Det här kommer ofta upp när jag försöker ta in färdiga kodexempel.
Är det någon som har en aning om vad som är fel, och vad man kan göra åt det?
In function 'void loop()':
error: 'class DateTime' has no member named 'get'
Serial.println(now.get());
Har försökt leta i dom h-filer som blir includade, men hittar inget get, hmm...
Återkommande fel i Arduino-koden. (FIXAT igen)

Re: Återkommande fel i Arduino-koden.
Säker på att du ska använda "get"?
Många funktioner är definierat så att de har en "get" & en "put" men då menas ibland att "get" betyder att man hämtar värdet ("X = now()") och "put" att ett värde ges till funktionen ("now(X)" eller "now() = X")

Re: Återkommande fel i Arduino-koden.
Icecap, det är inte jag som skrivit koden, dom är färdiga exempel, bara att öppna.
Här är hela koden.
När man kompilerar (Verify) så kommer följande upp i nederkant på fönstret.

error: 'class DateTime' has no member named 'get'

Re: Återkommande fel i Arduino-koden.
Gissar att det är C.
I så fall
Du skapar en variabel med namn "now" av typen DateTime, vilket förmodligen är en struct eller nått liknande.
Ett par rader längre ner, används now.get() vilket rimligtvis borde vara ett funktionsanrop.
Du får försöka hitta definitionen av DateTime, vilket sannolikt ligger i RTCLib.h (eller snarare troligen i RTCLib.c)

Re: Återkommande fel i Arduino-koden.
Har du installerat bibloteken som används eller bara öppnat exempelkoden?
Re: Återkommande fel i Arduino-koden.
Är det denna du använder? De har nog ändrat i "biblioteket" och glömt uppdatera exemplet. Om du byter "now.get()" till "now.secondstime()" tror jag det skall funka.

TomasL:
Har försökt att leta överallt, men hittar ingenting. Kan nog vara min kunskap som är begränsande.
Uttis:
Jepp, allt är inne, iaf så långt jag kan förstå, men...
Solly snigelen, men det kommer bara flera felmeddelanden nu.
Skulle vara bra att ha lite draghjälp från färdiga "moduler" när jag ska göra alarmklocka.
Jag har hittat bibliotek även för alarm, men det blir liknande fel även där.
Det är mest den där "get" som trasslar till det för mig.

The functions in this module provide interfaces for a program to access
data stored in program space (flash memory) of the device. In order to
use these functions, the target device must support either the \c LPM or
\c ELPM instructions.
\note These functions are an attempt to provide some compatibility with
header files that come with IAR C, to make porting applications between
different compilers easier. This is not 100% compatibility though (GCC
does not have full support for multiple address spaces yet).
\note If you are working with strings which are completely based in ram,
use the standard string functions described in \ref avr_string.
\note If possible, put your constant tables in the lower 64 KB and use
pgm_read_byte_near() or pgm_read_word_near() instead of
pgm_read_byte_far() or pgm_read_word_far() since it is more efficient that
way, and you can still use the upper 64K for executable code.
All functions that are suffixed with a \c _P \e require their
arguments to be in the lower 64 KB of the flash ROM, as they do
not use ELPM instructions. This is normally not a big concern as
the linker setup arranges any program space constants declared
using the macros from this header file so they are placed right after
the interrupt vectors, and in front of any executable code. However,
it can become a problem if there are too many of these constants, or
for bootloaders on devices with more than 64 KB of ROM.
<em>All these functions will not work in that situation.</em>

Re: Återkommande fel i Arduino-koden.
Allt är inte samlat på ett ställe, men det kan vara lämpligt att börja här:
http://arduino.cc/en/Main/Software
Sen finns det massa att läsa och hämta om man går till Arduinos Forum och Playground.
Jag startade med att hämta hem Arduino 0018 osv.
Man måste inte ha en Arduino för att se om det funkar.
Det går bra att compilera (Verify) ändå, utan att överföra till kortet.

Re: Återkommande fel i Arduino-koden.
Aha, OK. Det jag menade var att det ofta kan finns instruktioner tillsammans med
exempelkod om det är något speciellt man måste gör innan man "bygger" t.ex...

Re: Återkommande fel i Arduino-koden.
Och det finns ingen "get" i det lib. testa därför att ta bort ".get" i källkoden och se vad som händer.
Re: Återkommande fel i Arduino-koden.
Det är C++ dvs inte helt enkelt att börja med, snurrigt som fan rent ut sagt. I alla fall om man inte hållit på med objektorienterat tidigare.
Skulle nog rekommendera att hålla sig till C, det är lite mer raka puckar.
