CAN
communication
Controller Area Network (CAN or CAN
bus) is a vehicle bus standard designed
to allow microcontrollers and devices to
communicate with each other within a
vehicle without a host computer. CAN
is a message-based protocol, designed
specifically for automotive applications
but now also used in other areas such
as industrial automation and medical
equipment. EasyMx PRO
is equipped with SN65HVD230 – a 3.3V
CAN Transceiver and a pair of screw
terminals which provide microcontrollers
with integrated CAN controller with
the necessary physical interface for
CAN communication. Make sure to
correctly connect negative and positive
differential communication lines before
using this module.

In order to enable CAN communi
cation, you must push SW10.5
(PD1) and SW10.6 (PD0) to
ON position. This connects the
TX and RX lines to appropriate
microcontroller pins.
