Main Structure in Arduino Code:

Interfaces:

• I_Component: every object that should have a setup and be called in the main loop inherits from this interface
• I_BTSender : every object that should send data through bluetooth inherits from this interface

Interation:

• button object allows you to get a signal from the button.
  • button.wasPressedOnce() returns True if shortly pressed
  • button.wasPressedOnceLong() returns True if pressed longer than duration seconds
• display object allows you to print in the LCD-Screen
  • display.setCursor(col, lin)
  • display.print("Hello") prints at the cursor
• scorer object computes the scores using the sensor values.
• sensorPrinter object uses the display to print the sensor values.

Sensors:

• sonar object allows you to get values from one sonar (not used)
• sonarCollection object allows you to get values from multiple sonar objects. It contains a vector of sonars
• imu object interacts with the IMU through the I2C bus
• gps object allows you to get the values of the current position.

Communication:

• bluetooth object gathers the data from the bluetooth sender objects and deals with the bluetooth connection.

Timing:

• Timer: timer objects allow to measure the time beetween two times (tic() and toc())
• Coordinator: coordinator allows components to do something in the loop if "their time has come"

Branching:

• main: main code for the product. Never push on it.
• develop: development branch with changes coming.
• feature branches : short living branches to implement new features. Merge them on develop with --no-ff to prevent fast forwarting if you are sure that the code works.

Main Structure of App Code:

Model:

• Model: main class for adding and retrieving safety data
• SafetyScore : model for safety score
• SafetyIncident : model for safety incident

Managers:

• LocationManager : retrieves current user location
• BluetoothManager : creates conenction with 6ense device. Reads data every second and stores them in model

Views:

• MainView : fullscreen view containing all views

Components

• MapRouteDrawer : colorizes the route according to safety score increment/decrement
• ScoreView : view of all safety scores
• MapView : view of integrated Apple Map
• RideButtonView : start and stop button for recording ride
• IncidentCardView : popup view of safety incidents
