Arduino Converting Decimal to Binary to Decimal

First off, I'm very new to the Arduino world. I think my code is fairly simple though, but yet it doesn't work.

So I'm making a script for my own knowledge converting decimal values to 8-bit binary values. So only 0 to 255 decimal to binary and then for checking converting it back to decimal.

Now I'm very confused why my code looks like it's working but only until three!

If anyone could help on this matter, it would be greatly appreciated.

Here is my code:

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;
}

Now pay attention to the 3 value. That's where it starts being offset. To my knowledge everything is correct. Can anyone spot the mistake?

Solution

  • Since you are going through an array 0-7 of 1s, you should be using bit shifting:

    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
