NMEA 2000 / CAN traffic (fuel flow sensor and GPS receiver)
-------------------------------------------------------------------------------
This is a set of example captures of the CAN / NMEA 2000 signals via an
SK Pang CAN bus breakout board (using a Microchip MCP2551 transceiver).
The data contains CAN / NMEA 2000 sample frames at 250kbps, the NMEA 2000
bus/network has the following equipment connected:
- Lowrance EP 60R (fuel flow sensor)
- Garmin GPS 17x NMEA 2000 (GPS receiver / antenna)
The signal grabbed is the (digital) CAN_RX pin of the MCP2551 chip.
