Topic: CAN 29bit 250/500K

Hi Konstantin, I try to read CAN 29bit at 250 and 500K, but I didn't have answer, I sent commands to have answer but nothing come to me.
CANNY 7 is compatible with CAN 29bit? If yes, how can I do to send and receive data about it?
In CAN 11bit I tried perfectly, I sent and received data normaly, so in 250 as 500K.

Thanks by your support.

You can send to CAN in Extended Frame Format (29bit ID) from diagram and from Canny CAN Monitor too.
Please see online documentation: http://wiki.cannylogic.com/index.php?ti … CAN_Driver and Help in main menu of Canny CAN Monitor.

Hi Konstantin,

I tried to follow all steps to can communicate with CAN 29bit, but I not have success, in CAN 11bit I communicate normally, please check the answers bellow.

In 11bit all come ok
sent: 7DF 02 01 0D 00 00 00 00 00 00
Receive: 7E8 03 41 0D 23 00 00 00 00

In 29bit not ok,

sent: 18DB33F1 02 01 0D 00 00 00 00 00
sent: 18DB33F1 02 01 0D 00 00 00 00 00 1
sent: 18DB33F1 02 01 0D 00 00 00 00 00 EXT=1

In 29bit case, the data not arrive at ECM, I know this because I put oscilloscope in CANH and CANL and not happens when I sent data.

I should receive the data: 18DA10F1 03 41 0D 23 00 00 00 00

I believe that Im doing anything wrong
