Issue with bitReading a 10bit number

Projects Programming

Hi all,

As always, I'll keep it brief for your time.

Goal: to send a 10bit number, in the binary form, to the serial monitor (with all the leading zeros intact).

Code:

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

}

void loop () {
  byte x = 0b1000000000;
  for (int i = 9; i >= 0; i--) {
    Serial.print (bitRead (x, i));
  }
  Serial.print ("\n");
  delay (1000);
  

}

Reality:

I'm getting this (copy and pasted from serial monitor):
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000

If I recall correctly, I can only define a 1 byte binary in the Arduino environment. If this in fact is the issue, how can I "properly" display a 10bit binary number on the serial monitor?

Thank you.

ArianKS:
If I recall correctly, I can only define a 1 byte binary in the Arduino environment.

Use int x = 0x200;
or int x = (1<<9);

There are only 8 bits in a byte.

Got it, thank you!
