From 3107546c04ec794e5ebbef669ee56bb790ffb578 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 5 Aug 2021 21:12:20 -0500 Subject: [PATCH] Revert "firmware: Make interrupt signal shorter (10us)" The longer duration is actually required, likely due to debouncing applied on the SoC side. Even 50us was unreliable.
