CAN communication between two LPC1768 boards

[Laxmanrao]

Hii,

 

 

 I am working on CAN Communication between two LPC1768. I want to collect ADC values from one LPC1768 controller and i will display data to other lpc1768 controller which on 2×16 LCD. I tried sample code which is for loop back of same controller.my problem is how to transmitt to other controller…

 

 

    if (CAN_RxRdy[0]  ) {                           /* rc message on CAN Controller #1 */

      CAN_RxRdy[0] = 0;

 

      val_Rx = CAN_RxMsg[0].data[0];

    }

Hi, For communication between two different LPC1768 you should use transceiver chip which can be (TJA1040 or MCP2551) because these series has no inbuilt transceivers .you can find many circuits giving the hardware connection of this transceiver chips to any CAN Controller.
