how to initialize the CAN in the network

I'm unfamiliar wiht the chip.

There are two issues: What are the parameters for your network, and how do you set your chip to use those parameters. The latter is found in your chip's datasheet. The former only you can know. Although the J1939 standard will help. Bosch had an excellent paper describing bit timings somwhere out there on the web. J1939 is 250 kHz, but that doesn't tell you all you need to know about bit timing.

J1939 is a standard for vehicle networks, and is available (for a price) from SAE. There's no other (legal) way to get it. It is not specific to your chip, or any chip for that matter. You can save a lot of work by buying J1939 code from a third party, like Vector-Cantech. Your IDE is the least of your worries. There is much for you to learn.

Try looking at the can-cia web site. A lot of basic information you need to know is there, and it might get you off in the right direction.

Change is inevitable, progress is not.

As far as I remember you can find some example code for handling the Fujitsu CAN module on the Fujitsu web site. The bit time calculation, obtaining the values for the CAN controllers bit timing registers, can easily be performed using the form at

(the Philips table can be used for Fujitsu). J1939 is independent from any specific hardware manufacturer. Try to get the standard from the SAE

There's

which I think is the one you are referring to. The CAN 2.0 spec is at

hi dave!

Thank you for your valuable suggestions on CAN. i'll have the detailed study on those things and then post message if i have any doubt
