CAN module

R2026b

On-board CAN controller module for XCP on CAN external mode communication

Since R2026b

Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / Groups / Host-board connection

Description

Select the on-board CAN controller module on the Arduino® hardware to use for XCP on CAN external mode communication. The available CAN modules depend on the selected Arduino board.

Note

XCP on CAN external mode is supported only on Arduino boards with on-board CAN controllers. Boards that use SPI-based CAN modules (such as MCP2515 shields) are not supported.

The selected CAN module determines which physical CAN pins on the Arduino board carry the XCP communication. When you change the CAN module, the CAN Bus Speed (kBit/s) parameter automatically updates to match the bus speed configured for that module in the onboard CAN properties.

The available CAN modules depend on the selected hardware board.
