CAN_msg

The CAN_msg type is defined in rtx_can.h. It specifies the CAN message structure used by the CAN driver routines. The CAN_msg type is defined as:

typedef struct
{
U32 id;        /* 11/29 bit message ID              */
U8  data[8];   /* Data field                        */
U8  len;       /* Length of data field in bytes     */
U8  ch;        /* Object channel                    */
U8  format;    /* 0-STANDARD, 1-EXTENDED IDENTIFIER */
U8  type;      /* 0-DATA FRAME, 1-REMOTE FRAME      */
}
CAN_msg;

and is used as shown in the following example:

#include <rtx_can.h>
.
.
.
CAN_msg msg_buf =
  {
  33,                           // ID
  { 0x00, 0x00, 0x00, 0x00,
    0x00, 0x00, 0x00, 0x00 },   // Data
  1,                            // Length
  1,                            // Channel
  STANDARD_FORMAT,              // Format
  DATA_FRAME                    // Type
  };
.
.
.
CAN_send (2, &msg_buf, 0x0F00);
