Hi Chandru I did my early testing using an internal loopback feature, which made it easier to receive data, without worrying about cables. You could look at the flags to see if the Receive buffer became full, then you would know that the packet "got there".

Subject: [motoroladsp] Receiving Messages on DSP56F805 Hi, I am Chandru. I am trying to program DSP56f805 to send and receive CAN messages. I am able to transmit messages and store them in the Transmt buffers(CAN_TB0_DSR's).I have also setup the identifiers and the mask registers. I also cleared the TXE0 flag after storing the msg. I dont know how to push the message out to the MSCAN bus. I might be missing some register setup here. For the receive I have used a ISR using #pragma interrupt. But the program does not seem to enter the Receive function. It will be gr8 if i culd get some example code for sending and receiving of Messages on dsp56f805. Regards, Chandru
