Multiple Trips for tangogps

This is a little mod for tangogps which

1) persists the Trip data, and

2) adds multiple independent trips (5).

I use tangogps on my Neo FreeRunner for an odometer in my old car. I wanted to have a separate trip settings for oil changes, and, since the fuel gauge doesn't work, for petrol fill-ups.

The changes are made to tangogps-0.9.6

Here is a src patch.

and here is a complete openmoko package binary.

A few usability notes:

Without this update tangogps starts the trip counter by default. With this mod there are now 5 separate trip counters - all are OFF by default.

Cycle through the separate trip counters using a new NEXT button.

When you first start up tangogps, cycle through the trip counters and turn on the ones you want running for your current trip.

Starting, Stopping, and Reseting a trip counter works the same as before with the caveat that the operation only affects the trip counter currently displayed on the screen.


Some additional changes being considered:

Add ability to name the trips instead of simply using the numbers 1,2..,5.

Add ability to create an unlimited number of trips instead of fixing the number (presently at 5).
