CAN Interface

The CAN Interface uses an SN65HVD230 (marked as VP230) CAN driver at IC18 on the MCBSTM32F200 board.

MCBSTM32F200 Board CAN Interface

The CAN DB9 connectors are wired so that Pin 2 provides the CANL signal and Pin 7 provides the CANH signal. These pins are connected to a SN65HVD230 CAN driver. The jumpers at J15 allow you to configure the CAN driver IC to the CAN1 or CAN2 interface on the MCU.

Jumper J16 incorporates a 120 ohm termination resistor between the CANL and CANH signals.

Note

  • CAN termination resistors make it easy to connect the MCBSTM32F200 board to your CAN network but they are not always required. When connecting the MCBSTM32F200 Board to a CAN network, you may need to remove jumper J16.
