Adding a leading 0 to incoming HEX data for conversion to binary

Hi Paul!
Ok, then - how do I get the whole CAN Message converted to Binary with the leading zeros?
So:

A7 03 B4 9D 00 BB 07 7D

Should be

10100111000000111011010010011101000000001011101100000111011111101

If I tried by just saying:

 for(byte i = 0; i<len; i++)
{
    
    Serial.print(rxBuf[I],BIN);
     
}

But - the leading zeros are not there :frowning:
