/* Cleverness ensues
|
||||
*
|
||||
* The Adafruit library is written to let you go off and do whatever you need,
|
||||
* hooking into an interrupt to sort of act like a multitasking operating system,
|
||||
* interrupting your program periodically.
|
||||
*
|
||||
* That's smart, since it makes it easy to use,
|
||||
* but we want this to be responsive, and can't handle something barging in and taking up lots of time:
|
||||
* it makes things look really uneven as our display code pauses to fill the buffer.
|
||||
* Fortunately, we don't have to fill the entire buffer at once, we can trickle data in.
|
||||
* That's what this does.
|
||||
*
|
||||
* Since the entire program is polling, without ever calling delay,
|
||||
* and hopefully doing what needs to be done quickly,
|
||||
* we check to see if the music chip wants more data.
|
||||
* If it does, we give it one chunk, and only one chunk,
|
||||
* rather than filling its buffer back up completely.
|
||||
*
|
||||
* There is still some weirdness with this loop,
|
||||
* possibly because the SPI routines are masking interrupts used to increment millis.
|
||||
* But it's remarkably more fluid than the other way.
