Problem with I2C Scan code

[thierry7100]

Hi,

I have opened this issue back in April 2018, but there is still some problems

1. Within LCD I2C, the code is still incorrect, there are simple quotes instead of double quotes
   Serial.println('I2C scanner. Scanning ...');
   byte count = 0;

Wire.begin();
for (byte i = 8; i < 120; i++)
{
Wire.beginTransmission (i);
if (Wire.endTransmission () == 0)
{
Serial.print ('Found address: ');
Serial.print (i, DEC);
Serial.print (' (0x');
Serial.print (i, HEX);
Serial.println (')');
count++;
delay (1);
} // end of good response
} // end of for loop
Serial.println ('Done.');
Serial.print ('Found ');
Serial.print (count, DEC);
Serial.println (' device(s).');

When using I2C block, the problem exists but some strings are enclosed between double quotes (correct) and some are enclosed between double quotes.

Serial.println('I2C scanner. Scanning ...');
byte count = 0;

Wire.begin();
for (byte i = 8; i < 120; i++)
{
Wire.beginTransmission (i);
if (Wire.endTransmission () == 0)
{
Serial.print ("Found address: ");
Serial.print (i, DEC);
Serial.print (" (0x");
Serial.print (i, HEX);
Serial.println (")");
count++;
delay (1);
} // end of good response
} // end of for loop
Serial.println ('Done.');
Serial.print ('Found ');
Serial.print (count, DEC);
Serial.println (' device(s).');

In which category is this code ? Which LCD screen ?
Could you explain "strings are enclosed between double quotes (correct) and some are enclosed between double quotes"
Thanks.
