-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!
