Arduino MKR Zero & MKR Can Shield -> SREG not defined, cli(), sei() about nmea2000_mcp HOT 5 OPEN

I still like Teensy more...

The changes should be OK with quick look. I should add defines for NMEA2000_mcp.cpp - others has also used mcp_can on different environment.

Do you use mcp_can library from my git? I am not sure of status from other sources and mine can also handle both transmit and receive with interrupt. You could also try to leave int pin undefined, so it should use just polling, which is enough on the tests.

I have not heard others using MKR.

I have to use the MKR Zero, because I do not built the electronics from scratch, I just add NMEA2000 functionality to an already existing project...
Yes I use your mcp_can library.
I will try leaving the int pin undefined in the evening.

Is this issue solved? I want to use the Arduino MKR WIFI 1010 and the MKR CAN shield.
My current solution works with MEGA and CAN shield from Seed, but i want to chnage to smaller Hardware.

Or can i use the teensy 3.6. I read that the Teensy 3.6 has CAN onb board. Is this with Transceiver and Controller?

from nmea2000_mcp.

Should be. I have modified NMEA2000_mcp to use SREG only with Mega and Uno.

All Teensy 3.2 and up has internal can controller and requires tranceiver ship. I have used MCP2562 without any problem. With ISO1050 tranceiver you can make isolated system.

As a feedback to @ttlappalainen, and to those that find this tread in the future:
I have with success, used a Arduino MKR Wi-Fi 1010 and the MKR CAN shield on a NMEA2000 network, using ttlappalainen's NMEA2000 library and a Raymarine axiom 7 as MFD

I have 3 ds18b20 (one-wire Temperatur sensor) connected on a one-wire bus, then senses temperatures on my old VP 2003t engine.

For testting purpose, the alarm is set to 26 C, in case you wondered..;)

I can highly recommend ttlappalainen's excellent document "Connecting_hardware_to_NMEA2000.pdf", specially the troubleshooting section :
