Arduino Uno Rev3 out of memory space

Projects Programming

I'm running out of memory with my sketch and had to deactivate a few parts of code.
This is the actual occupancy :
Lo sketch usa 31.884 byte (98%) dello spazio disponibile per i programmi. Il massimo è 32.256 byte.
Le variabili globali usano 1.355 byte (66%) di memoria dinamica, lasciando altri 693 byte liberi per le variabili locali. Il massimo è 2.048 byte.

When i uncomment this i run out of space going to 103% usage :

dtostrf(temp_dht, 5, 2, temp_int_attuale);

Any suggestions?

marcomaroso:

Le variabili globali usano 1.355 byte (66%)

As it looks you are running out of "flash memory" (used for program code) first, but RAM is only used 66%.

How does that come from?

Using many heavy-weight libraries like Ethernet and SD and possibly some more third-party libraries?

In that case you'd possibly have to hand-optimize your code.
Or use less third-party libraries.
