（1）项目功能介绍：按键1、图片手动切换，可向前向后观看，按4键退出观看。

按键2、图片自动顺序播放，按4键退出观看。

按键3、显示当前时间，按4键退出观看。

按键4、退出当前选择的功能。

（2）项目代码举例介绍：

1、

TIM_init_typedef tim_init_typedef;
GPIO_Init_Typedef gpio_init_typedef;
UART_init_typedef uart_init_typedef;
//RTC_struct_init rtc_struct_init;

gpio_init_typedef.mode=GPIO_MODE_OUT;
gpio_init_typedef.mode=GPIO_MODE_IN;
gpio_init_typedef.udp=GPIO_UDP_UP;
gpio_init_typedef.pinx=GPIO_PIN25|GPIO_PIN26;
GPIO_INIT(GPIOA,GPIO_PIN25|GPIO_PIN26,gpio_init_typedef);
gpio_init_typedef.pinx=GPIO_PIN5|GPIO_PIN6;
GPIO_INIT(GPIOB,GPIO_PIN5|GPIO_PIN6,gpio_init_typedef);
GPIO_INIT(GPIOF,GPIO_PIN0|GPIO_PIN1|GPIO_PIN2|GPIO_PIN3,gpio_init_typedef);

gpio_init_typedef.mode=GPIO_MODE_ALT1;
gpio_init_typedef.pinx=GPIO_PIN0;
//GPIO_INIT(GPIOB,GPIO_PIN0,gpio_init_typedef);

uart_init_typedef.baudrate=115200;
uart_init_typedef.mode=mode_rx_tx;
uart_init_typedef.parity=parity_no;
uart_init_typedef.stop=stop_one;
uart_init_typedef.wordwidth=wordwidth_8bit;
uart_init(UART0,uart_init_typedef);
// LED_INIT();
// uart_init();

UART_interrupt_init(UART0,(U32)UART0_IRQ);
IRQ_INTMask_init(INT_UART0,ENABLE);
IRQ_INTSUBMask_init(SUB_INT_RXD0,ENABLE);

// TIM_init(time_ch0,tim_init_typedef);
// TIM_interrupt_init(time_ch0,(U32)TIMER0_IRQ);
// IRQ_INTMask_init(INT_TIMER0,ENABLE);
//
//LCD_clear(0);
ADC_init(AIN_ch0,ADC_10bit_mode);
ADC_interrupt_init(AIN_ch0,(U32)ADC_IRQ);
IRQ_INTMask_init(INT_ADC,ENABLE);
IRQ_INTSUBMask_init(SUB_INT_ADC,ENABLE);

主函数中，调用相关函数前需要进行初始化处理。创建的对象要放在主函数的开头，放在下面会出错。

2、

while(1)

{

if(GPIO_readbit(GPIOF,GPIO_PIN0) == 0)

{

count++;

if(count == 5)

{

count = 0;

}

if(count == 0)

{

LCD_display_picture(0,0,480,272,gImage_641);

}

if(count == 1)

{

LCD_display_picture(0,0,480,272,gImage_642);

}

if(count == 2)

{

LCD_display_picture(0,0,480,272,gImage_643);

}

if(count == 3)

{

LCD_display_picture(0,0,480,272,gImage_644);

}

if(count == 4)

{

LCD_display_picture(0,0,480,272,gImage_655);

}

break;

}

if(GPIO_readbit(GPIOF,GPIO_PIN1) == 0)

{

count--;

if(count < 0)

{

count = 4;

}

if(count == 0)

{

LCD_display_picture(0,0,480,272,gImage_641);

}

if(count == 1)

{

LCD_display_picture(0,0,480,272,gImage_642);

}

if(count == 2)

{

LCD_display_picture(0,0,480,272,gImage_643);

}

if(count == 3)

{

LCD_display_picture(0,0,480,272,gImage_644);

}

if(count == 4)

{

LCD_display_picture(0,0,480,272,gImage_655);

}

if(GPIO_readbit(GPIOF,GPIO_PIN3) == 0)

{

Interface();

m = -1;

break;

}

实现功能1，前后翻看照片。初始化设置了各个按键，然后定义按下1键顺序观看，2键逆序观看。如果刚看到最后一张照片或者最开始的照片，自动切换到头和尾。4键跳出该功能。

3、

while(1)
      {
       RTC_get_time(&rtc_struct_init); //»ñÈ¡Ê±¼äÖµ
       sprintf(time,"%04x-%02X-%02x %02x:%02x:%02x",rtc_struct_init.year,rtc_struct_init.month,
        rtc_struct_init.day,rtc_struct_init.hour,rtc_struct_init.minute,rtc_struct_init.second);
       //sprintf(time,"%02x:%02x:%02x",rtc_struct_init.hour,rtc_struct_init.minute,rtc_struct_init.second);
       LCD_Display_String(148,100,0xff,time);
       delay_ms(300);
       LCD_Display_String(148,100,0xffffff,time);

       if(GPIO_readbit(GPIOF,GPIO_PIN3) == 0)
       {
         Interface();
            m = -1;
         break;
       }

显示时间函数。每次显示时间之后要刷新一下，不然会第二次显示的数字与第一次显示的叠加。

4、

i = 0;
     while(i<5)
     {
      if(GPIO_readbit(GPIOF,GPIO_PIN3) == 0)
      {
        Interface();
        m = -1;
        break;
      }

      LCD_display_picture(0,0,480,272,picture[i]);

      if(GPIO_readbit(GPIOF,GPIO_PIN3) == 0)
      {
        Interface();
        m = -1;
        break;
      }

      delay_ms(500);
      i++;
      if(i == 5)
      {
       i = 0;
      }

      if(GPIO_readbit(GPIOF,GPIO_PIN3) == 0)
      {
        Interface();
        m = -1;
        break;
      }
     }

自动播放图片，该功能有一个缺陷，退出的时候需要按键许多次，除非按键一次就接收到。多次实验，我猜想应该最后播放图片之后要延迟一会，正好与按键信号冲突，未接收到。所以我在功能实现前后都加了退出函数。

5、

LCD_display_picture(10,15,458,68,gImage_111);

LCD_Display_16x16(65+100, 75,RED,hanzi[6]);

LCD_Display_16x16(85+100, 75,RED,hanzi[7]);

LCD_Display_String(105+100,75,0xff,"1:");

LCD_Display_16x16(125+100, 75,RED,hanzi[10]);

LCD_Display_16x16(145+100, 75,RED,hanzi[11]);

LCD_Display_String(165+100,75,0xff,"(");

LCD_Display_16x16(185+100, 75,RED,hanzi[15]);

LCD_Display_16x16(225+100, 75,RED,hanzi[18]);

LCD_Display_16x16(245+100, 75,RED,hanzi[19]);

LCD_Display_String(265+100,75,0xff,")");

LCD_Display_16x16(65+100, 125,RED,hanzi[6]);

LCD_Display_16x16(85+100, 125,RED,hanzi[7]);

LCD_Display_String(105+100,125,0xff,"2:");

LCD_Display_16x16(125+100, 125,RED,hanzi[10]);

LCD_Display_16x16(145+100, 125,RED,hanzi[11]);

LCD_Display_String(165+100,125,0xff,"(");

LCD_Display_16x16(185+100, 125,RED,hanzi[16]);

LCD_Display_16x16(205+100, 125,RED,hanzi[17]);

LCD_Display_16x16(225+100, 125,RED,hanzi[18]);

LCD_Display_16x16(245+100, 125,RED,hanzi[19]);

LCD_Display_String(265+100,125,0xff,")");

LCD_Display_16x16(65+100, 175,RED,hanzi[6]);

LCD_Display_16x16(85+100, 175,RED,hanzi[7]);

LCD_Display_String(105+100,175,0xff,"3:");

LCD_Display_16x16(125+100, 175,RED,hanzi[8]);

LCD_Display_16x16(145+100, 175,RED,hanzi[9]);

LCD_Display_16x16(65+270,220,0xff,hanzi[0]);

LCD_Display_16x16(85+270,220,0xff,hanzi[1]);

LCD_Display_16x16(105+270,220,0xff,hanzi[2]);

LCD_Display_16x16(125+270,220,0xff,hanzi[3]);

LCD_Display_16x16(145+270,220,0xff,hanzi[4]);

LCD_Display_16x16(165+270,220,0xff,hanzi[5]);

主界面显示函数，通过该工具将需要的字体转换成代码。通过该将需要用到的图片转换成代码。再通过显示函数，显示出来。
