CAN controller
Introduction
The schematic is almost identical with the MCP2515 Development Kit from Microchip.
The LPT port of IC7 (Super-I/O) is the link between the CAN controller MCP2515 and the COM Express™
Module that acts as a microcontroller. The parallel port is used to allow the PC to communicate with
MCP2515 via SPI.
The CAN controller MCP2515 is the interface between the CAN bus and the MCU.
The CAN transceiver MCP2551 converts the differential signal on the bus to digital levels for the CAN
controller and vice versa.
