Code Optimization
|
|
|
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The original working code is about 4k (not counting the pt3 file)
|
|
|
|
|
and has an overhead of roughly 20% when playing a song interrupt-driven
|
|
|
|
|
at 50Hz.
|
|
|
|
|
|
|
|
|
|
I'm keeping some stats here as I try to optimize the size and speed.
