CAN bus speed

R2026b

CAN bus speed for host-side communication during XCP on CAN external mode

Since R2026b

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

Description

This read-only parameter specifies the baud rate for the host-side CAN hardware during XCP on CAN external mode communication. This value must match the baud rate configured on the host CAN interface to establish communication.

Dependencies

To enable this parameter:

1. Set Hardware board to one of these boards:

   • Arduino® Due

   • Arduino Uno R4 Wi-Fi®

   • Arduino Uno R4 Minima

   • Arduino Nano R4

   • Teensy 4.0 (Arduino compatible)

   • Teensy 4.1 (Arduino compatible)

2. Set Communication interface to XCP on CAN.

3. Set Host interface to Simulink.

   This parameter automatically synchronizes with the CAN Bus Speed (kBits/s) of the selected on-board CAN module. When you change the CAN module or update the bus speed in the onboard CAN module properties, this parameter updates automatically to maintain consistency.

Settings

synced from on-board CAN module bus speed (default)

The value is displayed in kbit/s and is read from the on-board CAN module configuration. Supported bus speeds depend on the selected hardware board and CAN module.

Common bus speed values: 5, 10, 20, 40, 50, 80, 125, 200, 250, 500, 1000 kbit/s.
