Tin can-Bus Shield V2.0

Can-BUS is a mutual industrial omnibus because of its long travel distance, medium advice speed and high reliability. It is normally constitute on modern car tools, such every bit an automotive diagnostic charabanc.

This CAN-Omnibus Shield adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver to requite your Arduino/Seeeduino Tin can-BUS adequacy. With an OBD-II converter cablevision added on and the OBD-II library imported, you lot are set to build an onboard diagnostic device or information logger.

CAN Jitney Shield V1.1	Aug x, 2013
CAN Motorbus Shield V1.2	January 5, 2015
CAN Motorcoach Shield V2.0	Aug 01,2017

What'south new in CAN BUS Shield V1.2

• Pads on the backside of PCBA
• Change terminal resistor to 120 Ohm

Alternative Choice

If your project is space limited and also don't demand other fuctions except Tin-BUS, hither is a Grove Tin can-BUS module which is Arduino compatible, more meaty and cost effective, delight click here to visit its folio.

What if I want to connect this shield to my auto

If you want to read data or control your car, there's an OBD>DB9 cablevision available for you, this cable make easier to connect to OBD-connector and DB9-connector. This cable will as well work with anything that has a OBD-connector. Add a power switch makes such a satisfying click.

USB-CAN Analyzer

If yous want a Tin Omnibus Analyzer to debug your Can Charabanc, this USB-Tin Analyzer is recommended.

Features¶

• Implements Can V2.0B speed up to i Mb/s
• SPI Interface speed up to 10 MHz
• Standard (11 bit) and extended (29 bit) data and remote frames
• Two receive buffers with prioritized message storage
• Industrial standard DB-9 connector
• LED indicators

Annotation

Tin BUS Shield Work well with Arduino UNO (ATmega328), Arduino Mega (ATmega1280/2560) as well as Arduino Leonardo (ATmega32U4).

Hardware Overview¶

1. DB9 Interface - to connect to OBDII Interface via a DBG-OBD Cable.
2. V_OBD - It gets ability from OBDII Interface (from DB9)
3. Led Indicator:
   • PWR: power
   • TX: glimmer when the data is sending
   • RX: blink when there's information receiving
   • INT: data interrupt
4. Final - CAN_H and CAN_L
5. Arduino UNO pivot out
6. Series Grove connector
7. I2C Grove connector
8. ICSP pins
9. IC - MCP2551, a high-speed CAN transceiver (datasheet)
10. IC - MCP2515, stand-alone CAN controller with SPI interface (datasheet)

Alarm

When you use more than two CAN Bus Shield in one net, y'all should have the impedance into consideration. You lot should either cut P1 in the PCB with a pocketknife, or just remove R3 on the PCB.

The Free pin is bachelor for the other usages.

CS pin

Attention

When nosotros produced the new batch of CAN-Charabanc Shield V2, the wire of the back pads was embedded inside the PCB, although the wire betwixt the pads is now not visible on the exterior, the inside is all the same connected, if you want to change the wiring of the pads, you nonetheless need to cut the wiring in the PCB first.

SPI_CS pin of V1.2 is connected to D9 by default. If you want to change to D10, delight follow beneath instructions.

• Step1: Take a look at the backside of the PCBA, you lot will discover a pad named CS.

• Step2: Cut the wire betwixt pad9 and the center pad.

• Step3:Solder the middle pad and pad ten.

Alarm

Be conscientious with the box cutter, it's easy to hurt yourself or the PCBA.

SPI pins

The SPI pins (SCK, MISO, MOSI) are routed to the ICSP pins past default. But for some boards, the SPI pins are located at D11~D13. if this happens, you need brand some change to the PCBA. Accept a look at the backside of the PCBA, in that location're three pads, MOSI, MISO and SCK, they are continued to A past default. Y'all can alter them to B if needed.

Note

For Arduino UNO, Arduino Mega, Arduino Leonardo and any others AVR based Arduino boards, it works well by default setting.

Warning

Exist careful when you are going to alter SPI pins, information technology's easy to hurt yourself or the PCBA.

Getting Started¶

Here's a simple example to show you how Tin can-BUS Shield works. In this example we demand two pieces of CAN-BUS Shields as well every bit Arduino or Seeeduino.

STEP1: What do we need

Proper name	Function	Qty	Link
CAN-BUS Shield	Tin Autobus communication	2	link
Seeeduino V4.2	Controller	2	link
Jumper Wire	connection	2	link

STEP2: Hardware Connectedness

Insert each Can-Coach Shield into Seeeduino V4.two, and connect the two Tin can-BUS Shield together via 2 jumper wires. Shown as beneath images.

Note

CAN_H to CAN_H, CAN_L to CAN_L

STEP3: Software

Delight follow how to install an arduino library procedures to install Tin can Omnibus shield library.

• Download the Seeed_Arduino_CAN Arduino library here.

Install the library to your Arduino IDE when it is downloaded.

I of the node (a node means Seeeduino + CAN_BUS Shield) acts equally master, the other acts as slaver. The master will send information to slaver constantly.

Note

Each node can deed as master earlier the code being uploaded.

Open up the transport example (File > Examples > Seeed_Arduino_CAN > send) and upload to the master.

Or copy the following to the Arduino IDE and upload:

                                                        #include                                                            <SPI.h>                                        #include                                                            "mcp2515_can.h"                                        /*SAMD core*/                                        #ifdef ARDUINO_SAMD_VARIANT_COMPLIANCE                                                            #ascertain SERIAL SerialUSB                    #else                                                            #define SERIAL Series
