From ad91454574ad1f0fad73923d04d6d1e037e45fed Mon Sep 17 00:00:00 2001 From: Michael Graf Date: Tue, 20 Nov 2018 15:55:35 +0100 Subject: Adaptive debounce logic The debounce filtering reports a key/switch change directly, without any extra delay. After that the debounce logic will filter all further changes, until the key/switch reports the same state for the given count of scans. So a perfect switch will get a short debounce period and a bad key will get a much longer debounce period. The result is an adaptive debouncing period for each switch. This value defines how often the same key/switch state has to be detected in successive reads until the next key state can be reported. In other words this value defines the minimum debouncing period for a switch. --- keyboards/ergodox_ez/config.h | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-) (limited to 'keyboards/ergodox_ez/config.h') diff --git a/keyboards/ergodox_ez/config.h b/keyboards/ergodox_ez/config.h index 7a350183b1..ee768853a9 100644 --- a/keyboards/ergodox_ez/config.h +++ b/keyboards/ergodox_ez/config.h @@ -85,17 +85,20 @@ along with this program.
