I use Vector network to send CAN messages to MCP2515 through CAN HIGH and CAN LOW lines. I connect MCP2515 with Arduino Due through SPI protocol.

Connections are good. But I receive "not acknowledge error" in the CANoe software.

I can't send CAN message to the MCP2515 itself.

  • please provide schematic or connection diagram .... also provide the minimum code that exhibits the described failure – jsotola Jan 8 at 18:30
