C and C++ library for STM32 ARM Cortex-M3 development boards. https://git.suspectdevices.com/feurig/libmaplemidi-cma/atom?h=master 2012-04-11T20:56:50+00:00 2012-04-11T20:56:50+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-11-15T17:45:43+00:00 urn:sha1:954f9e5065b39fe4c683f4d216b54326d876f51b 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.

Instead of using the struct, their members were unpacked into the struct they were nested in. Additionally sizeof()'s were commented in favor of manual calculation of structure sizes. After uncommenting these changes, the USB CDC peripheral stopped correctly configuring with the host. The root problem with the structures is that GCC is padding them. By applying __attribute__((__packed__)), these problems are fixed. I removed all the instances of the workaround I saw within the USB code.

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 2011-03-11T21:24:44+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-03-07T18:11:54+00:00 urn:sha1:7c5c5bb118fe3eacbfdc0599214bd989d85d9741 2011-02-27T16:42:56+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-02-27T16:42:56+00:00 urn:sha1:d6ef63b47153b73050d497268583a2e224db6a67 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. 2010-12-15T21:16:31+00:00 Marti Bolivar mbolivar@mit.edu 2010-12-15T06:50:56+00:00 urn:sha1:88cb23747ef424d26e6fffc458b5ebfc678e4d9f 2010-09-27T04:40:44+00:00 Marti Bolivar mbolivar@mit.edu 2010-09-27T04:40:44+00:00 urn:sha1:753f89de354eff212d84f3f2aff41146865da342 2010-09-22T07:17:45+00:00 Perry Hung iperry@gmail.com 2010-09-22T07:17:45+00:00 urn:sha1:c13e850abe053edaa1aad6ef7b928c6bf9288cb3 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.

The driver is limited to synchronous, blocking sends and a 8-bit data frame format. Tested on SPI1 and SPI2. Other peripherals are temporarily disabled, and the rx function is untested until I find a good peripheral to test everything on. 2010-04-01T02:43:27+00:00 Perry Hung iperry@alum.mit.edu 2010-04-01T02:22:29+00:00 urn:sha1:87c85a6449385b1256e0c64bbf5369c4faf9746d Relicensed the bulk of libmaple under the more permissive MIT License, from GPLv3.
