From 97cecb517cd7bf75e1219c76a93bfe6964c07052 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 10 May 2009 22:57:19 -0700 Subject: [PATCH 1/1] Increase the initial accel/baro average to 1000 samples To get an accurate baseline of the launchpad state, take a longer average of the two sensors as the unit boots up.
