Now that the code is tested and we are able to transmit / receive a generic package, appropriately formatted, the next step is to use the interface with a program. In reception we will have an ASCII string formatted in the same way as the transmission, as shown below:ДЄ YouTube video where CAN-ISO communicates with a CAN BUS industrial device, using the вЂњCANINOвЂќ code and the вЂњLabViewвЂќ graphical interface: We send to the address 0B, the stringВ 08 07 06 05 04 03 02 01 If all the operations have been carried out correctly, the other interface will receive at the address 0A the bytes as in the sequence shown.ДЇor the reception code test, the reverse operation is performed. Recall that a hexadecimal byte is between 00 and FF.

01 02 03 04 05 06 07 08 are the 8 bytes to be sent in hexadecimal format.

(Attention) warns the interface that a new string is coming and that it must realign for a new send.

Open the serial terminal from the Arduino editor and configure it for a speed of 115200 baud, no flow control.Д®nter the following string: and press enter. Change this value in the code for a different speed. The interface is configured for a CAN communication speed of 500kbps. Once the master/slave relationship is established, the direction of control is always from the master to the slave(s).ДЇor the code test it is necessary to create a CAN-BUS micro-network, for example using two Arduino CAN-BUS interfaces.ДЇor the example code shown here we used an Arduino CAN-BUS interface connected to a commercial CAN-BUS interface. In the master/slaveВ one device or process (known as the master) controls one or more other devices or processes (known as slaves). Now we are ready to start! Code test (Transmission)ДЄ typical CAN-Bus connection in the industrial automation domain is shown in the figure, where there is a master and several multi slaves. * Get the character received from the USART */ if we get a valid byte, read analog ins: PinMode(CAN0_INT, INPUT) // Configuring pin for /INT input Serial.println('Error Initializing MCP2515.')

I have been trying with Arduino UNO + Sparkfun Shield, but i dont get any results, when everything connected, my serial console isnt sniffing any packets, i have connected all correctly i think, tried different bitRates, changed Arduino boards and shield, tried many different examples, i invested lots of hours with no profit. I need to know what way i could Read/Send CAN packets from/to BUS, i mean what tool or anything else. I have researched during some time, and i figured i need Can-bus signals to be simulated as the eps ECU is receiving ignition packets from CAN, here i go. I repair Electric powered steering systems for cars, especially Fiat/Alfa/Lancya (Delphi manufacturers) and i'm in need of making some tool to test these reparations, i mean just turning it on for example.
