LAUNCHXL-F28379D: MATLAB MODEL CAN COMMUNICATION

YUSUF KARATAS

Part Number: LAUNCHXL-F28379D

Hello everyone,

I am trying to transmit data over CAN. I am sharing block diagram below.

But obtained messages are as it seems in the following figure.

Why I am not be able to read related data. Why am I getting error ? Why cant I see sent message .

Thanks.

Hi,

It looks like bus error. It is likely that some physical connection is not OK.

Did you try terminating the CAN bus with a 120 ohm resistor.

Try to test with a known source like CCS to see if the CAN bus setup is good and working.

Then give a try from MATLAB.

Hello Venkatesh,

Thanks for your reply. I have used termination resistor.

Since I have not an on-shelf CAN code I can not use it directly. If you have, can you pass it to me ( a code for just transmit data via CAN).

Thanks.

Thanks Srinivasa,

I will try exchanging H and L pins. I hope someone will help me.

Thanks.

Dear Venkatesh,

I have found that there is a clock setting I need to change.

I am so sad that this mistake has taken my 3 days. Is there any document which declares that this change need to be done ?

Thanks.
