Hello,
I'm trying to figure out what's wrong with this code, I have this
STATIC method in PanelPellet class
CNapisy::TTextId PanelPellet::getStateString(uint16_t state)
{
switch (state)
{
case ST_PRACA_RECZNA:
return CNapisy::IDT_TEXT_PRACA_RECZNA;
break;
case ST_OFF:
return CNapisy::IDT_TEXT_WYLACZONY;
break;
case ST_PALENIE_RECZNE:
case ST_PALENIE_RECZNE_PRZEDMUCH_PRACA:
case ST_PALENIE_RECZNE_PRZEDMUCH_PRZERWA:
return CNapisy::IDT_TEXT_PALENIE_RECZNE;
break;
case ST_PODSYP:
case ST_OPOZNIENIEROZPALANIA:
case ST_PRZERWAROZPALANIA:
case ST_PRACAROZPALANIA:
return CNapisy::IDT_TEXT_ROZPALANIE;
break;
case ST_PRACA:
case ST_PRZERWA:
return CNapisy::IDT_TEXT_PRACA;
break;
case ST_PRACAMODULACJI:
case ST_PRZERWAMODULACJI:
return CNapisy::IDT_TEXT_PRACA_MOD;
break;
case ST_PRACAPRZEJSCIA:
case ST_PRZERWAPRZEJSCIA:
return CNapisy::IDT_TEXT_FAZA_PRZEJSCIA;
break;
case ST_PRZERWAPODTRZYMANIA:
case ST_PRACAPODTRZYMANIA:
case ST_OPOZPODAJNIKA:
case ST_OPOZNADMUCHU:
return CNapisy::IDT_TEXT_PODTRZYMANIE;
break;
case ST_WYLACZANIE:
case ST_WYLACZANIE_DOSYP_CZEKAJ:
case ST_WYLACZANIE_DOSYP:
case ST_WYLACZANIE_RUSZTAWSTEPNIE:
case ST_WYLACZANIE_2NDPHASE:
case ST_WYLACZANIE_DOSYP2:
case ST_RUSZTAOCZYSC:
return CNapisy::IDT_TEXT_WYGASZANIE;
break;
default:
return CNapisy::IDT_PONIEDZIALEK_SHORT;
break;
}
}
"state" switch parameter is simple uint definition for example
#define ST_SOMETHING 10
nothing special, and CNapisy::TTextId is enumeration type of CNapisy class.
Problem:
When I use this method in my program then according to avr-size, RAM
memory usage jumps by 168 bytes! Why? I thought this should not take
any RAM until execution, am I right?
or maybe I misinterpreting avr-size output, Can someone explain please?
before:
AVR Memory Usage
----------------
Device: atmega128
Program: 73812 bytes (56.3% Full)
(.text + .data + .bootloader)
Data: 3209 bytes (78.3% Full)
(.data + .bss + .noinit)
EEPROM: 197 bytes (4.8% Full)
(.eeprom)
after:
AVR Memory Usage
----------------
Device: atmega128
Program: 74100 bytes (56.5% Full)
(.text + .data + .bootloader)
Data: 3377 bytes (82.4% Full)
(.data + .bss + .noinit)
EEPROM: 197 bytes (4.8% Full)
(.eeprom)
I know it's not much info here, but i don't know where to start
diagnosing, and I can't provide whole project code. I'll try to
provide as much details as possible, when needed.
Cheers.
