NMEA2000_mcp library for Arduino

Inherited object for use NMEA2000 library for Arduino Boards with MCP2515 CAN bus controller. See also NMEA2000 library.

To use this library, you will also need NMEA2000 library and developed version of mcp_can library, which you can download from https://github.com/ttlappalainen/CAN_BUS_Shield until changes has been implemented to original https://github.com/Seeed-Studio/CAN_BUS_Shield library.

Changes

27.03.2020 Added ICACHE_RAM_ATTR to Can1Interrupt by TyphoonSB.

18.07.2019 !Critical fix for interrupt receive. If receive buffer got full, interrupt started to loop and system hanged. After fix if buffer gets full, incoming frames will be ignored, but system does not hang.

04.10.2018 Get rid of min(…​) for better compatibility.

12.09.2017 Improved ISR speed 50% by improving mcp_can.

08.09.2017 Fix for sending. Both receiving and sending will be handled by interrupt. Requires improved mcp_can.

02.02.2016 Fix for sending. Interrupt has to be disabled during send, if interrupt is in use.

23.01.2016 Interrupt support for receiving.
