Debounce algorithms belong in this folder.
Here are a few ideas
1) Global vs Per-Key vs Per-Row
* Global - one timer for all keys. Any key change state affects global timer
* Per key - one timer per key
* Per row - one timer per row
2) Eager vs symmetric vs assymetric
* Eager - any key change is reported immediately. All further inputs for DEBOUNCE ms are ignored.
* Symmetric - wait for no changes for DEBOUNCE ms before reporting change
* Assymetric - wait for different times depending on key-down/key-up. E.g. Eager key-down, DEBOUNCE ms key up.
3) Timestamp vs cycles
* old old old code waits n cycles, decreasing count by one each matrix_scan
* newer code stores the millisecond the change occurred, and does subraction to figure out time elapsed.
* Timestamps are superior, i don't think cycles will ever be used again once upgraded.
The default algorithm is symmetric and global.
Here are a few that could be implemented:
debounce_sym_g.c
debounce_sym_pk.c
debounce_sym_pr.c
debounce_sym_pr_cycles.c //currently used in ergo-dox
debounce_eager_g.c
debounce_eager_pk.c
debounce_eager_pr.c //could be used in ergo-dox!
