CAN communication & transciever

Sneha Thakur

Hi

I am trying to work with CAN communication in F28335.I am facing issues with it,as I am not able to transmit the data from one DSP to another.The can back to bac program works fine,but when it comes to transmit from CAN-A to CAN-B,it doesnot.

My transciever connections works fine and gives CANh-CANL waveforms when given a high pulse at TXD pin from GPIO pin but the same connection doesnt give any pulse when TXD is given input from CANTX pin.

I am stuck with the issue from a long time and can not make out if its hardware/software issue.

Your help would be appreciated.

thanks &Regards

Sneha
