顯示於七段

Question

我正在寫的以下7段LCD上顯示溫度的代碼：

LCD-H301C31TF Datasheet

我使用PIC24FJ64GA006微。

我只能使用PORTB [13：6]，PORTD [0：7]，PORTE [0：7]端口引腳。

你能幫我找到更優雅的方法來替換下面的代碼嗎？

void SegLCD_Set(uint8_t Value,uint8_t Digit) 
{ 
    switch(Digit) 
    { 
     case 1: 
      if(Value==0x00){ LATB = (LATB & ~(0x7F<<6)) | (0x3F<<6); } 
      if(Value==0x01){ LATB = (LATB & ~(0x7F<<6)) | (0x0C<<6); } 
      if(Value==0x02){ LATB = (LATB & ~(0x7F<<6)) | (0x5B<<6); } 
      if(Value==0x03){ LATB = (LATB & ~(0x7F<<6)) | (0x5E<<6); } 
      if(Value==0x04){ LATB = (LATB & ~(0x7F<<6)) | (0x6C<<6); } 
      if(Value==0x05){ LATB = (LATB & ~(0x7F<<6)) | (0x76<<6); } 
      if(Value==0x06){ LATB = (LATB & ~(0x7F<<6)) | (0x77<<6); } 
      if(Value==0x07){ LATB = (LATB & ~(0x7F<<6)) | (0x1C<<6); } 
      if(Value==0x08){ LATB = (LATB & ~(0x7F<<6)) | (0x7F<<6); } 
      if(Value==0x09){ LATB = (LATB & ~(0x7F<<6)) | (0x7E<<6); } 
      break; 
     case 2: 
      if(Value==0x00){ LATD = (LATD & ~(0xFF)) | (0x3F); } 
      if(Value==0x01){ LATD = (LATD & ~(0xFF)) | (0x0C); } 
      if(Value==0x02){ LATD = (LATD & ~(0xFF)) | (0x5B); } 
      if(Value==0x03){ LATD = (LATD & ~(0xFF)) | (0x5E); } 
      if(Value==0x04){ LATD = (LATD & ~(0xFF)) | (0x6C); } 
      if(Value==0x05){ LATD = (LATD & ~(0xFF)) | (0x76); } 
      if(Value==0x06){ LATD = (LATD & ~(0xFF)) | (0x77); } 
      if(Value==0x07){ LATD = (LATD & ~(0xFF)) | (0x1C); } 
      if(Value==0x08){ LATD = (LATD & ~(0xFF)) | (0x7F); } 
      if(Value==0x09){ LATD = (LATD & ~(0xFF)) | (0x7E); } 
      break; 
     case 3: 
      if(Value==0x00){ LATE = (LATE & ~(0xFF)) | (0x3F); } 
      if(Value==0x01){ LATE = (LATE & ~(0xFF)) | (0x0C); } 
      if(Value==0x02){ LATE = (LATE & ~(0xFF)) | (0x5B); } 
      if(Value==0x03){ LATE = (LATE & ~(0xFF)) | (0x5E); } 
      if(Value==0x04){ LATE = (LATE & ~(0xFF)) | (0x6C); } 
      if(Value==0x05){ LATE = (LATE & ~(0xFF)) | (0x76); } 
      if(Value==0x06){ LATE = (LATE & ~(0xFF)) | (0x77); } 
      if(Value==0x07){ LATE = (LATE & ~(0xFF)) | (0x1C); } 
      if(Value==0x08){ LATE = (LATE & ~(0xFF)) | (0x7F); } 
      if(Value==0x09){ LATE = (LATE & ~(0xFF)) | (0x7E); } 
      break; 
     default: 
      LATB = (LATB & ~(0x7F<<6)) | (0x3F<<6); 
      LATD = (LATD & ~(0xFF)) | (0x3F); 
      LATE = (LATE & ~(0xFF)) | (0x3F); 
      break; 
    }; 

}//End SegLCD_Set 

謝謝！

我不知道，如果它是任何更優雅，但是這可能是工作...

void SegLCD_Set(uint8_t Value,uint8_t Digit) 
{ 
    unsigned char values[] = {0x3f, 0x0c, 0x5b, 0x5e, 0x6c, 0x76, 0x77, 0x1c, 0x7f, 0x7e}; 
    switch(Digit) 
    { 
    case 1: 
     LATB = (LATB & ~(0x7F<<6)) | (values[Value]<<6); 
     break; 
    case 2: 
     LATD = (LATD & ~(0xFF)) | (values[Value]); 
     break; 
    case 3: 
     LATE = (LATE & ~(0xFF)) | (values[Value]); 
     break; 

    default: 
     LATB = (LATB & ~(0x7F<<6)) | (0x3F<<6); 
     LATD = (LATD & ~(0xFF)) | (0x3F); 
     LATE = (LATE & ~(0xFF)) | (0x3F); 
     break; 
    }; 
}
