PICAN-M, no NMEA 2000 traffic

[ryanathompson]

Really struggling with this...  I have a PICAN-M on a RPi 4 running OpenPlotter with everything up to date.  I have a four port Nmea 2000 backbone:
1. Port 1:  Power, (verified that ~13v running through the N2K network)
2. Port 2:  PICAN-M+RPi
3. Port 3:  Garmin GPS 19x NMEA 2000 antenna
4. Port 4:  CX5003 NMEA 2000 sensor unit with voltage being monitored
5. Terminators at both ends, no open ports.

I've followed and refollowed the PICAN-M setup and everything is configured.  

The Problem:  No traffic on a CANDUMP.  I see nothing, just a blank screen.

The PICAN-M manufacturer said that as long as there isn't an error on the CANDUMP, THEIR unit is working.  

This is a test setup so I don't have another device (like an MFD) to test N2K.  

Any ideas?

Ignore the PICAN-M setup because it is obsolete. Follow the openplotter setup in a fresh openplotter v3 image: https://openplotter.readthedocs.io/en/3....p2515.html

Did all this and verified SPI0 CE0, Osc 16000000, Int GPIO 25.  

Nothing on the CANDUMP

Solved this.  Brand new terminators bought on Amazon were bad.  No ohms change when they were on the network.  So frustrating.  Buy name brand!

you forgot to add the signalk connection in your topmost openplotter can interface.

Yep, done now that I have a good candump. Thank you.
