New Features and Fixed Problems in V1.6.615 (13-MAY-2018)

• Updated for CANlib SDK v5.23.
• Getting version numbers should now be done with dllversion(), which will return canlib.BetaVersionNumber if the dll is marked as Beta. Also added canlib.prodversion() to return the CANlib product version number.
• canlib.device:
  • New canlib.device.Device class (available as canlib.Device) that is a simpler version of kvDevice. canlib.device.Device objects can be defined using an EAN and serial number, or a connected device can be searched for using canlib.device.Device.find. These objects do not require the device to stay connected, and can be used to later create most other canlib objects, e.g. canlib.canlib.Channel, canlib.kvmlib.Memorator, etc.
  • New canlib.device.connected_devices which returns an iterator of canlib.device.Device objects, one for each device currently connected.
• canlib.ean:
  • canlib.ean.EAN objects can be tested for equality, both with other canlib.ean.EAN objects and with strings.
  • Added CanNotFound exception.
  • canlib.ean.EAN objects can now be directly instantiated from string, i.e. ean = canlib.EAN(ean_string) instead of ean = canlib.EAN.from_string(ean_string).
  • canlib.ean.EAN objects can be converted back into any of the representations that can be used to create them. See the documentation of canlib.ean.EAN for more info.
  • canlib.ean.EAN objects can be indexed and iterated upon, yielding the digits as ints.
• canlib.canlib:
  • canlib.canlib.EnvVar object raises EnvvarNameError when given an illegal name, instead of AssertionError.
  • canlib.canlib.openChannel can now set the bitrate of the channel opened.
  • canlib.canlib.Channel objects automatically close their handles when garbage collected
  • canlib.canlib.Channel has new methods canlib.canlib.Channel.scriptRequestText and canlib.canlib.Channel.scriptGetText to get text printed with printf() by a script. This text is returned as a canlib.canlib.ScriptText object.
• canlib.kvamemolibxml:
  • A new, object oriented way of dealing with kvamemolibxml using canlib.kvamemolibxml.Configuration objects.
• canlib.kvmlib:
  • Improved object model
    • New canlib.kvmlib.openDevice function that returns a canlib.kvmlib.Memorator object representing a connected Memorator device. See the documentation of canlib.kvmlib.Memorator for instructions on how to use this new class to more easily interface with your Memorators.
    • New canlib.kvmlib.openKmf function for opening .KMF files that returns a canlib.kvmlib.Kmf object that is similar to canlib.kvmlib.Memorator. See the docstring of canlib.kvmlib.Kmf for more information.
• canlib.linlib:
  • Getting version number with canlib.linlib.dllversion (requires CANlib SDK v5.23 or newer).
  • Explicit canlib.linlib.Channel.close function for forcing a linlib channel's internal handle to be closed.
• canlib.canlib:
  • Added support for accessing information within compiled t program (.txe) files.
    • Added wrapper function for kvScriptTxeGetData.
    • Added compiled t program (.txe) interface class canlib.canlib.Txe.
• canlib.kvadblib:
  • enums now returns non-empty dictionary in attribute definition returned from EnumDefinition.definition

New Features and Fixed Problems in V1.5.525 (12-FEB-2018)

• Updated for CANlib SDK v5.22.
• Added support for LIN bus API (LINlib)
• Added support for Database API (kvaDbLib) Needs version v5.22 of CANlib SDK to get supported dll.

Restructuring of code in order to make the API simpler and the code base more maintainable have resulted in the following changes (old style is deprecated, shown in details while running Python with the -Wd argument):

• canlib.kvMessage has been renamed canlib.Frame
  • canlib.Frame objects are now accepted and returned when writing and reading channels.
  • The new canlib.kvadblib module uses these canlib.Frame objects heavily.
• canlib.canlib:
  • Added wrapper functions for canReadStatus and canRequestChipStatus
  • Deprecated use of canlib.canlib.canlib() objects; all methods have been moved to the module.
    • See the docstring of canlib.canlib.CANLib for more information
  • Simplified the names of the channel-classes (old names are deprecated):
    • The channel class is now canlib.canlib.Channel, instead of canlib.canChannel.
    • canlib.canlib.ChannelData_Channel_Flags is now canlib.canlib.ChannelFlags
    • canlib.canlib.ChannelData_Channel_Flags_bits is now canlib.canlib.ChannelFlagBits
  • canlib.canlib.Channel now uses canlib.Frame objects for reading and writing.
    • canlib.Channel.read now returns a canlib.Frame object instead of a tuple. However, canlib.Frame objects are largely compatible with tuples.
    • canlib.Channel.write takes a single argument, a canlib.Frame object. The previous call signature has been taken over by canlib.Channel.write_raw.
    • Likewise for canlib.Channel.writeWait and its new friend canlib.Channel.writeWait_raw.
  • The class canlib.canlib.canVersion has been removed, and canlib.canlib.getVersion now returns a canlib.VersionNumber. The new class still supports conversion to string and accessing .major and .minor attributes.
• canlib.kvmlib:
  • Added wrapper functions for kvmKmeReadEvent.
  • Corrected encoding for Python 3 in kmeOpenFile().
  • Deprecated names for several classes to make them more logical and more pythonic:
    • canlib.kvmlib.memoMsg is now canlib.kvmlib.LogEvent
    • canlib.kvmlib.logMsg is now canlib.kvmlib.MessageEvent
    • canlib.kvmlib.rtcMsg is now canlib.kvmlib.RTCEvent
    • canlib.kvmlib.trigMsg is now canlib.kvmlib.TriggerEvent
    • canlib.kvmlib.verMsg is now canlib.kvmlib.VersionEvent
  • The class canlib.kvmlib.kvmVersion has been removed, and canlib.kvmlib.KvmLib.getVersion now returns a canlib.VersionNumber. The new class still supports conversion to string and accessing .major, .minor, and .build attributes.
• canlib.kvlclib:
  • Added method canlib.kvlclib.addDatabaseFile and helper object canlib.kvlclib.ChannelMask.
  • The canlib.kvlclib.KvlcLib object has been deprecated.
    • All functions that relate to converters have been moved to the more appropriately named canlib.kvlclib.Converter.
      • Some of these functions have been renamed:
        • IsOutputFilenameNew, IsOverrunActive, and IsDataTruncated have all had their initial "i" lower-cased, as the upper case "I" was an error.
        • getPropertyDefault and isPropertySupported are no longer available on the Converter object, they must be accessed via the format attribute:

          converter.format.getPropertyDefault(...)

    • canlib.kvlclib.WriterFormat.getFirstWriterFormat and canlib.kvlclib.WriterFormat.getNextWriterFormat now returns a kvlclib.FileFormat object (which is based on the IntEnum class).
    • Other functions have been moved to the canlib.kvlclib module.
    • deleteConverter is no longer supported. Instead, converters are automatically deleted when garbage collected. If their contents must be flushed to file, see the new canlib.kvlclib.Converter.flush method.
  • The class canlib.kvlclib.KvlcVersion has been removed, and canlib.kvmlib.kvlclib.getVersion now returns a canlib.VersionNumber. The new class still supports conversion to string and accessing .major, .minor, and .build attributes.
• canlib.kvrlib:
  • The canlib.kvrlib.KvrLib object has been deprecated; all methods have been moved to the module.
  • canlib.kvrlib.getVersion no longer returns a canlib.kvrlib.kvrVersion but a canlib.VersionNumber. The return value still supports conversion to string and accessing .major and .minor attributes.
• canlib.kvamemolibxml:
  • Renamed from canlib.KvaMemoLibXml, however trying to import the old name will just import the new one instead.
  • Deprecated the use of canlib.kvamemolibxml.KvaMemoLib objects, all methods have been moved to the canlib.kvamemolibxml module itself.
  • Breaking change: Moved values that were incorrectly defined as constants into enums. In most cases this should not have any impact, as all the values are internal error codes and are turned into Python exceptions. But if you nonetheless use the kvamemolibxml status values directly, you'll need to change your code as follows:
    • KvaXmlStatusERR_XXX_XXX is now Error.XXX_XXX.
    • KvaXmlValidationStatusERR_XXX_XXX is now ValidationError.XXX_XXX
    • KvaXmlValidationStatusWARN is now ValidationWarning.XXX_XXX.
    • KvaXmlStatusFail is now Error.FAIL (Changed to be consistent with other KvaXmlStatus errors). The same is true for ValidationError.FAIL.
    • KvaXmlStatusOK and KvaXmlValidationStatusOK are still treated as if they are constants, as they are not error statuses.
  • canlib.kvamemolibxml.getVersion no longer returns a string but a canlib.VersionNumber. The return value still supports conversion to string.
• Exceptions:
  • Exceptions throughout the package have been standardised, and now all inherit from canlib.exceptions.CanlibException.
  • The canERR attribute that some exceptions had has been deprecated in favour of a status attribute. Furthermore, all canlib exceptions now have this attribute; the status code that was returned from a C call that triggered the specific exception.
