Re: [Discuss-gnuradio] Out of Tree Block Not Showing up in GRC

[Ron Economos]

Here's an even more basic example that doesn't use
the opt tag. It shows my complete cluelessness about
xml, but it works.

Thanks for the response, I was looking at the opt tags and I am still confused about how to do it. Do I need to set it up like this:

  <make>specsense.energy_detector_sink_f($vlen, $eta, $white_space.val, $samp_rate, $cntr_freq, $verbose)</make>

  <param>
    <name>Desired Detection</name>
    <key>white_space</key>
    <type>bool</type>
    <option>
      <name>Open Band</name>
      <value>True</value>

      <opt>val:True</opt>

    </option>
    <option>
      <name>Closed Band</name>
      <value>False</value>
      <opt>val:False</opt>
    </option>
  </param>

  <param>
    <name>Verbose</name>
    <key>verbose</key>
    <type>bool</type>
    <option>
      <name>Yes</name>
      <value>True</value>
      <opt>val:True</opt>
    </option>
    <option>
      <name>No</name>
      <value>False</value>
      <opt>val:False</opt>
    </option>
  </param>

Thanks,

I have two out of tree blocks I want to add to GRC, everything compiles and installs correctly except for the GRC component (not shown in GRC). So this should be an XML issue and I think it is related to my attempts at making a drop down option choice concerning the detection of white space/closed frequencies and verbose output. My XML is attached below and you can see that under Params Desired Detection and Verbose have options.

When I look at other stock GNU Radio block's XML like the low pass filter, I see that some params have opt tags. Do I need these also, if so how would I use them in my case?

Thanks,
