First step for datafield

Hello!

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

Should running on a Edge1040

I setup Visual Studio, install Monkey C and create first project. When I click on "Run without debugging" I choose the Edge1040 and the simulator start.

But there I have only a blank screen. I thought it will display the edge 1040?

Is there a tutorial for a simple datafield on a edge 1040?

Thank you!

I test this now:

    function compute(info as Activity.Info) as Numeric or Duration or String or Null {
        // See Activity.Info in the documentation for available information.
        var cad = info.currentCadence;
        var pwr = info.currentPower;
        var spd = info.currentSpeed;

        if (spd > 0){
            if (cad == null){
                zeroPower += 1;
            } else if (pwr == null){
                zeroPower += 1;
            }
        }
        return zeroPower;
    }

I try to play a GPX file from a existing workout:

Simulation => FIT/GPX Playable file => Load the file an click the Play icon.

But it seems the data never changed.

       if (info has :currentCadence) {
            cad = info.currentCadence;
            if (cad == null) {
                cad = 0;
            }
                
        } else {
            cad = -1;
        }

        if (info has :currentPower) {
            pwr = info.currentPower;
            if (pwr == null) {
                pwr = 0;
            }
                
        } else {
            pwr = -1;
        }

        if (info has :currentSpeed) {
            spd = info.currentSpeed * 3.6;
            if (cad == 0 or pwr == 0){
                zeroPower = zeroPower.add(new Time.Duration(1));
            }
        }

        return secondsToTimeString(zeroPower.value());

ok, so far I think this is correct.

I did not find any info, how I can save this info. In some IQ fields I see at the end of a workout:

How can I store this info also?

And is it possible to save the counter while workout? Sometimes it happen, that the Edge reboot while a workout is running. Could I reload then the zeroPower variable?

Thanks

you can create session level fit field(s) and store it there
