break out of while loops to prevent hanging indefinitely

[daanvanhasselt]

In some cases the library would hang indefinitely when either the begin() or getEvent() function was called. In my case this happened with a faulty connector (VDD line disconnected). This is a quick and easy fix that allows the main program to continue operation after retrying for a maximum of 10 tries.

hiya! thanks so much for submitting a PR! we can review & merge PRs once they have passed continuous integration (CI). that means that code compiles cleanly for all tested platforms, is clang formatted so we maintain the same text formatting for all new code, and is doxygen documented.
if your code isnt passing, check the CI output (click on the red X next to the PR to scroll through the log and find where the error is

here is a tutorial on doxygen: https://learn.adafruit.com/the-well-automated-arduino-library/doxygen

and overall how to contribute PRs to libraries: https://learn.adafruit.com/contribute-to-arduino-with-git-and-github

once you get that green checkmark that indicates CI has passed, please comment reply to this post so we know its time for another review (we may not get notified on CI pass and miss that its time to look!)
