Hallo zusammen,

bin noch nicht selber zu ausprobieren des DS1307 gekommen, aber ich habe eine grundlegende Frage. In Bascom gibt es ja die Standartroutine DS1307.bas und die ds1307clock.lib.
Muss im code wie im Beispiel unten Abschnitt `called from ds1307 überhaupt im Code sein oder würde er bei compilen das automatisch aus der .lib so holen?

Code:
'-------------------------------------------------------------------------------
'                           DS1307.BAS
' shows how to use the ds1307 clock on the 2313 futurlec board
' it also shows the CONFIG CLOCK=USER option
'-------------------------------------------------------------------------------
$regfile = "2313def.dat"
$crystal = 8000000
$baud = 19200
$lib "mcsbyte.lbx"                                          ' for smaller code
$lib "ds1307clock.lib"                                      ' modified lib
$framesize = 16
$hwstack = 24
$swstack = 16


'configure the scl and sda pins
Config Sda = Portd.6
Config Scl = Portd.5

'address of ds1307
Const Ds1307w = &HD0                                        ' Addresses of Ds1307 clock
Const Ds1307r = &HD1

Config Clock = User                                         ' this will dim the bytes automatic
'dim other needed variables
Dim Weekday As Byte

Print "DS1307"
Waitms 100
' assigning the time will call the SetTime routine
Time$ = "23:58:59"                                          ' to watch the day changing value
Date$ = "11-13-02"                                          ' 13 november 2002
Do
  Print "Date Time : " ; Date$ ; " " ; Time$
  Waitms 500
Loop

End

'Muss das hier unbedingt im sein oder ist das Beispiel aus der LIB???????
