08/27/2008 Gathering up patches for a v3.6.0 release. Changes Include:
- Releasing new version with these changes:
- Updated to the .spec file from Fedora9
- DS2490 now suppresses the 'Found usb ...' output
- Support for compiling under DARWIN
- Current reading added to DS2438
- DS28EA00 support added
- Tabbed output of 0.00 on CRC errors with log type -o2 or -o3
- New manpage from Debian digitemp maintainer
01/01/2007 Released v3.5.0
12/26/2006 Adding DS1923 Hygrosens Logger support from Tomasz Nowak
Moved all of the history to ChangeLog
12/25/2006 Added Cygwin support
Fixing ambiguous error messages (eg. blank config file
or blank serial device).
06/25/2005 Logging output for DS2438 is not consistent with the other
outputs. When -o2 and -o3 are used the temperatures for the
DS2438 devices are output.
The -H option can still be used to customize the DS2438
output when not using the -o options.
02/03/2004 Broke DS9097 support with my owWriteBytePower() return code
check in digitemp.c in v3.3.1, so I applied the new DS9097
performance patch from Erik Rigtorp and changed owLevel in
the ds9097 code to return the value called with to fake out
the higher level code.
Added FREEBSD to the typedef section of ownet.h, maybe this
will fix some of those problems.
02/01/2004 Fixed DS2490 USB adapter support. Fixed Makefile so that it
doesn't need to be edited for USB support.
01/25/2004 A user reported a bug in the humidity temperature, it
wasn't converting negative temperatures correctly.
I also see a potential problem with the DS18B20 and DS1822
which use a short int type and depend on it being 16 bits
so that the sign comes out correct. But can we count on a
short int always being 16 bits? I need to look into it.
01/10/2004 I'm trying to wrap up all the patches I've received int a new
release v3.3.0 with humidity and DS2438 support. Added code
from Eric Wilde to do humidity calculations for the
AAG TAI-8540 humidity sensor.
Adding patches for OpenBSD from Mns Nilsson.
Changing the binary names that are generated to differentiate
between DS9097, DS9097U and DS2490 (usb) adapter support.
The USB support still doesn't work right. It searches the LAN
ok, but needs to be root to do so, and doesn't read properly.
I'll deal with it in the next release I guess.
Added lockfiles. This requires either setting the binary to
group lock (chmod g+s;chown .lock digitemp_*) or adding the
user who will be running it to the lock group.
11/29/2003 Trying to get a first pass at DS2438 (A/D & Battery monitor)
support up and running.
Found a bug, init wouldn't record counters found on branches
of a hub.
10/27/2003 Added patch from Sven Geggus to allow -n0 to make it run
in an infinite loop. Need to check for exit conditions
and clean up logfile, serial port, etc. in a nice manner.
08/13/2003 Adding DS2490 USB to 1-wire adapter support. Bumping the
version number to 3.3.0 without a release of 3.2.1
06/14/2003 Made change to hub search from Jess Roncero, it wouldn't
work right if run with -q (a owFirst was inside the
quiet check). Also adding the manpage created by Jes.
Version changed to 3.2.1
05/24/2003 Adding a banner that reports what library the binary was
compiled for (DS9097 or DS9097U).
Adjusted the makefile a bit, change the dist to be one of
dist-9097 or dist-9097u to build for the right target.
05/23/2003 Adding kludges for USB to Serial adapter. Added a loop of
10 tries to the DS2480Detect routine. Added DEBUG_USERIAL
compile time wrappers for diagnostic information about the
ReadCOM routine. Part of the key to this is the delay used
in ReadCOM, its just too short for use with the USB to
serial adapter. I've changed it to 1 second + 10-15mS --
I'm not sure that the global_msec is really needed with the
longer timeout time, its a fail-safe anyway; the character
ought to come back a long time before the timeout.
Changed version to v3.2.0
02/14/2003 Adding logging of read values. Need to change the way it
handles building the output string.
It works, but the counter really needs its own format
string. Kinda hard to automatically integrate it into the
current temperature oriented format string.
02/12/2003 Adding more code... Needs more work, the family code may
be buried in the coupler linked list. I may need to move the
decision as to how to read it to after it finds the coupler
and turns it on.
Change read_temp to read_sensor. device selection is common
to all devices, then switch based on the serial number
finally selected (saved as it is selected).
02/06/2003 Changed version number to v3.1.0
Adding support for counters
Happy 92nd Birthday to Ronald Reagan!
01/10/2003 Finally, humidity is working, thanks in large part to work
by Eric Wilde. Need to add logging of DS2438. I think it
will be hard-coded, if it needs to be in another format
it can be parsed with perl or python or whatever.
Fixed a bug that wasn't allowing %% to be embedded in the
format specifier.
Adding lockfile support using the lockdev library under
Linux. Wrapping it in LINUX checks until other systems
indicate that they can use it.
Lockfiles are working, but - the binary has to be sgid to
the lock group so that it can access /var/lock, adding
the user to the lock group would also accomplish this.
01/08/2003 Still trying to get DS2438 and Humidity support working
Also changing strcpy to strncpy, dunno why they weren't
already using it.
01/04/2003 Adding DS2438 based humidity support from Eric Wilde.
11/21/2002 Changed sleep method to use less CPU cycles, thanks to
peter enderborg for pointing it out.
11/19/2002 Reviewing massive changes from Erik Rigtorp, he has added a
userial compatible version of the passive adapter code. I am
creating a new Makefile that will work for all systems and
allow selection of the adapter at build time.
Thanks for this version go to Erik Rigtorp for adding the
userial compatible passive code. His webpage can be found
at http://erkki.g0ds.org/
Thanks also go out to Kevin Pedigo for his help in getting
the new Makefile up and running. Kevin is the current
President of KPLUG (www.kplug.org/~kevinp)
Improved the sleep method when reading sensors multiple
times so that it doesn't use 100 CPU while waiting. Thanks
to peter enderborg for pointing this out.
Changed version # to v3.0.0
08/21/2002 Small bug with -i crept in, it wants another command to be
present, it won't just initialize.
08/18/2002 Added %N token to allow the time in seconds since Epoch to
be selected in the output.
Added module for NetSaint/Nagios to perl directory, it is
named check_digitemp.pl
Added a MySQL logging script to perl directory, it is named
digitemp_mysql.pl
Added check for serial port permissions and nice error
output if the user doesn't have +rw on the selected port.
Removed limitation on -i being the only command. It can be
combined with other commands again.
Changed to v2.6
08/16/2002 Adding %N token to output seconds since Epoch, which is
masked by my use of %s for the sensor number. I don't want
to remove %s, because that would break old code. So %N
now maps to %s in the strftime format.
The check for commands is too strict, it isn't allowing
-i to be combined with any of the other commands.
Added permission checking on the serial device with a clean
exit if the user doesn't have access to the serial device.
06/23/2002 Releasing new version today. Really! Making -q turn off
the extra output I added for initializing the 1-wire lan.
06/08/2002 Adding patches from John. exit() codes are now #defines
and .digitemprc now outputs the serial numbers as hex
instead of decimal. But maintains backwards compatibility
until a new .digitemprc is written.
Output format string now includes an option to output the
Sensor's serial number in hex (%R).
06/08/2002 Made changes suggested by John Stoffel. Consisting mostly of
code reorganizations.
The one new feature is the %R format specifier for the log
output string which inserts the hex serial number of the
sensor into the output.
We changed the way command line arguments are processed,
so getopt is only called once, and added a check to make
sure only 1 of the action commands is specified and complain
otherwise.
Changed to v2.5
05/11/2002 Adding more changes from John Stoffel
05/08/2002 Integrating changes for Solaris, AIX, FreeBSD from John
Stoffel. Changes to getopt initial settings, Makefile
and include files.
05/06/2002 Adding changes and fixes from DT v2.5 for Windows.
Family code for DS1822 was wrong, it is really 0x22
Lots of changes to the read_temp routine, added a better
scratchpad dump routine (previous one only worked for
the DS1820).
Quite a bit needs to be changed, I have switched to using
a structure to store the sensor and coupler lists. I
updated the core temperature read routine, the lan walk
and device search routines. Reading when using a hub
is now faster when reading multiple devices on the
same hub segment.
01/15/2002 Cleaning up, preparing for release
01/15/2002 Added support for DS2409 one-wire couplers like those used in
Simon Atkin's hub. www.simat.enta.net
Converted to Dallas Semi's userial v3.00 one-wire library.
Version changed to v2.3
Added a -w command to walk the entire one-wire LAN and show all
device serial numbers with a descriptive family type.
Thanks to Ted Frohling for the loan of the one-wire Hub.
01/14/2002 Adding support for reading sensors on DS2409 couplers.
01/13/2002 Walking the tree now works -- after changing the swt1f.c
routine to use the Smart-On Main command while searching
for devices (otherwise it only finds the first).
Adding support for Coupler to the main program.
Init now works, writing .digitemprc now works.
Read .digitemprc appears to work.
Need to add reading of specified sensors and of all
sensors.
01/12/2002 Adding a diagnostic walk of the attached network, working
on DS2409 MicroLAN Coupler support.
Added release1WireNet calls before all exit calls.
Switching to the userial library v3.0.0, I seem to have
run into a problem with the old library and I cannot read
either of my DS9097U adapters with v2.2 digitemp code.
05/26/2001 The 18B20 and 1822 patch didn't work. It was reading the
wrong scratchpad registers. (2,1 instead of 1,0).
Changed version to v2.2
03/16/2001 Integrating the AIX patch from Ewan Leith
<ejl@man.fraser-williams.com>
It amounts to return value checking on getopt and changes
in the wirelnk.c file.
Adding DS1822 and DS18B20 changes from Roland Roberts
<roland@astrofoto.org>
03/16/2001 Integrated the AIX changes
Integrated the DS1822 and DS18B20 patch
Added the patch for DS1822 and DS18B20 support.
03/13/2001 Version 2.1 release
Added detection of a temperature glitch in the DS1820
Added detection of the DS18S20's 85 degree C error state
Added output of error conditions to stderr
Bad reads will now insert zeros instead of skipping the sensor
If a read fails it is retried 3 times before giving up on that
sensor. The remainder of the sensors are still attempted.
Added a command line option (-c) to allow the configuration
file to be specified.
Added a couple more scripts to the rrdb directory.
03/05/2001 Adding a command line option to specify the configuration
file to use. -c config_file will override the default of
.digitemprc
02/17/2001 If there is an error with strong pullup on/off it shouldn't
abort the conversion! Just log an error to stderr.
01/31/2001 Added a dummy temperature output when a sensor cannot be
read. It outputs a 0 so that scripts like my grapher
don't get confused and log the wrong sensor in the wrong
place.
An error message is also output to stderr.
01/29/2001 Oops. It seems that I missed the line in the DS1820
datasheet that says Vdd needs to be tied to GND for
Parasite power to work correctly.
Various curses come to mind.
The DS1820 works better than the DS18S20 with Vdd floating
but this probably explains the infrequent glitches I
saw before adding the DS18S20s.
01/15/2001 Still getting glitches.
Adding a reset and delay before retry
01/14/2001 Changed Version number to 2.1
I now have 2 DS18S20 sensors which supposedly fix the
Temperature accuracy problems of the DS1820 (see the
ds1820-report.pdf from Dallas). But now I get a huge
number of glitches in the DS18S20's readings.
The DS18S20 has an error condition, but it is +85C and
the glitches I am seeing are because DigiTemp doesn't
output anything at all for the DS18S20's reading.
Adding a check for the DS18S20's error condition:
LSB = 0xAA
MSB = 0x00
COUNT_REMAIN = 0x0C
COUNT_PER_C = 0x10
If this error case is encountered, the reading should be
repeated. If it comes up again, use it.
There is also a glitch possible in the DS1820 that exhibits
itself by COUNT_PER_C - COUNT_REMAIN = 1, this should be
checked for, and the reading repeated and the next result
used.
The problem with no reading from the device seems to
happen when MLanAccess is called. There is no good way to
tell what the problem is, so I will change the code to
try 3 times before failing. Changes are in read_temp.
01/04/2000 Changing the default read timeout to 1000mS. I had problems
with it set to 500mS and a 30' sensor wire (the reading
was low by about 10 degrees).
01/04/2000 Version 2.0 release
Adding support for the DS9097-U adapter for the Linux
version. The Solaris version will need changes to be able
to support the DS9097-U.
Changed license to GNU General Public License v2.0
Added the -q option to make the banner disappear.
01/01/2000 Well, no release last year. Adding -q to make the banner
dissapear for batchfiles that want to get the output
directly.
12/28/1999 Changed Version number to 2.0
Adding GNU public license
Changing this code to use the DS9097-U adapter
06/03/1999 Finishing this thing up.
06/02/1999 Use 2 logging routines, log_time to log a single line
per sensor with optional time data and log_str to log
a single line for multiple sensors with elapsed time at
the beginning of the line.
05/29/1999 Added 2 new init file tags, LOG_FORMAT and LOG_TYPE
New formatting works, need to clean up the logic now.
05/27/1999 Adding user specified format string. To use it, first
parse out the digitemp specific stuff and create a new
string to feed into strftime, with the sensor, temperature
already set.
05/24/1999 Adding a output specifier string, this will allow users
to configure the output to look however they want it to.
The format string uses strftime tokens plus 3 special
ones for digitemp - %s for sensor #, %C for centigrade,
%F for fahrenheit
05/23/1999 Adding Solaris support via -DSOLARIS define
Fixing the time problems once and for all, using localtime
in the log_line routine. The user should have TZ set
correctly for their timezone. This has been tested
and works correctly.
Changed version number to v1.3
05/23/1999 Adding Solaris changes, donated by a user.
Removing libc5 binaries, I no longer have a libc5 system
Fixing the time problems with logging
01/14/1999 A user in Sweden (and another in Finland) discovered a
long standing bug. In do_temp I should have been using
0x100 instead of 0xFF for the subtraction. This caused
temperatures below 0 degrees C to jump up 1 degree as
it decreased. This is fixed.
Changed version number to v1.2
10/20/1998 Adding new features from DOS version to keep things
consistent. Removing the debug command, not used anyway.
Added a free() to error condition edit from read_rcfile()
Set some cases of freeing to = NULL, also freed the rom
list before doing a search rom (searchROM checks too, but
this is the right place for it).
08/31/1998 Adding a check for family 0x10 so that we can read DS1820s
while they are on a network that includes other 1-wire
devices.
Fixed a problem with freeing uninitialized rom_list when
starting a SearchROM. Not sure why this never appeared
before.
03/06/1998 Adding a -d debug level to help figure out why this thing
is no longer working.
03/13/1997 Error in CRC calculation. Wrong # of bytes.
Error with 3 sensors. Sometimes doesn't store correct ROM
data to .digitemprc -- need to malloc more memory dummy!
03/08/1997 Adding user defined timeouts for failure and for the
read delay.
01/24/1997 Changed over to correct baud rate and 6 bits @ 115.2k
ROM search function is now working. All low level code
is functioning except for Alarm Search. Starting to move
into a seperate object file with API for users to write
their own code with.
01/22/97 Working on ROM search routine, double cannot handle a full
64 bits for some reason, converting to 64 byte array for
each bit.
01/19/1997 Rewriting for new interface. This programs handles all the
low level communications with the temperature sensor using
the 115200k serial adapter.
01/02/1996 Rewriting this code to be more user friendly
