Hi! I writing a code about print to the other position custom char the value as a function. Like this code.

byte a_1[8] = {
  B00000,
  B00010,
  B11010,
  B01010,
  B01011,
  B01010,
  B00010,
  B00010,
                  };
  lcd.createChar(n, a_1);
  lcd.begin(16, 2);
  lcd.write(byte(n));

Value 'n' is set custom char position.
