From fac34c12d7b6e8e5b516cd24b50127129a1409c7 Mon Sep 17 00:00:00 2001 From: kliment Date: Wed, 6 Jul 2011 12:37:30 +0200 Subject: Refactored analog to temp and temp to analog to not make distinction between hotend and bed. Changed both to return integers rather than floats. --- Sprinter/Sprinter.h | 29 ++++++++-- Sprinter/Sprinter.pde | 152 ++++++++++++++++---------------------------------- 2 files changed, 73 insertions(+), 108 deletions(-) (limited to 'Sprinter') diff --git a/Sprinter/Sprinter.h b/Sprinter/Sprinter.h index 4e3c7ea..1a324a0 100644 --- a/Sprinter/Sprinter.h +++ b/Sprinter/Sprinter.h @@ -8,10 +8,31 @@ void process_commands();
