SN65HVD230 CAN Bus Transceivers #107

Closed melucas closed 6 years ago

Hello,

Found these CAN bus transceivers on eBay (SN65HVD230). Will they work with this NMEA200 library?

Thanks, Michael

Library does not see tranceivers. Only CAN controller matters. As you can read from documents currently supported contollers are Arduino DUE, ESP32, Teensy 3.2-2.6, MCP2515. Tranceiver makes a physical connetion from controller to bus. With quick look I did no saw reason why that would not work with CAN bus - that what it is for. Just take care that your controllers is 3.3 V.

Will a Mega board work? I have a sparkfun CAN-BUS shield (DEV-13262) which has a MCP2515 chip to connect to the Mega. The Mega is a 2560 R3.

Started testing with a DUE. I'm trying to get the Getting Started section, I'm trying to get the TemperatureMonitor to run.

I have the sparkfun CAN-BUS shield (DEV-13262) connected to my Due. I'm still waiting for the transceiver shield which uses the internal CAN bus.

I'm seeing the following error:

PGN 130310 send failed 37725 : Pri:5 PGN:130310 Source:22 Dest:255 Len:8 Data:1,C1,70,FF,FF,FF,FF,FF

How do I debug the sending to find out what the send issue is?

Thanks, Michael

Is it possible to tell the NMEA 200 library which SDA and SCL pins to use? The Due and CAN-BUS shield are connected to SDA1 and SCL1.

Dumped the CAN-BUS shield and a connection to my Raymarine SeaTalkNG network working with the CJMCU-230 Can Bus Transceiver:

You can close this issue.
