Microchip | MCP2515DM-PCTL

MCP2515DM-PCTL CAN Controller PICtail Demonstration Board implements a simple CAN bus using two nodes. One node uses the MCP2515 Stand Alone CAN controller and the other node uses the MCP25020 CAN I/O Expander.

The boards demonstrate a simple, inexpensive implementation of a CAN bus. The MCP2515 node transmits its input (push button) information at regular intervals and request input (push button) information from the MCP25020 at regular intervals. An LED on each node reflects the state of the other node's push button.

Features:

• Two CAN nodes consisting of:
• Node A: MCP2515, PIC16F676 and a MCP2551 CAN transceiver
• Node B: MCP25020 CAN I/O Expander and MCP2551 CAN transceiver
• Each node also has one push button and one LED connected to the I/O
• The push button state from each node is sent to the other node via a CAN message
• Two headers on Node A, used for programming the PICmicro® Microcontroller Unit (MCU)

Kit includes:

• One MCP2515 PICtail Demo Board with two CAN nodes
• One node includes a PIC16F676, a MCP2515 CAN controller and a MCP2551 transceiver
• The other node includes a MCP25020 CAN I/O expander and an MCP2551 transceiver
• The CAN nodes can be physically separated by snapping them apart at the perforation
• One power/bus cable for connecting the two PCB sections together
• MCP2515 CAN Controller PICtail Demo Board users guide
