From c40583e19eebae50f6b024d8285d2703e2522364 Mon Sep 17 00:00:00 2001 From: "Luis Claudio R. Goncalves" Date: Mon, 10 Jun 2024 10:23:14 -0300 Subject: rtla/osnoise: set the default threshold to 1us Change the default threshold for osnoise to 1us, so that any noise equal or above this value is recorded. Let the user set a higher threshold if necessary.
