Forerunner 965 accelerometer and gyroscope access

Z 3 months ago

Hi all,

I am working on creating an app for gait recognition for my research, I am trying to access accelerometer data and gyroscope data and store them into a fit file to analyse. However, I am not able to access those two sensors and I am a bit confused about what to do, I tried with something like this:

var info = Sensor.Info;

var keys = [];

if (info has :accel) { keys.add("accelerometer"); }

if (info has :gyroscope) { keys.add("gyroscope"); }

if (info has :mag) { keys.add("magnetometer"); }

if (info has :temperature) { keys.add("temperature"); }

System.println("Available sensor types: " + keys.toString());

I try to print the sensors availble, as you can see, the result consists [acceletometer, magnetometer and temperrature].
I am generally confused about how to access those sensors and if they are activated, plus, does it has anything to do with the watch itself? I am using an Garmin Forerunner965 and I can't find any method to activate developers mode inside the watch.

Thank you very much for your time and patience!

Hi.

Try like this

#1 options

var options = {

:period => 1, // 1 second sample time

:accelerometer => {

:enabled => true, // Enable the accelerometer

:sampleRate => 100, // N samples

:includePower => true,

:includePitch => true,

:includeRoll => true

:gyroscope => {

:enabled => true,

:sampleRate => 100

}

};

#2 Init

OnStart method:

Sensor.registerSensorDataListener(method(:accelCallback1), options);

#3 collect data

function accelCallback1(data as $.Toybox.Sensor.SensorData) as Void {

...

mX = data.accelerometerData.x;

mY = data.accelerometerData.y;

mZ = data.accelerometerData.z;

pitch = data.accelerometerData.pitch;

pow = data.accelerometerData.power;

roll = data.accelerometerData.roll;

gyroX = data.gyroscopeData.x; // Float in deg/sec.

gyroY = data.gyroscopeData.y;

gyroZ = data.gyroscopeData.z;
