Exellent service !!!
For CANduino v4 - ATmega328P with CAN-bus
My RAILUINO app required two modifications:
1. An extra (interrupt) wire between MCP2515 INT (pin12) and ATmega328P pin PD2 (pin32)
2. MCP2515 crystal should be 16MHz instead of 8 MHz.
The MassiveButDynamic was willing to to both modifcations. Incredible good service!!!
Now the CAN/ARDUINO works perfectly!!!
