IntroductionCAN BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools, such as an automotive diagnostic bus. This CAN BUS Shield adopts MCP2. CAN Bus controller with SPI interface and MCP2. CAN transceiver to give your ArduinoSeeeduino CAN BUS capability. With an OBD II converter cable added on and the OBD II library imported, you are ready to build an onboard diagnostic device or data logger. Version. This document applies to the following version of products Whats new in CAN BUS Shield V1. Pads on the backside of PCBAChange terminal resistor to 1. Ohm. Alternative Choice. If your project is space limited and also dont need other fuctions except CAN BUS, here is a Grove CAN BUS module which is Arduino compatible, more compact and cost effective, please click here to visit its page. What if I want to connect this shield to my car. If you want to read data or control your car, theres an OBD DB9 cable available for you, this cable make easier to connect to OBD connector and DB9 connector. This cable will also work with anything that has a OBD connector. Add a power switch makes such a satisfying click. USB CAN Analyzer.

CS pin. SPICS pin of V1. D9 by default. If you want to change to D1. Step. 1 Take a look at the backside of the PCBA, you will find a pad named CS. Step. 2 Cut the wire between pad. Step. 3 Solder the middle pad and pad 1. Warning. Be careful with the box cutter, its easy to hurt yourself or the PCBA. SPI pins. The SPI pins SCK, MISO, MOSI are routed to the ICSP pins by default. But for some boards, the SPI pins are located at D1. D1. 3. if this happens, you need make some change to the PCBA. Take a look at the backside of the PCBA, therere three pads, MOSI, MISO and SCK, they are connected to A by default. You can change 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. Be careful when you are going to change SPI pins, its easy to hurt yourself or the PCBA. San Sebastian College Bar Review Program. Getting StartedHeres a simple example to show you how CAN BUS Shield works. In this example we need 2 pieces of CAN BUS Shields as well as Arduino or Seeeduino. STEP1 What do we need. Name. Function. Qty. Link. CAN BUS Shield. CAN Bus communication. Seeeduino V4. 2. Controller. Jumper Wireconnection. STEP2 Hardware Connection. Insert each CAN BUS Shield into Seeeduino V4. CAN BUS Shield together via 2 jumper wires. Shown as below images. Note. CANH to CANH, CANL to CANLSTEP3 Software. Please follow how to install an arduino library procedures to install CAN BUS shield library. Click on below button to download the library. Install the library to your Arduino IDE when it is downloaded. One of the node a node means Seeeduino CANBUS Shield acts as master, the other acts as slaver. The master will send data to slaver constantly. Note. Each node can act as master before the code being uploaded. Open the send example File Examples CANBUSShield master send and upload to the master. Open the receivecheck example File Examples CANBUSShield master receivecheck and upload to the slaver. STEP4 View Result. Open the Serial Monitor of Arduino IDEslaver, you will get the data sent from the master. APIs1. Set the Baud rateThis function is used to initialize the baud rate of the CAN Bus system. The available baud rates are listed as follows define CAN5. KBPS 1. define CAN1. KBPS 2. define CAN2.

Set Receive Mask and FilterThere are 2 receive mask registers and 5 filter registers on the controller chip that guarantee you getting data from the target device. They are useful especially in a large network consisting of numerous nodes. We provide two functions for you to utilize these mask and filter registers. They are Mask initMaskunsigned char num, unsigned char ext, unsigned char ul. Data. Filter initFiltunsigned char num, unsigned char ext, unsigned char ul. Data. num represents which register to use. You can fill 0 or 1 for mask and 0 to 5 for filter. Data represents the content of the mask of filter. Check ReceiveThe MCP2. Use the following function to poll for received frames. INT8. U MCPCAN check. Receivevoid. The function will return 1 if a frame arrives, and 0 if nothing arrives. Get CAN IDWhen some data arrive, you can use the following function to get the CAN ID of the send node. INT3. 2U MCPCAN get. Can. Idvoid. 5. Send DataCAN. Msg. BufINT8. U id, INT8. U ext, INT8. U len, databuf. It is a function to send data onto the bus. In which id represents where the data comes from. For example, In the send example, we have unsigned char stmp8 0, 1, 2, 3, 4, 5, 6, 7. CAN. send. Msg. Buf0x. Receive DataThe following function is used to receive data on the receive node CAN. Msg. Bufunsigned char len, unsigned char buf. In conditions that masks and filters have been set. This function can only get frames that meet the requirements of masks and filters. Generate a New Baud.
