* Fix a bunch of Doxygen file-level comments.Marti Bolivar2012-05-081-1/+1
| | | | | | | | | | | | | Fix @file in many places. Also fix up the descriptions where it's appropriate. This standardizes the @file formatting across the library to explicitly include any parent directories up to the repository root. Besides being nice, this will hopefully let us manage Doxygen's XML output so as to make extracting series-specific pieces via Breathe in the leaflabs-docs repo possible.

* Move public headers to include directories; related cleanups.Marti Bolivar2012-04-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move libmaple/*.h to (new) libmaple/include/libmaple/. The new accepted way to include a libmaple header foo.h is with: #include <libmaple/foo.h> This is more polite in terms of the include namespace. It also allows us to e.g. implement the Arduino SPI library at all (which has header SPI.h; providing it was previously impossible on case-insensitive filesystems due to libmaple's spi.h). Similarly for Wirish. The old include style (#include "header.h") is now deprecated. libmaple/*.h: - Change include guard #defines from _FOO_H_ to _LIBMAPLE_FOO_H_. - Add license headers where they're missing - Add conditional extern "C" { ... } blocks where they're missing (they aren't always necessary, but we might was well do it against the future, while we're at it.). - Change includes from #include "foo.h" to #include <libmaple/foo.h>. - Move includes after extern "C". - Remove extra trailing newlines Note that this doesn't include the headers under libmaple/usb/ or libmaple/usb/usb_lib. These will get fixed later. libmaple/*.c: - Change includes from #include "foo.h" to #include <libmaple/foo.h>. Makefile: - Add I$(LIBMAPLE_PATH)/include/libmaple to GLOBAL_FLAGS. This allows for users (including Wirish) to migrate their code, but should go away ASAP, since it slows down compilation. Wirish: - Move wirish/**/*.h to (new) wirish/include/wirish/. This ignores the USB headers, which, as usual, are getting handled after everything else. - Similarly generify wirish/boards/ structure. For each supported board "foo", move wirish/boards/foo.h and wirish/boards/foo.cpp to wirish/boards/foo/include/board/board.h and wirish/boards/foo/board.cpp, respectively. Also remove the #ifdef hacks around the .cpp files. - wirish/rules.mk: put wirish/boards/foo/include in the include path (and add wirish/boards/foo/board.cpp to the list of sources to be compiled). This allows saying: #include <board/board.h> instead of the hack currently in place. We can allow the user to override this setting later to make adding custom board definitions easier. - Disable -Werror in libmaple/rules.mk, as the current USB warnings don't let the olimex_stm32_h103 board compile. We can re-enable -Werror once we've moved the board-specific bits out of libmaple proper. libraries, examples: - Update includes accordingly. - Miscellaneous cosmetic fixups.

* exti.c: Optimize multiplexed IRQ handlers.Marti Bolivar2011-08-031-43/+48
| | | | | | | | | | | | | | Rewrite existing IRQ handlers in terms of new functions dispatch_single_exti() and dispatch_extis(). dispatch_single_exti() handles EXTIs which have a dedicated IRQ line, and thus doesn't have to check EXTI_PR; it is mostly equivalent to the (now removed) handle_exti(). dispatch_extis() handles multiple EXTIs sharing an IRQ line. Using dispatch_extis() instead of calling handle_exti() multiple times avoids unnecessary I/O to the (volatile) EXTI_BASE->PR register. These changes are in the flavor of the timer IRQ optimizations performed in f5016b15bef56bbdfd187f9b623177ef6dde7ace.

* exti.c: Cleanups.Marti Bolivar2011-08-031-21/+18
| | | | | Add new handle_exti() instead of calling clear_pending() and dispatch_handler() each time.
* Keep it 80-column clean.Marti Bolivar2011-06-071-14/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Go through overlong source code lines and convert as many of them as appropriate to be 80-column clean. This mostly affects license headers. Overlong lines are determined by running following from the libmaple base directory: $ ack-grep --nocolor --nogroup --cpp --cc --ignore-dir=usb -- '.{80}' Note that this excludes libmaple's usb subdirectory, which is still full of ST code that doesn't follow the libmaple source code guidelines. Contents of ~/.ackrc (these won't matter, but are included for completeness): --ignore-dir=docs --ignore-dir=build --type-set ld=.ld --type-set rst=.rst --type-set txt=.txt --type-set mk=.mk

* Enable external interrupts on all Maple GPIOs.Perry Hung2010-09-221-155/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the wirish attachInterrupt() and detachInterrupt() interface to work with all GPIOs. Note: The STM32 external interrupt lines are multiplexed between GPIO ports. While any GPIO can be used as an external interrupt, not all of them can be used at the same time. Each EXTI[n] line selects between PA[n], PB[n], PC[n], etc. For example, line EXTI5 can be used with STM32 pins PA5, PB5, or PC5, but not all at the same time. See table: EXTI Line Maple Pin STM32 Pin 0 D2 PA0 0 D27 PB0 0 D15 PC0 1 D3 PA1 1 D28 PB1 1 D16 PC1 2 D1 PA2 2 D17 PC2 2 D25 PD2 3 D0 PA3 3 D18 PC3 4 D10 PA4 4 D19 PC4 5 D13 PA5 5 D4 PB5 5 D20 PC5 6 D12 PA6 6 D5 PB6 6 D35 PC6 7 D11 PA7 7 D9 PB7 7 D36 PC7 8 D6 PA8 8 D14 PB8 8 D37 PC8 9 D7 PA9 9 D24 PB9 9 D38 PC9 (BUT) 10 D8 PA10 10 D29 PB10 10 D26 PC10 11 D30 PB11 12 D31 PB12 13 D32 PB13 13 D21 PC13 14 D33 PB14 14 D22 PC14 15 D34 PB15 15 D23 PC15
* Licensing: Relicensed libmaple under the MIT License.Perry Hung2010-03-311-12/+18

| | | | | Removed inttypes.h from libmaple. Will have another pass through to use the standard libmaple types, but will come in another commit.
