Special characters andsequences listed below are used to format LCD output and control current position.ANSI C notation Hex value Description Example\f 0x0C Clear LCD and go to first position "\fHello"\r 0x0D Go to first position "\r0123"\n 0x0A Go to next string "\rHello\nWorld"\eXY 0x1B X Y Go to position X,Y "\e00Hello\e01World"Every string written to LCD will be space padded till the end of the string.Parameters· *str - LCD stringReturn valueOn success function returns 0.
