Arduino的轉換十進制轉換爲二進制到十進制

首先，我很新的Arduino的世界。我認爲我的代碼雖然很簡單，但它不起作用。Arduino的轉換十進制轉換爲二進制到十進制

所以我做一個劇本，我自己的知識十進制值轉換爲8位二進制值。因此，對二進制只有0到255十進制，然後將其轉換回十進制。

現在我很困惑，爲什麼我的代碼看起來像它的工作，但只有等到三！

如果有人可以幫助在這個問題上，這將不勝感激。

這裏是我的代碼：

void setup() { 
    Serial.begin(9600); 
} 

void loop() { 
    for(int i=0;i<=255;i++) { 
    Serial.print("DecToBin: "); 
    Serial.print(i); 
    Serial.print(" -> "); 
    boolean Bin[] = {0,0,0,0,0,0,0,0}; 
    convertDecToBin(i,Bin); 
    for(int j = 0;j<8;j++) 
     Serial.print(Bin[j]); 
    Serial.print(" -> "); 
    Serial.print(convertBinToDec(Bin)); 
    Serial.print("\n"); 
    } 
    delay(1000000); 
    // Very long delay to emulate only one "Execution" of the loop() 
} 

/* 
The following function convert any int from 0-255 to binary. 
You need to pass the int as agrument. 
You also need to pass the 8bit array of boolean 
*/ 
void convertDecToBin(int Dec, boolean Bin[]) { 
    for(int i = 7 ; i >= 0 ; i--) { 
    if(pow(2, i)<=Dec) { 
     Dec = Dec - pow(2, i); 
     Bin[8-(i+1)] = 1; 
    } else { 
    } 
    } 
} 

/* 
This following function will convert any 8 bit array of boolean to a Decimal number. 
you need to pass an boolean array of 8 bits 
function return a int 
*/ 
int convertBinToDec(boolean Bin[]) { 
    int ReturnInt = 0; 
    for(int i = 0;i<8;i++) { 
    if(Bin[7-i]) { 
     Serial.print("2^"); 
     Serial.print(i); 
     ReturnInt = ReturnInt + (int)pow(2, i); 
     Serial.print("="); 
     Serial.print((int)pow(2, i)); 
     Serial.print("+"); 
    } 
    } 
    Serial.print(","); 
    return ReturnInt; 
}

現在注意3值。這就是它開始抵消的地方。據我所知，一切都是正確的。任何人都可以發現錯誤？

不要使用浮點運算，對於具有確切的整數結果簡單的整數運算。而不是'pow（2，i）'使用'（1 << i）'。 –

既然你正在經歷的1的陣列0-7，你應該用位移位：

int convertBinToDec(boolean Bin[]) { 
    int ReturnInt = 0; 
    for (int i = 0; i < 8; i++) { 
    if (Bin[7 - i]) { 
     Serial.print("Set Bit "); 
     Serial.print(i); 
     ReturnInt += 1<<i; 
     Serial.print(" ==> "); 
     Serial.print(1<<i); 
     Serial.print(", "); 
    } 
    } 
    return ReturnInt; 
} 

DecToBin: 1 -> 00000001 -> Set Bit 0 ==> 1, 1 
DecToBin: 2 -> 00000010 -> Set Bit 1 ==> 1, 2 
DecToBin: 3 -> 00000011 -> Set Bit 0 ==> 1, Set Bit 1 ==> 1, 3 
DecToBin: 4 -> 00000100 -> Set Bit 2 ==> 2, 4 
DecToBin: 5 -> 00000101 -> Set Bit 0 ==> 1, Set Bit 2 ==> 2, 5 
DecToBin: 6 -> 00000110 -> Set Bit 1 ==> 1, Set Bit 2 ==> 2, 6 
DecToBin: 7 -> 00000111 -> Set Bit 0 ==> 1, Set Bit 1 ==> 1, Set Bit 2 ==> 2, 7 
DecToBin: 8 -> 00001000 -> Set Bit 3 ==> 4, 8

感謝您的幫助！有用！我不明白位移，但我正在研究它。但我仍然非常困惑，爲什麼代碼不起作用一開始與戰俘。 –

將'+ ='更改爲'| ='可能會稍微快一點，因爲它只是設置位。我不確定 - 我會閱讀數據表。 – zbw

沒關係，他們都需要一個循環：[從這裏開始，第616頁]（http://www.atmel.com/images/Atmel-8271-8-bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA- 168A-168PA-328-328P_datasheet_Complete.pdf） – zbw

pow（）給出了雙倍的輸出。照保羅所說的去做。

您也可以嘗試，包括文件math.h如果Arduino的擁有它，然後使用INT（小區（POW（INT A，INT B）））得到確切的價值。據我可以看到.. pow（）給出的輸出可能是3.999，而默認情況下，int就是在其中執行地板......所以它轉換爲3. ceil（）將其轉換爲下一個最大的int值。它可能工作。
