This topic pretends to be a hint for everyone that are planing, or are starting now building an WeatherDuino Pro 2 system.
Of course we all like color TFT displays. So the answer seems obvious, but may be not!
Starting from software v013, we are trying to separate the process of weather data processing from the process of data display. And why? To keep the costs low, our system uses an Arduino Nano as main processor, and it have a limited amount of RAM, many of it used by the routines or libraries to drive the TFT display, leaving us without RAM space, to further development of more important functionalities. This is the main reason why we have developed the WeatherDuino Pro2 Wireless Display system, freeing the main RX unit for its principal role: process your weather data, and pass them to Cumulus (if you use Cumulus, please donate to autor, he deserves).
As I said many times, I take backwards compatibility very seriously, but at some point in the future, near or not, new planned RX functionalities will require disabling the actual 1.8" TFT display, and use only the LCD display. If you already have an TFT display, of course you can continue using it, but you can't take vantage of some new functionalities that will be added in future software releases. Anyway, connecting an LCD display is very easy... the connector is already there.
If you are starting now, it's up to you decide the better way...
Maybe seems suspect, being I to give a suggestion, but its an honest one!
Leave the color displays, for the WeatherDuino Pro 2 Wireless Display units.
