# Opening a CAN Node

TYPE | DIRECTIVE | OPTIONAL | ARGUMENTS
Operation | canopen | No | <can_node_value> <cris_value>

The canopen directive is used to open a CAN node.

Example of use :

> batchisp -device t89c51cc01 -hardware PEAK -operation canopen 0xFF 0x01 erase F canclose 0xFF

Any CAN node should accept the 0xFF value and toggle to ISP mode when it receives the canopen command.

If the CAN device is the only one connected to the PC, you may keep the default 0xFF value. If you want to perform ISP on a particular CAN node in a CAN network, you must specify the CAN node value of the target node.

The CRIS (CAN Relocatable Identifier Segment) value is used to setup the CAN dongle acceptance filter. If you omit this argument, the CRIS default value is zero.

Warning : You should always use the canclose directive before ending a CAN batchisp session.
