list_decoder_manifest_signals

IoTFleetWise.Client.list_decoder_manifest_signals(**kwargs)

A list of information about signal decoders specified in a decoder manifest.

Note

This API operation uses pagination. Specify the nextToken parameter in the request to return more results.

Request Syntax

response = client.list_decoder_manifest_signals(
    name='string',
    nextToken='string',
    maxResults=123
)

Parameters:

• name (string) –

  [REQUIRED]

  The name of the decoder manifest to list information about.

• nextToken (string) –

  A pagination token for the next set of results.

  If the results of a search are large, only a portion of the results are returned, and a nextToken pagination token is returned in the response. To retrieve the next set of results, reissue the search request and include the returned token. When all results have been returned, the response does not contain a pagination token value.

• maxResults (integer) – The maximum number of items to return, between 1 and 100, inclusive.

Return type:

dict

Returns:

Response Structure

• (dict) –

  • signalDecoders (list) –

    Information about a list of signals to decode.

    • (dict) –

      Information about a signal decoder.

      • fullyQualifiedName (string) –

        The fully qualified name of a signal decoder as defined in a vehicle model.

      • type (string) –

        The network protocol for the vehicle. For example, CAN_SIGNAL specifies a protocol that defines how data is communicated between electronic control units (ECUs). OBD_SIGNAL specifies a protocol that defines how self-diagnostic data is communicated between ECUs.

      • interfaceId (string) –

        The ID of a network interface that specifies what network protocol a vehicle follows.

      • canSignal (dict) –

        Information about signal decoder using the Controller Area Network (CAN) protocol.

        • messageId (integer) –

          The ID of the message.

        • isBigEndian (boolean) –

          Whether the byte ordering of a CAN message is big-endian.

        • isSigned (boolean) –

          Whether the message data is specified as a signed value.

        • startBit (integer) –

          Indicates the beginning of the CAN signal. This should always be the least significant bit (LSB).

          This value might be different from the value in a DBC file. For little endian signals, startBit is the same value as in the DBC file. For big endian signals in a DBC file, the start bit is the most significant bit (MSB). You will have to calculate the LSB instead and pass it as the startBit.

        • offset (float) –

          The offset used to calculate the signal value. Combined with factor, the calculation is value = raw_value * factor + offset.

        • factor (float) –

          A multiplier used to decode the CAN message.

        • length (integer) –

          How many bytes of data are in the message.

        • name (string) –

          The name of the signal.

      • obdSignal (dict) –

        Information about signal decoder using the On-board diagnostic (OBD) II protocol.

        • pidResponseLength (integer) –

          The length of the requested data.

        • serviceMode (integer) –

          The mode of operation (diagnostic service) in a message.

        • pid (integer) –

          The diagnostic code used to request data from a vehicle for this signal.

        • scaling (float) –

          A multiplier used to decode the message.

        • offset (float) –

          The offset used to calculate the signal value. Combined with scaling, the calculation is value = raw_value * scaling + offset.

        • startByte (integer) –

          Indicates the beginning of the message.

        • byteLength (integer) –

          The length of a message.

        • bitRightShift (integer) –

          The number of positions to shift bits in the message.

        • bitMaskLength (integer) –

          The number of bits to mask in a message.

  • nextToken (string) –

    The token to retrieve the next set of results, or null if there are no more results.
