Do you have a LCD display?
If not then make sure that you use the software for
part I of the article series. Part II (linuxI2Ctemp_lcd-0.5) will not
work because there is no response from the LCD display. The microcontroller
will then hang and wait for the display to answer, which will never happen.

I made all the connections and I read the temp from the RS232 port but I do not see anything in the display...I tried with 2 different display but no line comes out. Do I have to remove the resistor for the contrast?
Thank you in advance

max contrast is when you connect the contrast pin to GND.
However check also each and every pin against the datasheet.
Especially make sure that you do not mix up +5V and GND at the
