* Fixups for Wire library builds.Marti Bolivar2012-08-311-0/+2
| | | | | | | | | Add libraries directory to global include path, so Wire sub-headers can be included in a directory-independent way. Tweak Wire global declaration and definition so it builds. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Makefile: Don't assume Cortex M3.Marti Bolivar2012-08-051-4/+3
| | | | | | | | | Instead, derive -march and -mcpu from the target MCU in target-config.mk. Also (on STM32F4) add the necessary floating point flags. The CodeSourcery toolchains don't support these, so we'll need to prepare alternative toolchains when F4 support is official. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| | | | | | | | | We'll need to mess with the linker flags to add support for ARM toolchains other than CodeSourcery's. Since the toolchain is determined in build-rules.mk, decisions that depend on it have to happen after it's included. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge the long-lived (too long; future changes like these will need to proceed more incrementally) development branch of libmaple, containing experimental STM32F2 and STM32F1 value line support, into master. This required many changes to the structure of the library. The most important structural reorganizations occurred in: - 954f9e5: moves public headers to include directories - 3efa313: uses "series" instead of "family" - c0d60e3: adds board files to the build system, to make it easier to add new boards - 096d86c: adds build logic for targeting different STM32 series (e.g. STM32F1, STM32F2) This last commit in particular (096d86c) is the basis for the repartitioning of libmaple into portable sections, which work on all supported MCUs, and nonportable sections, which are segregated into separate directories and contain all series-specific code. Moving existing STM32F1-only code into libmaple/stm32f1 and wirish/stm32f1, along with adding equivalents under .../stm32f2 directories, was the principal project of this branch. Important API changes occur in several places. Existing code is still expected to work on STM32F1 targets, but there have been many deprecations. A detailed changelog explaining the situation needs to be prepared. F2 and F1 value line support is not complete; the merge is proceeding prematurely in this respect. We've been getting more libmaple patches from the community lately, and I'm worried that the merge conflicts with the old tree structure will become painful to manage.

| * Rework linker scripts.Marti Bolivar2012-06-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having separate linker scripts for all the boards is a bad idea. Most boards really only need to specify MEMORY and the appropriate REGION_ALIASES() so that support/ld/common.inc can do its work. Not having infrastructure for this leads to duplication -- viz. the Maple Mini linker scripts are identical to the Maple's, and the olimex_stm32_h103 linker directory is just a symlink to Maple's. Clearly, the current structure is wrong. To fix it, instead of having per-board subdirectories of support/ld/, add per-MEMORY subdirectories of (new) support/ld/stm32/mem/. The per-board .mk files under support/mk/board-includes/ now reference these directly, and target-config.mk and the Makefile handle this appropriately. We move some other stuff around in target-config.mk to make this all more convenient, and even allow more overriding of the libmaple defaults on a per-board basis. Custom board hacks will be easier now. Unfortunately, lots of duplication under support/ld/stm32/mem/ is necessary, as the LENGTH attribute in a MEMORY region specification doesn't support arithmetic expressions, and ld doesn't seem to have any way to specify MEMORY at the command line (why?!). If we find a better way than this, we should do it. If a board (e.g. Maple Native) _does_ really need special memory-related configuration, you can always put a per-board subdirectory of support/ld/stm32/mem. We do this here to configure the heap.

| * Slightly improve and generify the USB infrastructure.Marti Bolivar2012-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The good news is that <libmaple/usb.h> and <libmaple/usb_cdcacm.h> did turn out generic enough in what they specify to go on unchanged. However, we can't just go on assuming that there's USB just because we're on an F1. Now that there's value line in the tree, we need to be more careful (value line F1s don't have USB peripherals). To that end, make all the F1 board-includes/*.mk files specify what line their MCU is with an MCU_F1_LINE variable. Use that to hack libmaple/usb/rules.mk so we only try to build the USB module under appropriate circumstances. While we're at it, add a vector_symbols.inc for value line MCUs under support/ld/. We need this to get the target-config.mk modifications implied by the addition of MCU_F1_LINE. We'll fix up some other performance-line-isms under libmaple/stm32f1 in a separate commit. Also in libmaple/usb/: - Move everything into a new stm32f1 directory. Due to aforementioned rules.mk hacks, there is no immediate need for an stm32f2 directory (USB support doesn't exist there). - Update the README for style and content.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is for greater consistency with the ST application notes, which refer to migrating "across" series (e.g. F1 to F2), but compatibility "within" a family (e.g. F1). So: - Move libmaple/stm32x/include/family to .../include/series/ and fix up includes appropriately. - Refer to "family" headers as "series" headers in comments. - Make similar "find and replace"-style changes to build system variable names and comments. - Move support/ld/stm32/family to .../stm32/series.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add libmaple/usb/rules.mk, which compiles the USB FS device firmware submodule. Move the logic for compiling the USB stack from libmaple/rules.mk into libmaple/usb/rules.mk. Move libmaple/usb/usb_cdacm.h to libmaple/include/libmaple/. Its API is sufficiently general that we'll be able to port it over to USB OTG (either FS or HS) eventually, and that lets us include it from Wirish using the new style for libmaple headers.

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.

|/ | | | | | | | | | | | | | | | | | | | | | | It's very annoying to have to build libmaple projects in-tree. Users are just copying the repository everywhere. That's stupid. So I made this: https://github.com/mbolivar/example-libmaple-project It needs these patches to work. Add a header and footer for rules.mk files, so we can change them around and things will continue to work for the users, who just include them. In Makefile, add USER_MODULES to LIBMAPLE_MODULES if it's nonempty. This is the hook you use to get your code compiled and linked correctly. Hack build-targets.mk for stupid reasons I hope to fix later. For now, you'll need an empty main.cpp in BOTH the libmaple directory and your directory if you want things to work the way you'd expect.

* Remove CS3-style initialization.Marti Bolivar2012-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove libcs3-related bits from support/ld. Break them out into libmaple proper and Wirish as appropriate: vector table definition and ISR declarations go into libmaple proper, and startup code goes into Wirish. Vector table symbols are included into common.inc from an STM32 family-specific directory under support/ld/stm32. This is a combination of 5 commits. Individual commit messages follow: libcs3_stm32_src: Don't depend on cs3.h. So we can use the existing toolchain. Move ISR decls/vector table into libmaple proper. This allows us to configure the vector table on a per-family basis. - Move support/ld/libcs3_stm32_src/stm32_isrs.S stm32_vector_table.S to libmaple/stm32f1/isrs_performance.S vector_table_performance.S, respectively. The directory libmaple/stm32f1/ is intended to hold all STM32F1-specific code within libmaple. Obviously, there's a lot of work to do before this becomes true. - support/ld/libcs3_stm32_src/Makefile: Don't try to compile stm32_isrs.S and stm32_vector_table.S anymore. - Add libmaple/stm32f1/rules.mk to include these new files in the standard libmaple build. - support/make/target-config.mk: Add LIBMAPLE_MODULE_FAMILY, which selects a directory to use as a family-specific libmaple submodule. - Makefile: Add LIBMAPLE_MODULE_FAMILY to LIBMAPLE_MODULES. Remove support/ld/libcs3_stm32_src and derived object files. From support/ld/libcs3_stm32_src, move start.S and start_c.c into Wirish. Modify wirish/rules.mk accordingly. Delete support/ld/libcs3_stm32_*_density.a. These are no longer necessary, as the relevant objects are included in the standard Wirish build. Remove the GROUP statements from the board linker scripts accordingly. Remove SEARCH_DIR(.) from common.inc; it's no longer necessary. Also fix up some comments that are now out of date. wirish/start_c.c: Don't use CS3-style memory initialization. Switch memory initialization to a simpler style of initializing .data if necessary, then zeroing .bss. Initializing .data is only necessary during Flash builds, since during RAM builds, LOADADDR(.data) == ADDR(.data). This makes libmaple completely incompatible with the CS3 startup sequence. Subsequent commits will clean up the namespace to reflect that fact. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Make vector table symbols family-specific during linking.Marti Bolivar2011-11-151-1/+1
| | | | | | | | | | | | | | | | | - support/make/target-config.mk: add LD_FAMILY_PATH, the directory to search for STM32 family-specific link configuration files. For now, this is just a stub which points to support/ld/stm32/f1/performance, since that's all we currently support. We can add the logic to support different STM32 families here later. - Makefile: Pass -L $(LD_FAMILY_PATH) to linker. - Rename support/ld/names.inc to support/ld/stm32/f1/performance/vector_symbols.inc. - common.inc: INCLUDE vector_symbols.inc instead of names.inc.

* Make it easier to use the libmaple build system externally.Marti Bolivar2011-09-141-1/+7
| | | | | | | | | | | | | | It's been tricky for users to start their own projects while still using our build system. The current recommended practice to get this done involves modifying the top-level Makefile to add their module into LIBMAPLE_MODULES, and include their own rules.mk. Editing the repository Makefile is stupid and shouldn't be a necessary step. Instead of that, allow the environment to provide the initial value for LIBMAPLE_MODULES. This allows users to specify it on the command line. Also add WIRISH_PATH to the initial set of "useful" paths.

Servo is implemented in terms of HardwareTimer, so it also has been temporarily removed from the build. pwmWrite() likely got a little bit less inefficient due to indirection, but the PIN_MAPs shrank by a pointer per PinMapping.

| | | | | | | | | | | | | | | | | | | 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.
