Modelica_DeviceDrivers v2.2.0

Updated package compatibility to Modelica 4.1.0.

Enhancements:

• Compile libMDDSpaceMouse.a with -fPIC (#388)
• Serial port: change number of data bits (#368)
• Add byte size parameter for number of data bits of serial port communication (#378)
• Accept non null terminated string on unpacking (#382)
• Always ensure null terminated string buffer and raise warning otherwise (#377)
• Declare array inputs of external C functions const (introduced in Modelica 3.5) (#389)
• Update SimulationX specific binaries (#399)

Bug fixes:

• Fixed process priority not reset (#44)
• Fix linker errors due to multiply defined symbols (#385)
• Fix CLOCK_MONOTONIC not available in -std=c89 (#383)

Other (minor) fixes and improvements (full changelog: v2.1.1...v2.2.0)

Modelica_DeviceDrivers v2.1.1

• Fix error in Linux MDD_getTimeMS (#363)
• Update SimulationX specific binaries (#361)

Modelica_DeviceDrivers v2.1.0

Enhancements:

• Added parameter useRecvThread also for clocked UDPReceive variant (#342).
• Added option for not unlinking shared memory partition at process termination (#339).
• Updated paho.mqtt.c to v1.3.10 (#355).

Bug fixes:

• Fixed RealtimeSynchronize block "clock_nanosleep" error on Linux (#357).
• Fixed MDD_TCPIPServer_Send(...) return value, so that it works as described in the documentation "On success, return the number of bytes sent, 0 if operation would block, -1 on non-fatal error" (#323).
• Serial port interface on Windows: Fixed spurious byte sent at the end of a simulation (#352).

Other (minor) fixes and improvements.

Modelica_DeviceDrivers v2.0.0

Migrated from Modelica Standard Library 3 (MSL 3) to MSL 4 -> Non-backwards compatible release!

However, apart from the MSL 4 dependency this release is compatible to previous releases and no update of user libraries is necessary apart from migrating to MSL 4.

Enhancements:

• Added all license files to better assist tool vendors in distribution of source or binary files (#313 ).
• Updated 3rd-party library paho.mqtt.c to v1.3.4 ( #320).

Bug fixes:

• Fixed small issues in the SBHS Board example (#318).

Modelica_DeviceDrivers v1.8.2

Updated Linux MQTT binary dependencies. The updated libraries are compiled with the -fPIC flag, which fixes a related FMU generation problem (#306).

Modelica_DeviceDrivers v1.8.1

Fix declaration of MDD_spaceMouseGetData in external C code (#305)

Modelica_DeviceDrivers v1.8.0

Enhancements:

• TCP/IP server communication (#296). In addition to the existing TCP/IP client blocks (see #78) there are now also blocks for setting up a TCP/IP server. See examples Blocks.Examples.TestSerialPackager_TCPIPServer and Blocks.Examples.TestSerialPackager_TCPIPServerMultipleClients.
• Enhanced real-time synchronization block (#290). Added an enhanced real-time synchronization block
  (Blocks.OperatingSystem.RealtimeSynchronize) and deprecated the existing block (Blocks.OperatingSystem.SynchronizeRealtime). The deprecated block is known to not working well with recent Dymola versions (e.g., Dymola 2020). The new RealtimeSynchronize block supports a sample-based real-time synchronization mode which is recommended for more deterministic, less solver sensitive behavior. See example Blocks.Examples.TestRealtimeSynchronize.
• An utility block for debugging purposes which prints a message when triggered by an event (#289).
• Updated 3rd-party library paho.mqtt.c to v1.3.1 (#293)

Bug fixes:

• Fixed Spacemouse not working under Windows 10 bug (#289).
• More similar behavior for getMACAddress() in Windows and Linux (#263).

Other (minor) fixes and improvements.

Modelica_DeviceDrivers v1.7.1

Fix backwards compatibility (#284)

Modelica_DeviceDrivers v1.7.0

Enhancements:

• Uses latest version of Modelica Standard Library (v3.2.3).
• Option for using blocking UDP receive calls (#275). On the function interface level an optional third argument in the UDPSocket constructor allows to create the external object without starting a dedicated receive thread (default: useRecvThread=true). On the block interface level (block UDPReceive) a new parameter useRecvThread (default: useRecvThread=true) allows to select the desired behavior. See example Blocks.Examples.TestSerialPackager_UDPWithoutReceiveThread.
• Added parameter enable (default: enable=true) for conditionally enabling or disabling the real-time synchronization within the Blocks.OperatingSystem.SynchronizeRealtime block (#270).
• Update OpenSSL to 1.0.2r (#280).

Bug fixes:

• EmbeddedTargets.AVR: Only start the RT synch timer once (#274).
• EmbeddedTargets.AVR: Fixed reading of digital pins (#266).
• Fixed Cygwin build (#271).
• Fixed scale factor calculation error in JoystickInput block (#272).
• Fix missing byte copy of \0 in external C code function MDDEXT_SerialPackagerGetString() (#273).

Other (minor) fixes and improvements.

Modelica_DeviceDrivers v1.6.0

Enhancements:

• Support for MQTT (Message Queuing Telemetry Transport protocol) client communication (see #130, #256).
• Utility function to retrieve MAC address (Utilities.Functions.getMACAddress, see #255).
• Utility function to generate a UUID (Utilities.Functions.generateUUID(), see #244).
• Number of received bytes in UDPReceive block is provided as output (see #236).
• Scalable real-time synchronization (see #215).

Adaption of the new Modelica Association license for libraries: The 3-Clause BSD License (see #238, #264). The C-code parts of the library were already BSD 3-Clause licensed, but the Modelica code was licensed under the Modelica License 2. Since Modelica Association projects, most notably the Modelica Standard Library (MSL), changed from Modelica License 2 to the BSD 3-Clause license, the Modelica_DeviceDrivers library follows this development.
