EDGE-CAN - CAN Frame configuration and output

We can provide fully functional CAN Bus messaging from the OEMV series of NovAtel's high performance GNSS receivers. Included with the new interface protocol is a PC based command interpreter, which enables CAN configuration on the MICROpod. Once configured the MICROpod will operate without intervention. The CAN interface will be provided for up to two OEMV receivers via 2 x CAN ports with data rates of up to 1Mbit per second and can be integrated with an IMU or as part of MICROpod-HDG.

The firmware provides additional functionality for the MICROpod unit to output customised CAN frames with NovAtel GNSS data through selected CAN ports. 

The MICROpod contains a GNSS receiver and provides a range of GNSS data through NovAtel messages. This data can be used to build specific CAN frames. The PC CANConfig Software provides a user interface for creating CAN frame configurations. It is used as a configuration utility for creating a list of CAN Frames that will be transmitted to the EDGE-CAN firmware. This utility allows practically any field from a standard NovAtel GNSS message to be selected as data used in a CAN Frame. The CAN ID’s are represented by a numerical value and are selected before editing. 

Once each CAN frame has been created the configuration settings are sent to the EDGE-CAN firmware via the maintenance port on the MICROpod. The EDGE-CAN firmware shall build and populate the CAN frames with the requested data and send the CAN frames through the selected CAN port at the selected rate.
