History¶
0.6.0 (2021-04-23)¶
Technix capacitor charger using either serial connection or Telnet protocol.
- Extensions, improvements and fixes in existing devices:
- In
dev.tiepie.TiePieOscilloscope
: redesigned measurement start and data collection API, incl. time out argument, with no/infinite time out option;
trigger allows now a no/infinite time out;
record length and trigger level were fixed to accept, respectively, floating point and integer numbers;
fixed resolution validation bug;
- In
dev.heinzinger.HeinzingerDI
and dev.rs_rto1024.RTO1024 instances are now resilient to multiplestop()
calls.In
dev.crylas.CryLasLaser
: default configuration timeout and polling period were adjusted;Fixed PSI9080 example script.
- Package and source code improvements:
Update to backward-incompatible
pyvisa-py>=0.5.2
. Developers, do update your local development environments!External libraries, like LibTiePie SDK or LJM Library, are now not installed by default; they are now extra installation options.
Added Python 3.9 support.
Improved number formatting in logs.
Typing improvements and fixes for
mypy>=0.800
.
0.5.0 (2020-11-11)¶
TiePie USB oscilloscope, generator and I2C host devices, as a wrapper of the Python bindings for the LibTiePie SDK.
a FuG Elektronik Power Supply (e.g. Capacitor Charger HCK) using the built-in ADDAT controller with the Probus V protocol over a serial connection
All devices poling status or measurements use now a
dev.utils.Poller
utility class.- Extensions and improvements in existing devices:
In
dev.rs_rto1024.RTO1024
: added Channel state, scale, range, position and offset accessors, and measurements activation and read methods.In
dev.sst_luminox.Luminox
: added querying for all measurements in polling mode, and made output mode activation more robust.In
dev.newport.NewportSMC100PP
: an error-pronewait_until_move_finished
method of replaced by a fixed waiting time, device operations are now robust to a power supply cut, and device restart is not required to apply a start configuration.
- Other minor improvements:
Single failure-safe starting and stopping of devices sequenced via
dev.base.DeviceSequenceMixin
.Moved
read_text_nonempty
up tocomm.serial.SerialCommunication
.Added development Dockerfile.
Updated package and development dependencies:
pymodbus
,pytest-mock
.
0.4.0 (2020-07-16)¶
- Significantly improved new Supercube device controller:
more robust error-handling,
status polling with generic
Poller
helper,messages and status boards.
tested with a physical device,
Improved OPC UA client wrapper, with better error handling, incl. re-tries on
concurrent.futures.TimeoutError
.SST Luminox Oxygen sensor device controller.
- Backward-incompatible changes:
CommunicationProtocol.access_lock
has changed type fromthreading.Lock
tothreading.RLock
.ILS2T.relative_step
andILS2T.absolute_position
are now called, respectively,ILS2T.write_relative_step
andILS2T.write_absolute_position
.
- Minor bugfixes and improvements:
fix use of max resolution in
Labjack.set_ain_resolution()
,resolve ILS2T devices relative and absolute position setters race condition,
added acoustic horn function in the 2015 Supercube.
- Toolchain changes:
add Python 3.8 support,
drop pytest-runner support,
ensure compatibility with
labjack_ljm
2019 version library.
0.3.5 (2020-02-18)¶

Fix development requirements specification (tox version).
0.3.4 (2019-12-20)¶
- New devices using serial connection:
Heinzinger Digital Interface I/II and a Heinzinger PNC power supply
Q-switched Pulsed Laser and a laser attenuator from CryLas
Newport SMC100PP single axis motion controller for 2-phase stepper motors
Pfeiffer TPG controller (TPG 25x, TPG 26x and TPG 36x) for Compact pressure Gauges
PEP 561 compatibility and related corrections for static type checking (now in CI)
- Refactorings:
Protected non-thread safe read and write in communication protocols
Device sequence mixin: start/stop, add/rm and lookup
.format() to f-strings
more enumerations and a quite some improvements of existing code
Improved error docstrings (
:raises:
annotations) and extended tests for errors.
