液晶显示, include, BSP, pi, OV7725

本来想把摄像机和触摸屏的功能合并到一起，但是我把摄像机的功能移植到触摸屏的时候，即使不用触摸屏的功能，液晶也一直显示红色，具体的程序如下：
#include &quot;stm32f10x.h&quot;
#include &quot;bsp_usart1.h&quot;
#include &quot;bsp_ili9341_lcd.h&quot;
#include &quot;bsp_sdfs_app.h&quot;
#include &quot;bsp_bmp.h&quot;
#include &quot;bsp_SysTick.h&quot;
#include &quot;bsp_touch.h&quot;
#include &quot;bsp_spi_flash.h&quot;
#include &quot;bsp_led.h&quot;
#include &quot;even_process.h&quot;
#include &quot;bsp_ov7725.h&quot;
extern uint8_t Ov7725_vsync;
int main(void)
{
      //uint8_t k;
      LCD_Init();
      //LCD_Clear(0, 0, 240, 320, WHITE);
      Sd_fs_init();
      USART1_Config();
      SysTick_Init();
      //LED_GPIO_Config();
      SPI_FLASH_Init();
      Ov7725_GPIO_Config();
      while(Ov7725_Init() != SUCCESS);
      VSYNC_Init();
      Ov7725_vsync = 0;
      //Touch_Init();
      /*
      #if 1
      SPI_FLASH_BufferRead(&cal_flag, 0, 1);
      if( cal_flag == 0x45 )
      {
            SPI_FLASH_BufferRead((void*)cal_p, 1, sizeof(cal_p));
            SPI_FLASH_CS_HIGH();
            for( k=0; k<6; k++ )
            printf(&quot;\r\n rx = %LF \r\n&quot;,cal_p[k]);
      }
      else
      {
         while(Touch_Calibrate() !=0);
      }
      #elif 0
      while(Touch_Calibrate() !=0);
      #endif*/
      while(1)
      {
            if( Ov7725_vsync == 2 )
            {
                  FIFO_PREPARE;
                  ImagDisp();
                  Ov7725_vsync = 0;
            }
      }

}
