dynamic memory iusse

hi,

when compile sketch under ide 1.6.1 kind of warning compiler.
it tells me global variables using 1.741 byte (85%) of dynamic memory, leaving 307 byte local variables.
then in red tells me there stability problem.

looking @ code there not many global variables. take look:

code: [select]


#define topclo      30000     // tempo apertura/chiusure in millisecondi
#define items       30           // numero di misure nella media
#define scricchero  1000   // movimento dx in millisecondi


maxbotix rangesensorpw(sonarpw_pin, maxbotix::pw, maxbotix::lv);
maxbotix rangesensor2pw(sonarpw2_pin, maxbotix::pw, maxbotix::lv);
boolean is_moving=false;
boolean is_open=false;
boolean is_sonar_active=false;
boolean is_panic=false;
boolean inseguimento=false;
boolean logging=false;
boolean spostamento=false;
int distsoglia = 67;
int dist[items];


there no other global variable.
i tried decreasing number of items gain few free bytes
i tried use 1 maxbotix variable again tiny gain in free bytes

where waste memory then?

thank all

mic

libraries? hard tell code snippet.

add:

also when print constant text without using f() macro, copied ram @ startup.
