Created the example for this library, there are drawbacks though. This version of the library does not allow the sketch to see if a received CAN message is standard or extended in length, I suggest using the sub-development branch if you are serious about bridging. UNTESTED! I HAVE NOT TESTED THIS
Excel document that helps determine the configuration register values.
Made serial output more useful as a CAN sniffing tool and to demonstrate using the extra bits of the ID.
Mega2560 bootloaders and can cause timeouts during upload
Triple bang is a special command for the Mega2560 boot loader.
There was an extra sendMsg() in one of the sendMsgBuf() functions.
Loop back example to test a single CAN interface.
…N_loopback.ino ...
Update Dual_CAN.ino
Static emulation of OBD ECM responses.
Missing example copied from forum post https://forum.arduino.cc/index.php?topic=402018.msg3209207#msg3209207
Improved sleep functionality
Guard DEBUG_MODE to allow control from the main program.
Fixed small spelling mistakes.
Allow clkout to be selected in CNF3 register.
Manual spelling fixes.
Guard debug mode definition
The Send timeout was based on an incrementing register and a while loop that ran at system execution speeds with no delays. I have changed it over to use the Arduino micros() function.

Maintain the deterministic timeout for sendMsg().
Fixed typo...
SPI-Bus selectable in constructor
Fixes errors in example.
Fixing issues caused by #27
Fixing issues caused by #27
- fix setMsg to respect the len - try to prevent buffer overflows and always limit to MAX_CHAR_IN_MESSAGE
fix setMsg and clearMsg
This update introduces configurations for the MCP_CAN library to support a 10MHz crystal oscillator. The following baud rates have been tested and verified with a MIKROE-986 CAN SPI Click 3.3V on an Arduino Nano 33 IoT, in communication with a CANBED v1 from Longan Labs: - 125 kbps, - 250 kbps - 500 kbps - 1000 kbps
Added 10MHz crystal support
