* RCC: Add rcc_is_clk_on().Marti Bolivar2012-04-111-0/+9
| | | | | | This is a convenience function for checking if a clock line is on. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* RCC: Clean up and sanitize interfaces across F1, F2 series.Marti Bolivar2012-04-111-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Additions: - rcc_switch_sysclk(): For changing the clock used as SYSCLK's source. - enum rcc_clk: One for each system and secondary clock source (e.g. HSE, LSE). These are defined on a per-series basis in each of the <series/rcc.h>. - rcc_turn_on_clk(), rcc_turn_off_clk(), rcc_is_clk_ready(): For turning on system and secondary clock sources, and checking whether or not they're ready. Uses enum rcc_clk. Removals: - rcc_clk_init(): There's no way to port this to F2. Move it to the F1 header. This also means we can remove the empty implementation and enum rcc_pll_multiplier from the F2 RCC header, where it doesn't make any sense. Also fix up some includes, and rewrite rcc_clk_init() in terms of the new clock source management functions. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* RCC: Break out some portable functionality from stm32f1/.Marti Bolivar2012-04-111-0/+44
| | | | | | | | | | | | | Portions of rcc_clk_enable(), rcc_reset_dev(), and rcc_set_prescaler() are portable; break these into static inline helpers in rcc_private.h. These guts of these are portable, but the arrays of registers etc. are not. Also add an extern declaration for rcc_dev_table into rcc_private.h. This lets us put rcc_dev_clk() into a newly resurrected libmaple/rcc.c, since that's portable. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Move RCC support for STM32F1 to libmaple/stm32f1/.Marti Bolivar2012-04-111-206/+0
| | | | | | | | | | | | This is a backwards-compatible change. Modify libmaple/rules.mk to include the family's include directory. This allows libmaple/include/libmaple/rcc.h to include the STM32F1 RCC header with #include <family/rcc.h>. We'll use this convention henceforth to distinguish between top-level and family-specific headers. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* 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.

* 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

| | | | | | Older refactor commit e4807a5010f59ab863ad2c96dc14caf65bf1ae60 used bit-banding in rcc_clk_init() to set RCC_CR_HSEON, which doesn't work for some reason. Not going to try to figure out why.

| | | | | | | This is just a change of macro name with zero impact on the actual binary. Looking at page 87/1003 of the STM reference manual, bits [0:1] are the SW register which is modifiable by software, while [2:3] are SWS and are set only by hardware.
