The Isotel IDM Python API Release Notes

Pre-Release 1.2.1 on 15. March 2023

  • Corrected (fixed) SFrame with FrameShort dict name in MonoDAQ protocols

  • Added support for templated EC modules

Beta-Release 1.2 on 21. March 2022

  • Fixed last colours to display in bokeh

  • Added support to Stream from Custom (TCP/IP) User Protocols

  • Added simple first order averaging IIR with tunable avg_k

  • Added Amplitude to the sinad_dB to the return val

Beta-Release 1.0b21 on 26. November 2019

  • Added signal test functions: rms() for dc/ac, sinad_dB(), enob()

  • Added spectrum analysis: tospectrum() with blackmanharris windows of 3,4 and 7 terms

  • Added fast pyqtgraph based: qscope() for real-time simultaneous presentation of signal and spectrum at the same time

Beta-Release 1.0b20 on 8. June 2019

  • Fixed monodaq.print_setup() to work with remote systems requiring user/pass

  • Added history dumping to monodaq main for bounded interval from, to, with optional scaling (down-sampling).

Release 1.0a19

  • Added flex non-equiv-distant interval sampling to collect() method, based on time samples as they arrive from devices themself.

  • Added until parameter to get() and get_value() methods. Requires idm-1.1a5/b5 and example. It allows retrieval of data with natural arrival from the devices in a bounded time frame interval.

Release 1.0a18 on 1. Feb 2019

  • Added support to instantiate inactive device and retrieve its latest status with get(), get_value(), and get_records()

Release 1.0a17 on 30. Jan 2019

  • Added Device.collect() method to continuously fetch samples from given parameter and output it as a generator, to be used by isotel.idm.signal methods in the same way as MonoDAQ_U.fetch()

  • Added incremental option to the signal.stream2signal() to continuously update slow signals, i.e. with signal.scope() method.

  • Increased number of decimals for MonoDAQ_U.fetch() to be able to observe every LSB

Release 1.0a16 on 23. Jan 2019

  • Aligned with the latest API from IDM 1.1b3

  • Gateway default time-out increased to 60 seconds (from 10 seconds) for slow networks

Release 1.0a15 on 5. Nov 2018

  • MonoDAQ time is left untouched after first synchronization to be compatible with the Dewesoft plugin.

Release 1.0a14 on 17. Oct 2018

  • Added Multi-Rate support to synchronous Multi-MonoDAQs fetch

Release 1.0a13 on 15. Oct 2018

  • Added class MonoDAQs_U with synchronous fetch from multiple MonoDAQs

  • Added EC class with helper function to configure common and channel options

Release 1.0a12 on 9. Oct 2018

  • Relaxed requirements, on MAC you would need to install as pip install isotel-idm requests==2.8.1

Release 1.0a11 on 7. Oct 2018

  • TSV format outputs no-value on None or NaN

  • MonoDAQ fixed mdu.reset() to properly clean on remote devices

  • pypy: Fixed not raised GeneratorExit exception

Release 1.0a9 on 5. Oct 2018

  • Fixed div by zero in digital only operation

  • MonoDAQ: added command line tool: python -m isotel.idm.monodaq -h

  • Signal: Added to TSV generator

Release 1.0a7 on 4. Oct 2018

  • Fixed digital only operation

Release 1.0a6 on 3. Oct 2018

  • Added packet counter checks to detect lost packets and to detect potential mis-alignment of signals from various streams.

  • In trigger single shot mode when signal is acquired, generator exists and consequently MonoDAQ_U stops streaming. So in the following example number of samples may be used as timeout until the first triggering:

    signal.trigger( mdu.fetch(2000000), precond=’DI1 < 0.5’, cond=’DI1 > 0.5’, P=200, N=200, single_shot=True)

  • MonoDAQ_U: added support for 7 channels

Release 1.0a5 on 30. Sep 2018

  • First published release supporting Isotel Precision & MonoDAQ-U-X products
