acquisitionjlink

<script type="text/x-red" data-help-name="acquisition jlink out">

Allow to define and/or select a Jlink probe configuration (probe name), open and close the connection and send commands to the selected probe.

Properties​

Probe Configprobe configuration

This property allows to define and/or select a probe configuration (probe name)

Namestring

Name of the node in the flow, "acquisition out" if empty.

Input​

Each input msg will need a topic and a payload to be processed

topicstring

The topic possible values are

  • read to send a command of one shot read
  • start to send a command to START acquisition
  • stop to send a command to STOP acquisition

payloadobject

The payload is an object representing the variables group configuration defined in the variables node. The payload object holds several properties summarizing what have been set in the configuration panel of the variables node.

  • groupname string
  • variablelist array of variable

Details​

The acquisition out node is designed to be typically front linked with one or several variables nodes

<script type="text/x-red" data-help-name="acquisition jlink in">

Allow to define and/or select a Jlink probe configuration (probe name), and receive data from the selected probe.

Properties​

Probe Configprobe configuration

This property allows to define and/or select a probe configuration (probe name)

Namestring

Name of the node in the flow, "acquisition in" if empty.

Output​

Two outputs are defined, one port labelled data for the measurement and one labelled error

The error output msg.payload is the error message string, the msg.topic defines the error level

The data output msg.payload is an object representing the variable measurements done at specific intervals.

payloadobject

The payload object holds several properties:

  • first boolean, true when this is the first measurement after a start.
  • groupname string, the name of the 'variable group' these measurements are referring to.
  • data array of array of duplets Each array of duplets is referring to a variable. Each duplet represents the result of a single target memory read.* x number, representing the timestamp
    • y number, representing the read value in memory target

The following example shows an output msg for an acquisition in node:

      {
        "payload": {
          "data": \[
            \[
              {
                "y": 0,
                "x": 1560850927936
              }
            \],
            \[
              {
                "y": 0,
                "x": 1560850927936
              }
            \],
            \[
              {
                "y": 463,
                "x": 1560850927936
              }
            \],
            \[
              {
                "y": 2048,
                "x": 1560850927936
              }
            \],
            \[
              {
                "y": 78,
                "x": 1560850927939
              }
            \]
          \],
          "first": false,
          "groupname": "nv\_group2"
        }
      }
