CAN (Controller Area Network) is a communication standard primarily intended for use in automotive industry. It enables the
microcontroller to communicate to a car device without using a host PC. In addition, such communication is widely used in industrial
automation. The
BIGdsPIC6
uses the MCP2551 circuit for CAN communication. This circuit provides an interface between the
microcontroller and some peripheral device. To enable connection between the microcontroller and MCP2551, it is necessary to set
switches 5 and 7 on the DIP switch SW14 to the ON position. Switches 6 and 8 on the DIP switch SW14 may also be used for this
purpose. Which of these switches is to be used depends solely on the arrangement of the microcontroller pins connected to CAN
communication lines. The RX line is connected to the microcontroller via RG0 and RF0 microcontroller pins, whereas the TX line is
connected to the microcontroller via RG1 and RF1 microcontroller pins.
