Files for each peripheral (examples given for STM32 GPIO)
|
|
---------------------------------------------------------
|
|
|
|
In include/libopencm3/stm32.
|
|
A "dispatch" header to point to the subfamily header (gpio.h)
|
|
|
|
In include/libopencm3/stm32/f*
|
|
A file with defines that are specific to the subfamily, and an include of
|
|
needed common header files (gpio.h).
|
|
|
|
In include/libopencm3/stm32/common
|
|
A file with defines common to all subfamilies. Includes the cm3 common header
|
|
(gpio_common_all.h).
|
|
|
|
In include/libopencm3/stm32/common
|
|
May be one other file with defines common to a subgroup of devices.
|
|
This includes the file common to all (gpio_common_f24.h).
|
|
|
|
In lib/stm32/f*
|
|
A file with functions specific to the subfamily. Includes the "dispatch" header
|
|
and any common headers needed (gpio.c).
|
|
|
|
In lib/stm32/common
|
|
Has functions common to all subfamilies. Includes the "dispatch" header
|
|
(gpio_common_all.c).
|
|
|
|
In lib/stm32/common
|
|
May be one other file with functions common to a group of subfamilies. Includes
|
|
the "dispatch" header and the file common to all (gpio_common_f24.h).
|
|
|
|
Makefiles in lib/stm32/f? have the common object files added and the
|
|
common directory added to VPATH.
|
|
|
|
NOTE: The common source files MUST have the "dispatch" header so that
|
|
compilation will use the specific defines for the subfamily being compiled.
|
|
These can differ between subfamilies.
|
|
|
|
NOTE: The common source files must have a line of the form
|
|
|
|
#ifdef LIBOPENCM3_xxx_H
|
|
|
|
where xxx is the associated peripheral name. This prevents the common files
|
|
from being included accidentally into a user's application. This however
|
|
causes doxygen to skip processing of the remainder of the file. Thus a
|
|
|
|
@cond ... @endcond
|
|
|
|
directive must be placed around the statement to prevent doxygen from
|
|
processing it. This works only for doxygen 1.8.4 or later. At the present
|
|
time most distros have an earlier buggy version.

Documentation
|
|
-------------
|
|
|
|
In include/libopencm3/stm32/f*
|
|
A file doc-stm32f*.h contains a definition of the particular family grouping.
|
|
This grouping will appear in the main index of the resulting document with all
|
|
documentation under it.
|
|
|
|
All header files for a peripheral (common or otherwise) will subgroup under a
|
|
name which is the same in all families (such as gpio_defines). The peripheral
|
|
header file in include/libopencm3/stm32/f* will then include this group as a
|
|
subgroup under the specific family group. Doxygen is run separately for each
|
|
family so there is no danger of accidentally including the wrong stuff.
|
|
|
|
Similarly for the source files for a peripheral which will subgroup under a
|
|
same name (such as gpio_files). The peripheral source file in lib/stm32/f*
|
|
will include this as a subgroup under the specific family group.
|
|
|
|
DOXYFILE for a particular family will list the family specific and common files
|
|
(headers and source) that are to be included. The result (in the long run) will
|
|
be that all peripherals will appear under the same family grouping in the
|
|
documentation, even if they are identical over a number of families. That is
|
|
probably most useful to end users who only need to see the documentation for
|
|
one family.
