Transforms its input into frequency (Hz: cycles per second)
Divides its input value by the time elapsed since the last reading.
multiplier | Output is multiplied by this parameter before being output, as a way to adjust the scale of the ouput. For example, if you're calculating the frequency of engine revolutions and you're sensing 4 signals per revolution (such as with 4 magnets on the flywheel), set multiplier = 0.25 to convert the total signals into "revolutions". |
config_path | Path to configure this transform in the Config UI. |

overridevirtual |
Returns a configuration schema that specifies the key/value pairs that can be expected when calling get_configuration(), or are expected by set_configuration(). The schema will be in JSON Schema format

overridevirtual |
Returns the current configuration data as a JsonObject. In general, the current state of local member variables are saved to a new object created with JsonDocument::as<JsonObject>() and returned.

overridevirtual |
Sets the current state of local member variables using the data stored in config.
