This protocol decoder takes a set of logic input signals, and interprets
|
|
their bit pattern according to user specifications as different kinds of
|
|
numbers, or an enumeration of e.g. machine states.
|
|
|
|
Supported formats are: signed and unsigned integers, fixed point numbers,
|
|
IEEE754 floating point numbers, and number to text mapping controlled by
|
|
external data files. (Support for half precision floats depends on the
|
|
Python runtime, and may not universally be available.)
|
|
|
|
User provided text mapping files can either use the JSON format:
|
|
{"one": 1, "two": 2, "four": 4}
|
|
or the Python programming language:
|
|
enumtext = { 1: "one", 2: "two", 3: "three", }
|
|
|
|
In addition to all enum values on one row (sequential presentation of
|
|
the data), a limited number of enum values also are shown in tabular
|
|
presentation, which can help visualize state machines or task switches.
