Hi,

First of all excuse my low english level. Something extrange happend to me....When I run the follow code (I'm using an AP16)

void CONVERT_DATA(void)
{
TEMPORAL1=MSGRECEIVED[17];
TEMPORAL1=TEMPORAL1-48;
LATITUDE=TEMPORAL1*10;
TEMPORAL1=MSGRECEIVED[18];
TEMPORAL1=TEMPORAL1-48;
LATITUDE=LATITUDE+TEMPORAL1;

TEMPORAL1=MSGRECEIVED[19];
TEMPORAL1=TEMPORAL1-48;
MIN=TEMPORAL1*100000;
TEMPORAL1=MSGRECEIVED[20];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*10000;

TEMPORAL1=MSGRECEIVED[22];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*1000;
TEMPORAL1=MSGRECEIVED[23];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*100;
TEMPORAL1=MSGRECEIVED[24];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*10;
TEMPORAL1=MSGRECEIVED[25];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1;

MIN=MIN/600000;
LATITUDE=LATITUDE+MIN;

TEMPORAL1=MSGRECEIVED[29];
TEMPORAL1=TEMPORAL1-48;
LONGITUDE=TEMPORAL1*100;
TEMPORAL1=MSGRECEIVED[30];
TEMPORAL1=TEMPORAL1-48;
LONGITUDE=LONGITUDE+TEMPORAL1*10;
TEMPORAL1=MSGRECEIVED[31];
TEMPORAL1=TEMPORAL1-48;
LONGITUDE=LONGITUDE+TEMPORAL1;

TEMPORAL1=MSGRECEIVED[32];
TEMPORAL1=TEMPORAL1-48;
MIN=TEMPORAL1*100000;
TEMPORAL1=MSGRECEIVED[33];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*10000;

TEMPORAL1=MSGRECEIVED[35];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*1000;
TEMPORAL1=MSGRECEIVED[36];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*100;
TEMPORAL1=MSGRECEIVED[37];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1*10;
TEMPORAL1=MSGRECEIVED[38];
TEMPORAL1=TEMPORAL1-48;
MIN=MIN+TEMPORAL1;

MIN=MIN/600000;
LONGITUDE=LONGITUDE+MIN;

TEMPORAL1=MSGRECEIVED[44];
TEMPORAL1=TEMPORAL1-48;
SATELITES=TEMPORAL1*10;
TEMPORAL1=MSGRECEIVED[45];
TEMPORAL1=TEMPORAL1-48;
SATELITES=SATELITES+TEMPORAL1;
}

The values of MSGRECEIVED changes and I don't understand why it happen if I don't assing this array in this funtion I only read it. If you can help me I'll really apreciate it.

Regards,

Jonathan

Variables changing unexpectedly is almost always caused by stack overflow. Try to make the stack larger and see if this solves the problem.

Thankyou Lundin I made the stack larger and it solved the problem.
