6.0. CAN module
CAN (Controller Area Network) is a communication standard primarily intended for use in automotive industry. It
enables the microcontroller to communicate to a device installed in cars without using a host PC. In addition, this
communication is widely used in industrial automation. The
EasyARM v6
development system features CAN module
used for communication with CAN devices. To establish connection between this module and the microcontroller, it is
necessary to set switches 1 and 2 (optionally 3 and 4) on the DIP switch SW3 to the ON position.
