nitypes

library1.1.0pypypiunverified

Data types for NI Python APIs, providing analog, complex, and digital waveforms, frequency spectrums, complex integers, and time conversion. Current stable version is 1.0.1 (latest release). Development releases (1.1.0.dev2) are available. Release cadence is irregular.

Quickstart: import and basic usage of nitypes data types.

from nitypes import AnalogWaveform, DigitalWaveform, Scalar, Vector import numpy as np # Create an analog waveform analog_data = np.array([0.5, 1.2, -0.3], dtype=np.float64) t0 = 0.0 dt = 0.001 waveform = AnalogWaveform(data=analog_data, t0=t0, dt=dt) print(waveform) # Create a digital waveform digital_data = np.array([0b1010, 0b1100], dtype=np.uint8) digital_waveform = DigitalWaveform(data=digital_data, t0=t0, dt=dt) print(digital_waveform) # Create a scalar and vector scalar = Scalar(value=5.0) vector = Vector(data=np.array([1, 2, 3])) print(scalar, vector)

Debug

Known issues

breakingIn nitypes 1.0.1, the ordering of Digital Waveform Signal Indices was reversed. signal_index now starts from leftmost bit as highest index, opposite to 1.0.0. Code relying on index ordering must be updated.

fix

Update to nitypes>=1.0.1 and adjust any logic that assumes signal 0 is the most significant bit.

affects: <=1.0.0

gotchanitypes classes like AnalogWaveform and DigitalWaveform are not fully picklable in versions before 1.1.0.dev2. Unpickling may raise errors or produce incorrect data.

fix

Upgrade to nitypes>=1.1.0.dev2 to fix pickling issues.

affects: <1.1.0.dev2

deprecatedThe `unit` property was renamed to `units` for consistency in version 0.1.0-dev9. Using `unit` will raise AttributeError.

fix

Use `.units` instead of `.unit` when accessing unit metadata.

affects: >=0.1.0-dev9

gotchaType hints may break with numpy >= 2.4.x on nitypes versions before 1.1.0.dev2. Incompatible type stubs cause mypy errors.

fix

Upgrade to nitypes>=1.1.0.dev2 to get compatible type hints.

affects: <1.1.0.dev2
