* stm32f1: Resurrect DMA support. (sets up breaking change)Marti Bolivar2012-05-031-335/+3
| | | | | | | | | | | | | | | | | Breaking change set up: struct dma_handler_config is no longer part of the public API in <libmaple/dma.h>. User code which was touching these was always mistaken; it should be using dma_attach_interrupt() or dma_detach_interrupt() instead. Other than that, just move the nonportable bits in <libmaple/dma.h> and libmaple/dma.c to the appropriate places under libmaple/stm32f1/. (Ouch. This is almost everything.) Patch the (new) STM32F1 <series/dma.h> here and there to make everything compile; this is mostly limited to forward-declaring struct dma_dev and providing a hack _dma_dev_regs() declaration so inline functions in the series header can still access a device's registers.

* Move public headers to include directories; related cleanups.Marti Bolivar2012-04-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* DMA: Fix non-working DMA interrupts.Marti Bolivar2011-06-201-7/+7
| | | | | | | | | | | | | | | | | | | | | | libmaple/dma.c defines DMA interrupts __irq_dma_channel[1-7], consistent with what is specified by support/ld/names.inc. However, names.inc is inconsistent with what support/ld/libcs3_stm32_src/ expects. Specifically, it contradicts the files - support/ld/libcs3_stm32_src/stm32_isrs.S - support/ld/libcs3_stm32_src/stm32_vector_table.S Which use the names __irq_dma1_channel[1-7]. Change names.inc and dma.c to use the correct IRQ names. The original names.inc/libcs3_stm32_src inconsistency was introduced in 43d6921658cd29b8022af4424d340a90fbcb9a7f, but dma.c had the correct names until ec3cf2903f4b03bc1dae5e159495c9e5ef0938ca, where they were renamed for consistency with names.inc. At that point, DMA interrupts stopped working. (This was documented in the commit message). Thanks to forum user robodude666 for tracking this down.
* 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

| | | | | | Simple USART receiver to SRAM buffer demo partially working. Interrupting when buffer is full fails mysteriously. GDB thinks we ended up in an STM32 reserved exception.

| | | | renamed SysTick_Handler back to SysTickHandler since all of our linker magic/lanchon-stm32 depends on that name. added backup register support in order to test independent watchdog support; it seems to work. next major test target is DMA support.
