From 5b8953124e8c00cdf05169de6e304834cefacf63 Mon Sep 17 00:00:00 2001 From: Ken Sarkies Date: Sat, 9 Mar 2013 14:39:01 +1030 Subject: This mainly moves the STM32 timers' code to the common area. F2 and F4 have a common section to deal with the options register (TIM2 and TIM5 only) L1 has been made common with timer_common_all as its options register has very different settings to F2/F4. Code is in the L1/timer.c L1/timer.h files Note that F3 and F05 timers should fit into this scheme, with F3 having additional features. Bundled with this is L1/pwr.h to change a documentation setting Also all the Doxyfiles have added "ENABLE_PREPROCESSING = NO" to fix a problem introduced by commit 118. --- lib/stm32/common/timer_common_f24.c | 51 +++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 lib/stm32/common/timer_common_f24.c (limited to 'lib/stm32/common/timer_common_f24.c') diff --git a/lib/stm32/common/timer_common_f24.c b/lib/stm32/common/timer_common_f24.c new file mode 100644 index 0000000..4dd7c08 --- /dev/null +++ b/lib/stm32/common/timer_common_f24.c @@ -0,0 +1,51 @@ +/** @addtogroup timer_file + +*/ + +/* + * This file is part of the libopencm3 project. + * + * Copyright (C) 2010 Edward Cheeseman + * Copyright (C) 2011 Stephen Caudle + * + * This library is free software: you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
