably work with 2.6. pySerial - For serial port communication to CAN Bus communication adapters. PyQt4 - The program will revert to an interactive command line program if PyQt4 is not available but the functionality is limited. The only adapters which are known to work are the network adapter and the CAN-FIX-USB adapter which is the home grown Arduino based adapter that we made specifically for doing this kind of work. You can find details on it at... https://github.com/birkelbach/ArduinoCAN The EasySync adapter driver is close and could be made to work with minimal effort. The Data tab on the main screen will show the actual flight data that is currently seen on the network. The Network tab gives more detailed information about the state of the network. To monitor traffic on the bus make a connection to an adapter from the Comm menu, and select the Traffic tab on the main screen. The start/stop buttons start and stop traffic monitoring and the Raw checkbox is used to toggle between showing the raw CAN frame and the decoded CAN-FIX information. Firmware downloading is done but not tested. The current work is being done on the Network tree view and the ability to monitor and configure the network from this view.
