Message box is a short displaing message over the current screen

this will be more efficient in terms of power consumption - GPS thread may sleep on a semaphore

I temporary removed -flto flag from compiler/linker switches as Arduino/stm32duino sources do not compile with this flag.
Obviously this is a helpful option that needs attention later

reset code happens in begin() method of a main class. This ties all library to arduino (dependency on delay() and pinWrite()). It is reasonable to move this out from a main class. Display Driver implementation looks like a best place for this.

Depends on adafruit/Adafruit_SSD1306#87

to fit the following data:

• direct distance between starting and current point
• number of days in active/total time

Perhaps this will allow avoiding abbreviations

It can't display 16 8-pixel wide symbols on 128 pixels display, last symbol gets wrapped to a new line.

Particularly this

... and adjust CurrentTimeScreen and TimeZoneScreen

helper class that implements Printable interface and can print:

• time
• date (?)
• integers and float numbers with defined number of digits, precision, leading zeros/spaces, etc

On Holux M241 this sign is indicating that there is no GPS signal and displayed time is approximate

Screen should display:

• overall GPS status (position detected or not)
• Number of visible satellites
• Horizontal accuracy (vertical accuracy?)
• signal quality?
• Satellites signal power?

Preferably for all, but SD and display are the most critical. Perhaps GPS as well

to allow altering library configuration

A screen than wraps 3 odometers, displays some basic information, and drives all odometers at once

• figure out how to calculate it. HDOP/VDOP seems is not a good answer. It seems we need to enable GPGST sentence somehow
• Settle these values on GPS stats screen

... and fix existing code

Default date 1.1.1970 is displayed wrong if negative time zone selected (e.g.-3:00)

Screen should include:

• Current altitude in selected units (meters, feets)
• vertical speed

Currently it uses stm32generic implementation and polls SerialUART1 by calling available() method. It may be pretty power consuming.

Handling incoming bytes on interrupts will allow accumulate bytes in a buffer and wake up core when line is received

consider cmake-arduino

There are services that provide PID for free

When pressing POI button current position should be stored as track waypoint

Screen should include:

• Current speed in selected units (km/h, mph)
• Current heading
  -- major direction (N, NW, W...)
  -- heading degree

track meter is intended to measure short track parameters:

• distance
• time
• avg speed
• max speed
• altitude difference
• incline?
