標題: STM32F407用0.96寸OLED顯示屏實現按鍵切換屏幕源程序
//主要程序代碼如下所示:

int main(void)

{
u8 key;
Stm32_Clock_Init(336,8,2,7);//設置時鐘,168Mhz
delay_init(168); //延時初始化
uart_init(84,115200);  //初始化串口波特率為115200
LED_Init();    //初始化LED
  OLED_Init(); //初始化OLED
KEY_Init(); //初始化與按鍵連接的硬件接口
LED0=!LED0;
while(1)
{
  key=KEY_Scan(0);  //得到鍵值
  if(key)
  {
switch(key)
{
case KEY0_PRES:
   OLED_ShowString(0,0,"music",12);
   OLED_ShowString(0,10,"hello",12);
   OLED_ShowString(0,20,"cycle",12);
   OLED_ShowString(0,30,"world",12);
   OLED_Refresh_Gram();//更新顯示到OLED
   delay_us(1000);
      break;
      case KEY1_PRES:
      OLED_ShowString(0,0,"enter",12);
      OLED_ShowString(0,10,"dream",12);
   OLED_ShowString(0,20,"eager",12);
   OLED_ShowString(0,30,"drink",12);
   OLED_Refresh_Gram();//更新顯示到OLED
   delay_us(1000);
      break;
case KEY2_PRES:
      OLED_ShowString(0,0,"final",12);
      OLED_ShowString(0,10,"flash",12);
   OLED_ShowString(0,20,"float",12);
   OLED_ShowString(0,30,"fruit",12);
   OLED_Refresh_Gram();//更新顯示到OLED
   delay_us(1000);
      break;
}
  }else delay_ms(10);
}
}
