📦 Package Includes

• 1 × MCP2515 CAN Bus Module with TJA1050 Transceiver

📌 Code Examples – MCP2515 CAN Bus Module (TJA1050, SPI)

📋 Overview

This module combines:

  • MCP2515 – CAN controller (SPI interface)

  • TJA1050 – CAN transceiver (physical layer)

It lets an Arduino / MCU talk on a CAN bus, commonly used in:

  • Automotive (ECU, sensors, dashboards)

  • Industrial equipment

  • Robotics and distributed control networks

🔌 Basic Wiring (Arduino UNO)

MCP2515 → Arduino UNO:

MCP2515 Pin Arduino UNO Pin
VCC 5V
GND GND
SCK D13
SI (MOSI) D11
SO (MISO) D12
CS (NSS) D10 (configurable)
INT D2 (optional but recommended)

CAN Bus Side:

TJA1050 Pin Connect To
CANH CAN High (twisted pair)
CANL CAN Low (twisted pair)

For testing, you typically use two MCP2515 modules and connect CANH↔CANH, CANL↔CANL, with a 120 Ω termination resistor at each end of the bus.

📦 Library Required

In Arduino IDE, install:

  • mcp_can library (often listed as “MCP_CAN by Cory J. Fowler”)

🧪 Example 1 – Simple Transmit (Arduino UNO)

This sends a basic CAN frame repeatedly.

#include <mcp_can.h>
#include <SPI.h>const int SPI_CS_PIN = 10;

MCP_CAN CAN(SPI_CS_PIN);

void setup() {
Serial.begin(115200);

// Initialize MCP2515 at 500 kbps
if (CAN.begin(MCP_ANY, CAN_500KBPS, MCP_8MHZ) == CAN_OK) {
Serial.println(“MCP2515 Initialized Successfully!”);
} else {
Serial.println(“Error Initializing MCP2515…”);
while (1);
}

CAN.setMode(MCP_NORMAL); // Normal mode

Serial.println(“CAN Bus Transmit Example”);
}

void loop() {
byte data[8] = {0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88};
unsigned long canId = 0x123; // Example CAN ID

byte result = CAN.sendMsgBuf(canId, 0, 8, data);

if (result == CAN_OK) {
Serial.println(“Message Sent OK”);
} else {
Serial.println(“Error Sending Message”);
}

delay(1000);
}

🧪 Example 2 – Simple Receive (Arduino UNO)

Use this on a second Arduino + MCP2515 connected to the same CAN bus.

#include <mcp_can.h>
#include <SPI.h>const int SPI_CS_PIN = 10;
const int CAN_INT_PIN = 2;

MCP_CAN CAN(SPI_CS_PIN);

void setup() {
Serial.begin(115200);
pinMode(CAN_INT_PIN, INPUT);

if (CAN.begin(MCP_ANY, CAN_500KBPS, MCP_8MHZ) == CAN_OK) {
Serial.println(“MCP2515 Initialized Successfully!”);
} else {
Serial.println(“Error Initializing MCP2515…”);
while (1);
}

CAN.setMode(MCP_NORMAL);

Serial.println(“CAN Bus Receive Example”);
}

void loop() {
if (!digitalRead(CAN_INT_PIN)) { // Interrupt low means message available
unsigned long canId;
byte len;
byte buf[8];

if (CAN.readMsgBuf(&canId, &len, buf) == CAN_OK) {
Serial.print(“ID: 0x”);
Serial.print(canId, HEX);
Serial.print(” Data: “);
for (byte i = 0; i < len; i++) {
Serial.print(“0x”);
Serial.print(buf[i], HEX);
Serial.print(” “);
}
Serial.println();
}
}
}

🔁 Two-Node Test Setup

To demonstrate the module to customers, you can describe a simple test:

  1. Node A (Sender): Arduino + MCP2515 running Transmit sketch

  2. Node B (Receiver): Arduino + MCP2515 running Receive sketch

  3. Connect:

    • CANH ↔ CANH

    • CANL ↔ CANL

    • 120 Ω termination resistor at each end of cable

  4. Power both Arduinos via USB

  5. Open Serial Monitor on the receiver board → you’ll see CAN frames arriving from Node A.

This is a nice simple “it really works” example.

⚡ ESP32 Example (SPI Pins)

ESP32 also works great with MCP2515; just adjust SPI pins & CS:

#include <mcp_can.h>
#include <SPI.h>#define SPI_CS_PIN 5
#define SPI_MISO 19
#define SPI_MOSI 23
#define SPI_SCK 18

MCP_CAN CAN(SPI_CS_PIN);

void setup() {
Serial.begin(115200);
SPI.begin(SPI_SCK, SPI_MISO, SPI_MOSI, SPI_CS_PIN);

if (CAN.begin(MCP_ANY, CAN_500KBPS, MCP_8MHZ) == CAN_OK) {
Serial.println(“MCP2515 OK on ESP32”);
} else {
Serial.println(“MCP2515 init failed”);
while (1);
}

CAN.setMode(MCP_NORMAL);
}

void loop() {
byte data[2] = {0xAA, 0x55};
CAN.sendMsgBuf(0x321, 0, 2, data);
delay(1000);
}

🧠 Tips & Notes

  • Make sure the library bitrate matches the actual CAN bus speed (common values: 125 kbps, 250 kbps, 500 kbps).

  • Most MCP2515 breakout boards use an 8 MHz crystal – hence MCP_8MHZ in the init.

  • Always use twisted pair for CANH/CANL and terminate the bus with 120 Ω at both ends.

  • You can connect to real automotive CAN with proper voltage and wiring precautions, but always respect vehicle safety and warranty considerations.
