|
||||
* @brief Main Driver for the Week 6 "Background Music" Lab. This program uses
|
||||
* a similar menu style to the previous lab. The user is given a new option to
|
||||
* play 3 different hard coded songs in arrays of "Note" structs, provided by
|
||||
* the piezoSpeaker.h file. However, the user can now select whether or not the
|
||||
* music should play in the background to allow other functionality.
|
||||
* Experience: This lab was a challenge for me. I found that understanding
|
||||
* interrupts, and mainly how to configure them, was a roadblock that took me
|
||||
* awhile to figure out. Cleary, as this lab is incomplete I was not able to
|
||||
* fully implement my design. I do have a general idea of the structure of the
|
||||
* program I would like to implement. For my own sake and sanity, I am going to
|
||||
* work on trying finish this lab at the very least over break just so I can
|
||||
* see what it is like to get an interrupt driven program working. In this
|
||||
* case I just managed my time wrong and let myself get behind on labs.
