Some classes just takes a lot longer than you would expect. Both teachers and students would benefit from knowing how long these assignments take. You're wearing your watch all day long. Next time you start a project, just load a name onto your watch, and start the timer.
What it does
The pebble watch has a persistent storage function that allows the user to submit the project name from their phone to be sent to their watch. On the watch, the user can then select the project name, and create a log of the date and duration of their work sessions, that will also be stored in permanent pebble watch storage until the user chooses to delete it.
How we built it
We then utilized pebble's menuLayers and clean window stack implementation to create a three window system that goes from list of projects -> the project's timed sessions -> the timer/stopwatch.
Challenges we ran into
- Trying to manipulate and store strings, that are built as character arrays in C
- C pointers in general but specifically getting "incomplete struct errors" due to not specifying our list length
- Figuring out when to allocate storage (anything that goes into permanent storage) and when we can use the heap
- Learning the basic functions for creating pebble's windows, menu_layers, text_layers, timing functions, and C's time structure
Accomplishments that we're proud of
- Finishing a workable prototype during our first hackathon
What we learned
We learned how to develop a project that integrates multiple programming languages, the importance of memory management in hardware with limited storage, and storing information into permanent memory.
What's next for pebbleStudyTracker
The graphical user interface can be strongly improved on - especially our current stopwatch implementation.
