hello,
        i am  using lpc4357 board provided by nxp (philips)....on the other hand i have an lpc17xx board,from  last few days i have been working for data transfer between these two boards via a CAN BUS.....i am using C_CAN0 peripheral in lpc4357 board ....it is working fine for the transmitting the databytes from lpc43xx to lpc17xx board....somehow i am not receiving the data or  any kind of interrupt on receiving end....i have tested lpc17xx board with other nodes it is working perfect ......i guess it is problem with the lpc43xx board while reception of the databytes...anybody please help me to crack this problem.....and suggest me a sample code for the C_CAN0 peripheral Tx and Rx....
             thanks....

thanks for reply,
                             no i m not overclocking the CAN peripheral clock frequency. I have applied only 12MHZ OF periphetal frequency for that C_CAN0 peipheral. i have already refered that link you have listed above....it may be another issue that i m facing while reception of the data.....

You aren't overclocking it, are you?

Hi Friends,

I have a similar problem. The LPCOPEN example works with specific IDs, but not any other.
I have CAN0 transmitting and CAN1 receiving. Only for specific message IDs the data transfer occurs. It seems to be a problem of acceptance filtering.
Tried everything I could think off with masking and arbitration registers, but I have not found a working solution as yet.

Any suggestions ?

Cheers, Nicholas

yes, i have already tried the LPCopen source code, it is working fine for the BASIC , LOOPBACK mode and also transmission of the data bytes to the other peripheral on lpc17xx board, but somehow i am not managing to get the interuupt while i m receving the data from that lpc17xx board. i will be thankful to u if u send me the link for the runnig code for receiving datas from other nodes or you plzz send me the code in my e-mail adress : nirav_bhatt07@yahoo.in.

Hi, have you tried to use the can sample project from the LPCOpen package?
