CAN communication by using the microcontroller

This section describes how to perform practical CAN communication with the microcontroller.

On the board, as shown in “Figure 5-7 CAN circuit”, the microcontroller is connected with the CAN

transceiver (MAX3058). TX0 on the microcontroller is used for transmission and RX0 is used for

reception. Signals transmitted/received are transferred to CAN-High and CAN-Low as the differential

signals on the bus through the CAN transceiver.
