saleae.data
class saleae.data.GraphTime(datetime: datetime, millisecond=0, *, microsecond=0, nanosecond=0, picosecond=0)
A high-precision wall clock time. 
The primary way to use this type is to subtract two GraphTimes to produce a GraphTimeDelta. GraphTimeDeltas may be freely added and subtracted from each other, and converted to floating point seconds. They can also be added to or subtracted from GraphTimes to produce a suitable offset GraphTime.
Constructs a GraphTime using a datetime, and optionally sub-millisecond precision values.
The sub-millisecond precision values must be converible to float.
__add__()
Add a GraphTimeDelta value to produce a new GraphTime.
__str__()
Converts GraphTime to an ISO 8601 string with picosecond precision.
Timezone is always UTC, using the Z suffix.
__sub__()
Subtract a GraphTime or GraphTimeDelta value.
When subtracting a GraphTime, produces a GraphTimeDelta.When subtracing a GraphTimeDelta, produces a GraphTime.
as_datetime(self: GraphTimedatetime)
Produces a datetime value that is as close as possible to the given value.
The produced datetime is always timezone aware an in the UTC timezone. Local time can be procured using the standard Python datetime conversion functions.
class saleae.data.GraphTimeDelta(second=0, millisecond=0, *, microsecond=0, nanosecond=0, picosecond=0)
A high-precision duration.
Constructs a GraphTimeDelta using numerical values.
All values must be convertible to float. Multiple prefixes may be specified, the resulting value will be all the values added together.
__add__()
Add a GraphTimeDelta value to produce a new GraphTimeDelta.
__eq__()
Determine if two GraphTimeDelta values are equal, up to a tolerance.
__float__()
Convert to a floating point number of seconds. Note that this can cause a loss of precision for values > 1ms.
__ge__()
Determine if the first GraphTimeDelta value is greater than or equal to the second, up to a tolerance.
__gt__()
Determine if the first GraphTimeDelta value is greater than the second, up to a tolerance.
__le__()
Determine if the first GraphTimeDelta value is less than or equal to the second, up to a tolerance.
__lt__()
Determine if the first GraphTimeDelta value is less than the second, up to a tolerance.
__ne__()
Determine if two GraphTimeDelta values are not equal, up to a tolerance.
__sub__()
Subtract a GraphTimeDelta value to produce a new GraphTimeDelta.
class saleae.data.AnalogData(raw_samples: ndarray, voltage_transform_gain: float, voltage_transform_offset: float, start_time: saleae.data.timing.GraphTime, end_time: saleae.data.timing.GraphTime)
iter()
Iterates over the samples in this instance as voltage values.
sample_count
The number of samples contained in this instance.
slice_samples(slice: slice) -> saleae.data.AnalogData
Allows creating an AnalogData from a subset of this one's samples.
samples
Samples after applying voltage scaling.
saleae.range_measurements
class saleae.range_measurements.DigitalMeasurer(requested_measurements: List[str])
class saleae.range_measurements.AnalogMeasurer(*args, **kwargs)
saleae.analyzers
class saleae.analyzers.HighLevelAnalyzer()
Base class for High Level Analyzers. Subclasses must implement the decode() function
decode(frame: saleae.analyzers.high_level_analyzer.AnalyzerFrame)
Decode a frame from an input analyzer, and return None or 1 or more AnalyzerFrame objects.
class saleae.analyzers.AnalyzerFrame(type: str, start_time: saleae.data.timing.GraphTime, end_time: saleae.data.timing.GraphTime, data: dict = None)
A frame produced by an analyzer. The types of frames and the fields in each will depend on the analyzer.
Variables
​type (str) – Frame type
start_time (saleae.data.GraphTime) – Start of frame
end_time (saleae.data.GraphTime) – End of frame
data (dict) – Key/value data associated with this frame
class saleae.analyzers.StringSetting(**kwargs)
String setting.
class saleae.analyzers.NumberSetting(*, min_value=None, max_value=None, **kwargs)
Number setting, with an option min_value/max_value.
class saleae.analyzers.ChoicesSetting(choices, **kwargs)
Choices setting.
