I am using CAN module with external loop back method , but i need to implement in full duplex communication in order to do so i found that sending and receiving side both need to send and receive transfer request.What type of transfer request does CAN needed?

Hi Karthik,

As per my understanding full duplex communication won't be possible in CAN communication. If two nodes transmit data simultaneously then the lower priority ID node will stop transmitting during arbitration phase.

Thanks & regards,

Hi Jagadish,

I tried the example progarm in Halcogen using CAN interrupt but that code also seems to not working.I configure one Rm44L920 for sending and another for recieving but CAN communication is not happening.Can you give me simple code which i could use for CAN interrupt based communication.
