Adding this attribute allows to avoid warnings issued by GCC in cases
when 'scb_reset_system' is used as a last call in a function with
"noreturn" attribute set(usually reset handler of some sorts)
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.
(prevents inclusion and also issues warning)
Changes to some source files to remove references to common headers.
Changes to rng.h to make guard symbols the same in f2 and f4.
to remove errors, duplications and inconsistencies.
File lib/stm32/f1/pwr.c - all code removed as it duplicates that in common/pwr_common.c
Remaining changes do not affect code. Compiles OK.
TODO efm32 has no code so generates no modules
TODO F2 needs pwr.c
TODO L1 needs dma.h and dma.c
Clearing a single bit in DMA_CCR, then immediately writing a 0 over the
entire register is completely redundant on the F1, F3 and L1 DMA
peripherals. (Unlike the F2 & F4 DMA Peripheral, where this is
required)
Add an example using the RTC to help with a lower power design. This is
a sister example to the existing "button-irq-printf", which is
functionally identical, but uses far less power.
There's more tricks that can be done to lower the power even further,
but this shows a few of the early steps that can be done, using the RTC
wakeup instead of a timer.
Add the register definitions and some of the most basic helper functions
for the new style BCD RTC module found on the F2, F4, L1, F3 and F0.
This tries to keep as close to HACKING_COMMON_DOC as possible, while
maintaining sane names.
Code added for L1 to support the PWR Control block didn't properly
follow the HACKING_COMMON_DOC guidelines. The naming was wrong, and
some headers were missing. This commit has no functional changes, it
only addresses the style and structure problems.
Earlier additions to the L1 support were not correctly using linux
coding guidelines as specified in /HACKING.
Some examples were also missing license information.
Fixes#51
There should be no reason for manually trying to load the stack. Cortex
devices can be programmed with only C, and any code that needed this
would indicate broken vectors.
the "make clean" target showed a constant "stm32/f1" debug message
instead of the current relative directory. this is fixed by showing the
relevant portion of the current directory instead, relevant being
determined by evaluating the current makefile's relative position and
stripping that part off.
Add an abstraction layer to handle the clock control for the run time clock on
LM4F (RCC). Sleep and deep-sleep clock configuration is not handled.
Complete documentation for the clock control API is included in doxygen-style
comments, and is included in [doc].
