From b829a1d2648abd0751e9d3505554547faf643425 Mon Sep 17 00:00:00 2001 From: Simon Arlott <70171+nomis@users.noreply.github.com> Date: Wed, 9 Jun 2021 08:23:21 +0100 Subject: Avoid 8-bit timer overflows in debounce algorithms (#12240) * Add fast_timer_t that is 16-bit or 32-bit based on architecture A 16-bit timer will overflow sooner but be faster to compare on AVR. * Avoid 8-bit timer overflows in debounce algorithms Count down remaining elapsed time instead of trying to do 8-bit timer comparisons. Add a "none" implementation that is automatically used if DEBOUNCE is 0 otherwise it will break the _pk/_pr count down. * Avoid unnecessary polling of the entire matrix in sym_eager_pk The matrix only needs to be updated when a debounce timer expires. * Avoid unnecessary polling of the entire matrix in sym_eager_pr The matrix only needs to be updated when a debounce timer expires. The use of the "needed_update" variable is trying to do what "matrix_need_update" was added to fix but didn't work because it only applied when all keys finished debouncing. * Fix sym_defer_g timing inconsistency compared to other debounce algorithms DEBOUNCE=5 should process the key after 5ms, not 6ms * Add debounce tests --- quantum/debounce/tests/sym_defer_pk_tests.cpp | 225 ++++++++++++++++++++++++++ 1 file changed, 225 insertions(+) create mode 100644 quantum/debounce/tests/sym_defer_pk_tests.cpp (limited to 'quantum/debounce/tests/sym_defer_pk_tests.cpp') diff --git a/quantum/debounce/tests/sym_defer_pk_tests.cpp b/quantum/debounce/tests/sym_defer_pk_tests.cpp new file mode 100644 index 0000000000..1f3061e59c --- /dev/null +++ b/quantum/debounce/tests/sym_defer_pk_tests.cpp @@ -0,0 +1,225 @@ +/* Copyright 2021 Simon Arlott + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
