Question

首先，我对Arduino世界很新。我认为我的代码相当简单，但它不起作用。

所以我根据自己的知识制作了一个脚本，将十进制值转换为8位二进制值。所以只有0到255十进制到二进制，然后检查将其转换回十进制。

现在我很困惑为什么我的代码看起来像是在工作但只有三个！

如果有人可以就此事提供帮助，我们将不胜感激。

这是我的代码：

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;
}

现在注意3值。这就是它开始被抵消的地方。据我所知，一切都是正确的。谁能发现错误？

Answer 1

由于你要经历一个0到1的数组，你应该使用位移：

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

Answer 2

pow（）给出输出为double。像保罗建议的那样做。

如果arduino拥有它，你也可以尝试包括math.h然后使用int（ceil（pow（int a，int b）））来获得确切的值。据我所知.. pow（）给出的输出为双倍，可能像3.999的东西，默认情况下int在其中做地板...所以它转换为3. ceil（）将它带到下一个最大的int值。它可能有用。

Arduino将十进制转换为二进制到十进制
