it is posible to create manually a can message?

it is posible to create manually a can message in matlab/simulink?

[Image Analyst]

What is a can message? Do you mean a text message for a cell phone, or an email message? Or do you mean a popup message like you'd use msgbox() for? What exactly is the "can" you refer to? And please descrive exactly what "manually" means, as opposed to automatic or via lines of code.

Hi, I wanted to say CAN frame. I must send CAN frame, but I don't have CAN vehicle toolbox.

It's for a diagnostic tool

CAN is a vehicle bus http://en.wikipedia.org/wiki/CAN_bus

it is closely related to VAN, Vehicle Access Network

You can create the data bitstream without much difficulty, and you can NRZ encode it to a representation of the voltage bit stream. However, the serial bus for CAN is not compatible with RS232, so you would need a CAN driver chip to drive the bus. Talking to the CAN driver might require you to write some MEX code that would be operating system and hardware dependent, but potentially you might be able to use loadlib() or activex to talk to a pre-written driver.

I'm quite new in simulink. Could you please tell me how to create data bitstream? Iknow I have to integrate a diagnostic service into a model. For this I have to use some messages to acces the ECU signals. after that i have to integrate the model into Canoe. I'm a little confuse about how exactly have to do this
