The Komodo GUI Software provides access to the CAN functions of the Komodo CAN DUO Interface in an easy-to-use graphical interface. The Komodo GUI Software has two operating modes -- Activity Board mode and General CAN mode. In Activity Board mode, the software polls the CAN devices on the CAN/I2C Activity Board Pro and provides graphical updates in real time. In General CAN mode, the software monitors a CAN bus and displays CAN packets, events, and errors in the transaction log as they occur. In the latest version of the software, it is now possible to send arbitrary CAN messages onto the CAN bus as well.
