First step for datafield

Here is the simple code for testing:

import Toybox.Activity;
import Toybox.Lang;
import Toybox.Time;
import Toybox.WatchUi;

class ZeroPowerView extends WatchUi.SimpleDataField {
  // Set the label of the data field here.
  function initialize() {
    SimpleDataField.initialize();
    label = "Zero Power";
    System.println("function initialize");
  }

  // The given info object contains all the current workout
  // information. Calculate a value and return it in this method.
  // Note that compute() and onUpdate() are asynchronous, and there is no
  // guarantee that compute() will be called before onUpdate().
  function compute(info as Activity.Info) as Numeric or Duration or String or
      Null {
    // See Activity.Info in the documentation for available information.
    System.println("function compute");
    return 0.0;
  }
}

Not sure why this exact problem is happening to you, but the sim is notoriously flaky. Are you getting any error message in the console, such as "Could not connect to the simulator"?

Personally when something like this happens to me, I just try to rebuild and re-run the app over and over again, until it finally works. Sometimes I close and reopen the sim, too.

If you have a physical Edge 1040 device, you could always copy the PRG from the bin folder onto the device (in \GARMIN\APPS), to see the app in action. I realize you'd rather test in the sim first tho.

I try to create my own datafield. It should sum the time, where cadence and/or power is zero.

Is this actually something you need, or are you only doing it for the purposes of learning CIQ.

If you actually need this data field, my CIQ data field Appbuilder 5 can help.

The following settings should work for you:

- Label: CAD/POW 0 TIME (or whatever you want)

- Display Format: Time

- Formula: sum(not(power) or not(cadence))

This formula actually counts the number of seconds that either power and/or cadence is 0 or null.

If you want the number of seconds that either power and/or cadence is 0 (and not null), use the following formula:

sum(power eq 0 or cadence eq 0)

Here is the terminal output when I run without debugging. Chossing monkeyc as debugger:

But should I not get the prinln command in terminal? Even this is not printing.

println output should show in the debug console in VSC,  Make sure you use the latest SDK.  You might also see things there if there was a problem starting your app in the sim.  There could be a timeout for example..

If you don't have a background service, turn off the background permission.  If you do, annotate the code you need in the background with (:background)

Never seen anything like this before, but it seems like something that happens every second, so maybe something with compute()

Which monkey extension I need to add in VSS?

this two I have installed

If you've never had anything run in the sim, what I'd do, is in VSC, do Monkey C:New project, and have that create a simple data field (it uses a template from the SDK), and try running that with no changes to that code.  If that doesn't run, there is something about how you are set up.  If it does run, make minor changes based on your code and see what breaks it.

Remove the one at the bottom.  You only want the one from Garmin

Did all suggestions .. nothing helps. Deinstalling VScode and reinstall. Same.

Now I use my MacBook and working.

But now I need the current Power and current cadenz from a running activity How can I get this info in:
