Microchip Technology MCP2515DM-PCTL CAN Controller PICtail Demo Board

Microchip Technology MCP2515DM-PCTL CAN Controller PICtail Demo Board implements a simple CAN bus using two nodes. One node uses the MCP2515 Stand Alone CAN controller, while the other uses the MCP25020 CAN I/O Expander. Each Microchip Technology MCP2515DM-PCTL CAN Controller PICtail Demo Board node utilizes one input (push button) and one output (LED).

The board demonstrates a simple, inexpensive CAN bus implementation. 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.

Features

Two (2) CAN nodes consisting of
- Each node has one push button and one LED connected to the I/O
- Node A: MCP2515, PIC16F676 and an MCP2551 CAN transceiver
- Node B: MCP25020 CAN I/O Expander and MCP2551 CAN transceiver

The pushbutton 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) using the programming features of the PICkit™ 1 Flash Starter Kit or PICkit™ 2 Microcontroller Programmer. Neither header is populated
