* HardwareTimer.cpp: save some space with an rcc_clk_id hack.Marti Bolivar2012-06-031-97/+26
| | | | | | | | | | | | Since rcc_clk_ids for a peripheral now form a contiguous range by peripheral number, we can infer the rcc_clk_id for a timer given its number (e.g., can calculate RCC_TIMER2 given timerNum == 2). This lets us use timer_foreach() to avoid keeping a table of available timers in HardwareTimer.cpp. The implementation is hackish, but can be fixed up later if need be.

* Bring back HardwareTimer.Marti Bolivar2012-06-011-21/+102
| | | | | | | | | | | | | | Untested, but the timers work on F2 (see exampes/test-timers.cpp), so I'm hoping this is mostly OK. Note that there's an issue with TIMER2 and TIMER5 on F2: these timers have 32-bit counters, and the HardwareTimer methods are all based on uint16 (like on F1). I'm sorely tempted to keep this as-is; exposing the extra bits is just extra documentation, and the HardwareTimer interface is already way too complicated. The interface should still _work_; it just hides the fact that you're missing out on the extra bits for some of the timers. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Move public headers to include directories; related cleanups.Marti Bolivar2012-04-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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
* Getting rid of the last 0.0.10 TODO.Marti Bolivar2011-05-231-1/+0

* Putting updated HardwareTimer back into the build.Marti Bolivar2011-05-061-148/+69
| | | | | | | | | | | | | | | HardwareTimer was removed from the build when the timer refactor was done; this redoes it in terms of the new timer.h interface. A variety of conflicting or badly designed bits were deprecated or removed. I'm still not satisfied with this interface, as it's going to make life difficult moving forward to high-density chips, where the addition of basic timers means that the capture/compare methods won't apply in some cases. However, we need to get 0.0.10 out the door, so it'll have to do for now. The docs are up to date, and contain a warning that the Wirish API isn't stable and a recommendation to use libmaple proper.

* Cleaned out libmaple.h; this had wide-ranging implications.Marti Bolivar2011-02-271-2/+2
| | | | | | | | | | | | | | | | | | | Many of the #defines in libmaple.h were board-specific, not MCU-specific. Most of these were only used by code under libmaple/usb/. These were moved into usb_config.h, and are clearly marked as being terrible hacks. I'm going to treat the USB stack as a black box that we'll deal with later. Further, instead of having a variety of #defines like "How many USARTS do I have?", we decide that based on the density of the chip. This is determined by testing for STM32_MEDIUM_DENSITY or STM32_HIGH_DENSITY defines. libmaple currently doesn't support low-density chips, so that suffices. The Makefile will set these automatically based on the MCU. Other offending #defines are ERROR_LED_PORT and ERROR_LED_PIN; these were made optional, but they're set in the Makefile as a hack to keep things working.
