* stm32f4: 32bit-float-friendly GCC flagsbnewbold2015-03-031-1/+2
| | | | | | | | | | | | | | This commit makes 'float' (32-bit) the default for floating point constants in the source code, instead of the defaults 'double' (64-bit). Floating point performance is very sensitive to the float vs. double distinction on 32-bit processors, especially Cortex-M4s with a VFP unit for floats but not doubles. In the future it may be wise to make this change for non-hard-fp chips (aka, all the other STM32s) as well, for behavioral consistancy. The warning flag ensures that the frequently used parts of the code base will be less ambiguous, but doesn't cover series-specific code.

* reset.py: Use the real print function (requires Python 2.6+).Marti Bolivar2012-06-281-14/+16
| | | | | | | | | | | | | | | | | | | | | | Use "from __future__ import print_function" so the recent py3k compatibility patches to reset.py preserve the old output in Python 2. This increases our minimum Python version to 2.6, but avoids ugly output Python 2, where print statements with a tuple argument print the tuple with parentheses etc. Python 2.6 came out almost four years ago, and it's widely available: - even on older Linux distros (e.g. Ubuntu 10.04 and Debian Squeeze have 2.6 default at time of writing), - on OS X since 10.6, - and Windows users will probably be installing from python.org anyway, so they've likely got a reasonably recent vintage. Dropping 2.5 support thus doesn't seem likely to cause problems. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

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 Bolivar2012-06-0743-368/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | As the number of boards increases, it's less practical to keep a list of them in the help target output (notice also that some have been forgotten).

| * Slightly improve and generify the USB infrastructure.Marti Bolivar2012-06-038-3/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever Doxygen is running on a series header, make it run an awk script, the Evil Mangler, that pretends the file is enclosed in an appropriate namespace declaration for the series target. Doxygen chokes if two structs have the same name. This is a problem for the series headers, which commonly have data structures with the same name. However, if those structs are in different namespaces, Doxygen has no problems. We obviously can't use namespaces in C headers, so use FILTER_PATTERNS to trick Doxygen into thinking they're there. Ugly, but I can't think of a better way to handle this. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
