Points Radar (GPS)

Shows selected points around current position. Aimed to give navigation ability for watches without maps and courses.

• Fonts are very small, to fit as many points as possible.
• Each point has distance in straight kilometers from current position (ultra small font).
• Points locations are entered in sync app, each point can be named.
• Point "s" is auto added at activity start location.
• 10 km radius, points within range are placed according to distance, further at the edge.
• Distances refresh about every 10 seconds (counter c var) and only when datafield is visible (auto call onUpdate() function), to reduce calculations.
• The Radar rotates, points are shown about in their directions.

Usage

Enter Points

• Point format is: latitude,longitude,name - separated by comma ,
• Latitude and longitude must use dot . as decimal separator
• Name is optional
• Example: ##.######,##.######,alfa or ##.######,##.######

Suggestions

• Use very short names, to keep the Radar readable.
• Choose points with some distance between. Points too close, can overlap.
• If points overlap anyway - turn around, this changes their positions and could be easier to see them.

Run

• Copy compiled Points.prg to the APPS\ directory.
• Select: Activity Settings → Data Screens → Screen # → Field # → Connect IQ → Points.

Compile

Points.prg

monkeyc -y dev_key.der -f PointsRadarGPS\monkey.jungle -r -o Points.prg

openssl genrsa -out dev_key.pem 4096

Optimization

Points_opt.mc

Size can be slightly reduced by hardcoding:

• text color: dc.setColor(0x000000,-1);
• x and y (screen center): xp=107+... and yp=90+... and dc.fillRectangle(107, 90,...);
• r (radius): maxr=82/... and rr=82;
• settings array (points): set=["##.######,##.######,alfa", "##.######,##.######"];
