Microchip CAN Controller PICtail MCP2515 Demonstration Board MCP2515DM-PCTL

The MCP2515 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. Each node utilizes one input (push button) and one output (LED). This boards demonstrates a simple implementation of a CAN bus. The MCP2515 node transmits its input (push button) information at regular intervals and requests 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.

Node A: MCP2515, PIC16F676 MCU and MCP2551 CAN transceiver
Node B: MCP25020 CAN I/O Expander and MCP2551 CAN transceiver
Two headers on Node A for programming the PIC MCU using the PICkit™ 1 Flash Starter Kit or PICkit™ 2 Programmer
