The program:

#include <stdio.h>
#include <stdint.h>

#include "ov7670reg.h"

#define OV7670_ADDR 0x42

#define HEIGHT 120

#define WIDTH
uint16_t frame1[ HEIGHT * WIDTH ];
uint16_t frame2[ HEIGHT * WIDTH ];
uint32_t ov7670_set(uint8_t addr,uint8_t val);
uint8_t ov7670_get(uint8_t addr);
void ov7670_init(void);
void ov7670_readframe(void);
void ov7670_clear_buffer(void);
void ov7670_check_missing(void);
The error is from bold part!!!!!!!!
