Hello, 

guys anyone know how to make the onUpdate() event run every second?? 

I try to create my own watch face for vivoactive 3 and i create getHeartRate() function and its work very well when i look at the screen and the screen light turn on and when its off 

the heart rate text is stack on the last heart rate,

this is the code: 

function getHeartRate(){
var heartRateText = "";
var currentHeartRate = Activity.getActivityInfo().currentHeartRate;
if(currentHeartRate != null){
heartRateText = currentHeartRate.toString();
}else{
var heartRateHistory = ActivityMonitor.getHeartRateHistory(1, true);
var heartRateSample = heartRateHistory.next();
var heartRate = heartRateSample.heartRate;
if(heartRateSample == ActivityMonitor.INVALID_HR_SAMPLE){
heartRateText = "";
}else{
heartRateText = heartRate;
}
}
var heartRateDisplay = View.findDrawableById("HeartRateDisplay");
heartRateDisplay.setText(heartRateText.toString());
}

and i call this event in my onUpdate() event. 

Ty

    You can use eclipse.  Just import the project, and run it.  There's a sticky in this forum about switching to money C, and here's a blog post:

    Yes.  The thread I pointed at talks about also doing HR.  You only want to update it if it changes when you use onPartialUpdate.

    i understand nothing with the code that you send me i just have to find tutorial because i create beautiful watch face in the monkey c: new project but now i dont understand what is all this code like onPartialUpdate and can1Hz and more things in the project that you give me like where is the layout.xml file and why you do dc.drawText if you can create label in the layout.xml and just setText in the onUpdate() function like this: look at the getDate function i just setText on the label i create, and now i need to do alot of things like dc.drawText(x,y....) and where i should do it in onUpdate or in onPartialUpdate???????

    The code in the 1hz thread is really basic, and you need to understand it  If you look at how seconds are done, HR would be done much the same way

    Start by looking at the samples in the SDK.  There are simple examples of lots of things there.
