From da2c920b9f3378d5a18551e008c1da5dace1e0ef Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Mon, 7 May 2012 21:53:53 -0700 Subject: [PATCH] altosui: Try to make telem tick counts match eeprom telem files can have an extra wrap or two of tick count if they start recording a long time before the flight. Account for this so that the CSV file output from each have matching tick values.
