Hi,
As a first timer i'm trying to create an app that does something with the accelerometer data, however, i can't even succeed in just printing the data on the watch screen.
I'm doing everything in Visual Studio Code and tried simulating with different types of watches.
I have an ___App.mc file which is basically empty except for:
public function getInitialView() as Array<Views> {
var mainView = new $.MyView();
return mainView as Array<Views>;
}
And the ___view.mc in its simplified (yet still crashing) version:
import Toybox.Graphics;
import Toybox.Lang;
import Toybox.Math;
import Toybox.Sensor;
import Toybox.Timer;
import Toybox.WatchUi;
class MyView extends WatchUi.View {
private var _dataTimer as Timer.Timer?;
private var dt as Numeric; // [ms]
private var _accel as Array<Float>;
private var _width as Numeric;
public function initialize() {
View.initialize();
dt = 50.0;
_accel = new Array<Float>[3];
_width = 0;
}
public function onLayout(dc as Dc) {
_dataTimer = new Timer.Timer();
_dataTimer.start(method(:timerCallback), dt, true);
_width = dc.getWidth();
}
public function onShow() as Void {
}
public function onUpdate(dc as Dc) as Void {
dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_BLACK);
dc.clear();
dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_TRANSPARENT);
if (_accel != null) {
dc.drawText(_width / 2, 3, Graphics.FONT_TINY, "Ax = " + _accel[0], Graphics.TEXT_JUSTIFY_CENTER);
dc.drawText(_width / 2, 23, Graphics.FONT_TINY, "Ay = " + _accel[1], Graphics.TEXT_JUSTIFY_CENTER);
dc.drawText(_width / 2, 43, Graphics.FONT_TINY, "Az = " + _accel[2], Graphics.TEXT_JUSTIFY_CENTER);
} else {
dc.drawText(_width / 2, 3, Graphics.FONT_TINY, "no Accel", Graphics.TEXT_JUSTIFY_CENTER);
}
}
public function timerCallback() as Void {
var info = Sensor.getInfo();
if (info has :accel && info.accel != null) {
_accel = info.accel as Array<Float>;
}
WatchUi.requestUpdate();
}
public function onHide() as Void {
}
}
I've tried putting breaking points everywhere but it only stops in the initialize function and everything seems fine there.
Would be happy for some guidance what am i doing horribly wrong..
Thanks in advance.
