because the lib is included at a different point you need to change :
Rcall _1wire_set_pin ; some common cod
into
call _1wire_set_pin ; some common cod

that should solve it.

@kimmi
if the lib is working, please send it so i can include it , it might be interesting for other users.

Hi Mark,

I have sent the lib now

Looks like there might be a problem with the lib in combination with AVR-DOS

This row in my program:
Open FileName For append As #Ffh
Generates a compile time error: Backward Jump out of range in _1wire_search_next
If I rem that row, the program compiles.

You can see the problem with this sample program:

$regfile = "m128def.DAT"
$baud = 115200
$baud1 = 115200
$crystal = 14745600
$hwstack = 128 ' hardware stack
$swstack = 128 ' SW stack
$framesize = 128 ' frame space
Set Mcucsr.jtd 'Disable JTAG
Set Mcucsr.jtd

$lib "M128-1wire-PortF_3.LBX"

config 1wire = pinf.6 , extended = 1

$include "config_mmcsd_hc.bas"
$include "CONFIG_AVR-DOS.bas"

Dim Ffh As Byte , Filename as string * 12
Filename = "test.txt"

Ffh = Freefile()
Open FileName For append As #ffh 'PROBLEM

close #ffh

1wverify TempSensorID(1) 'PROBLEM

This will generate a compile time error unless you rem either the Open Filename... row or the 1wverify... row

the solution was to add the other 1wire routines as well.
I will include the lib with the next update for others that might want to use it.

and what i forgot : extend=1 should be removed. extended is only for ports with an address of &H100 or higher. Xmega excluded since that is handled different anyway.
and also : when you use the special lib, you can not use 1wire on another port. this special lib is only for m128 portF.
