CAN bus of ECI1000 uses internal power.
When multi controllers are linked on CAN bus, it is necessary to connect 120 Ω
resistor between CANL and CANH of the last IO expansion module.
For CAN bus communication, when using different powers, GND of controller
and GND of expansion module should be connected together. When the controller and
expansion module use different powers, controller power GND should be linked with
expansion module power GND, or CAN will be burned.
