而且， 我在engine_control.c文件中已经包含了下面的头文件。
#include <nuttx/can.h>
#include <nuttx/can/can.h>
#include <netpacket/can.h>

哪里找不到就在哪里加上它的结构体。 #if 1 #define CAN_MAX_DLEN 8 struct can_frame { canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */ uint8_t can_dlc; /* frame payload length in byte ...

#if 1
#define CAN_MAX_DLEN 8

struct can_frame
{
  canid_t can_id;   /* 32 bit CAN_ID + EFF/RTR/ERR flags */
  uint8_t  can_dlc; /* frame payload length in byte (0 .. CAN_MAX_DLEN) */
  uint8_t  __pad;   /* padding */
  uint8_t  __res0;  /* reserved / padding */
  uint8_t  __res1;  /* reserved / padding */
  uint8_t  data[CAN_MAX_DLEN] __attribute__((aligned(8)));
};
