Changes

0.11 (2024-05-03)

  • Frame exception updates; See below. The new_exceptions parameter has been removed from the Frame() constructor and the Frame.pack_len() method.
  • Method to control the power supply in the Lunatone DALI USB 30ma added to dali.driver.hid.tridonic [mbecker]
  • Improved support for colour-control devices (device type 8) [jktjkt]
  • Driver for Lunatine SCI RS232 [opieters]
  • Driver for AL-DALI-HAT [rijimuge]
  • Bug fixes to input device support [jktjkt]

Frame exception updates

The exceptions raised by dali.frame.Frame() and the Frame.pack_len() method are changing. In release versions <= 0.8, if you pass an invalid sequence to initialise a Frame a TypeError will be raised. In release 0.9 this changed to ValueError. If you pass an invalid length to pack_len(), currently a ValueError will be raised. In release 0.9 this changed to OverflowError.

To obtain the new behaviour when using release 0.8, pass new_exceptions=True to Frame() and pack_len(). In release 0.9, you can to continue to obtain the old behaviour by passing new_exceptions=False. In the release after that (provisionally "0.10"), passing any value for new_exceptions will issue a warning and in the release after that, the new_exceptions keyword argument will be removed.

The new behaviour makes the library more consistent with the exceptions raised by the native int.from_bytes() and int.to_bytes() methods.

0.10 (2022-10-24)

  • Python 3.6 is no longer supported.
  • Frame exception updates; see above. The old behaviour is no longer available and passing new_exceptions when calling the Frame() constructor or the Frame.pack_len() method will issue a warning.
  • The dali.address classes for gear and devices have been separated. dali.address.Short() has been split into dali.address.GearShort() and dali.address.DeviceShort(); similar changes have been made to Group(), Broadcast() and BroadcastUnaddressed(). The old names are still present and usable for gear, and there is no plan to remove them. [sl-wallace]
  • The 24-bit command support in dali.device.general has been improved: commands now have appropriate Response types. This code has now been tested against real hardware. [sl-wallace]
  • The memory subsystem now supports access to the memory banks of 24-bit control devices as well as 16-bit control gear. [sl-wallace]
  • 24-bit event messages are supported. [sl-wallace]
  • Support has been added for pushbutton devices (IEC 62386 part 301). [sl-wallace]
  • 24-bit frame support has been added to the async Tridonic driver. [sde1000]
  • A driver has been added for Lunatone LUBA serial DALI interfaces. [sl-wallace]
  • Support for colour devices (device type 8) has been added. [sl-wallace / Petr Ilgner]
  • Support for occupancy sensors (IEC 62386 part 303). [sl-wallace]
  • Support for light sensors (IEC 62386 part 304). [sl-wallace]

0.9 (2022-04-21)

  • Command._devicetype, Command.is_config and Command._response have been removed. (They were deprecated in release 0.7.)
  • Frame exception updates; see above. The new behaviour is now the default, and the old behaviour can be accessed by passing new_exceptions=False when calling the Frame() constructor and the Frame.pack_len() method.
  • Updated the Hasseb driver to use a more generally available HID library [dgomes]

0.8 (2021-12-02)

  • Memory bank subsystem: command sequences to access and interpret the contents of memory banks [ferdinandkeil, sde1000]
  • Frame exception updates; see above. The new behaviour can be accessed in this release by passing new_exceptions=True when calling the Frame() constructor and the Frame.pack_len() method.
  • Driver updates [jbaptperez, awahlig, rousveiga, rnixx]

0.7.1 (2020-09-02)

  • Remove unused problematic imports from dali.driver.hasseb [dgomes]

0.7 (2020-08-10)

  • Frame improvements: add pack_len() method and simplify str(BackwardFrame()) output
  • Add Response.raw_value attribute to Response objects to give access to the underlying BackwardFrame of the response (or None if no response was received)
  • Add NumericResponse and NumericResponseMask classes and make use of them where appropriate
  • Rename some Command class attributes, removing the initial _ to indicate that they are public. The API now supports Command.response, Command.devicetype, Command.uses_dtr{0,1,2}, Command.inputdev and Command.appctrl attributes.
  • Add support for "sequences" of commands that implement higher-level operations. Initial sequences include commisioning of control gear (discovering bus units and assigning short addresses), reading the list of device types, querying and setting group membership.
  • Remove the obsolete dali.bus module; all of the useful code from it is now implemented as sequences
  • 4–5× performance improvement of the command.from_frame() function
  • Remove support for Python 2
  • Some driver additions and changes [sde1000, hasseb, mhemeryck]

0.6 (2018-11-11)

  • Python 3 fix in async Tridonic driver [jjonek]
  • Updated Hasseb driver [dgomes]

0.5 (2017-05-15)

  • Move tests to dedicated package. [rnix]
  • Rename dali.device.Device._addressobj to dali.device.Device.address_obj since it is used as API in dali.command.Command. [rnix]
  • Move dali.device.Device class to dali.bus, dali.device module has been removed which conflicted with dali.device package. [rnix]
  • Add dali.exceptions module and move all DALI related exceptions to it. [rnix]
  • Move dali.interfaces to dali.drivers.daliserver. [rnix]
  • Update Package structure documentation. [rnix]

0.4 (2017-03-19)

  • PyPI support [dgomes]

0.3

  • Python 3 support [sde1000]

0.2

  • Introduce basic sync and async drivers. [rnix]
  • Basic implementation of LUNATONE Dali USB driver. [rnix]

0.1

  • Initial release. [sde1000]
