libmaple takes orders, it doesn't give them. Signed-off-by: Marti Bolivar

Fix a bunch of Doxygen file-level comments.

2012-05-08T20:22:41+00:00

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.

2012-04-11T20:56:50+00:00

Move libmaple/*.h to (new) libmaple/include/libmaple/. The new accepted way to include a libmaple header foo.h is with: #include 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 . - 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 . 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 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.

syscalls.c: Allow environment to specify heap boundaries.

2011-09-13T00:59:12+00:00

Rename HEAP_START/HEAP_END macros CONFIG_HEAP_START/CONFIG_HEAP_END, to mark them as build-time configuration options. Wrap their definitions with #ifndefs appropriately.

[support/ld] Add linker support for reconfigurable heap.

2011-09-12T21:25:01+00:00

- common_header.inc: Declare EXTERN symbols _lm_heap_start and _lm_heap_end. - common_rom.inc: Check for _lm_heap_start and _lm_heap_end. If they are defined, preserve their values. Otherwise, _lm_heap_start is starts after .bss, and _lm_heap_end is the end of SRAM. This allows existing linker scripts to continue using the old heap scheme, but allows for customizability elsewhere. - syscalls.c: Respect the addresses of _lm_heap_start and _lm_heap_end as the boundaries of the heap in _sbrk().

syscalls.c: Bugfix _sbrk() implementation.

2011-09-08T03:34:24+00:00

Fix _sbrk() implementation so it properly rejects negative arguments which would send the program break below the heap start. Fix incorrect check against argument causing heap overflow. Also set errno properly to ENOMEM when the call fails. Beginning and end of the heap are now determined by HEAP_START and HEAP_END macros. Their current values seem to work OK for heaps on the internal SRAM, but they'll need to get generalized for Maple Native.

syscalls.c: Remove fictitious uart_send() and broken comments.

2011-09-08T03:34:23+00:00

uart_send() is not part of libmaple, and nm doesn't show it getting linked in from anywhere else, so I don't believe it exists. Remove it. Also remove some commented-out sections from getch(), putch(), _write(), and fgets(). These either reference uart_send() or use old libmaple APIs which no longer exist.

Keep it 80-column clean.

2011-06-07T18:44:39+00:00

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
