Hi,
Do you have the Pro2 PLUS powered by the regulated 9V external power supply?
Also check again the connections to the TFT display. This display doesn't use the MISO line, leave it unconnected.
Software should always be configured to suit the installed sensors and / or hardware.
If you have programed the Arduino, with the default values, it will not work with the 20x4 LCD, as by default it is configured for a TFT display.
Every time you post a question, please report back if the answer solved the problem. This will help me to better help you, and will help others too.

i download original software without modified values, it's the same problem.
Perhaps a problem with arduino?
have you an idea?
