Updated the documentation so that it appears in all families
Also added it to the L1 area, but is untested. An addition to the memorymap
allows commonality and a #ifdef added to the spi_common_all code to
exclude the case of SPI3 for L1 and F0 as SPI3 doesn't exist in those.
An rcc dispatch header was added to remove same code from the spi header.
In the header:
- Fix DMA_SxCR_CT: change shift from 18 to 19
For use with the convenience functions:
- Added DMA_SxCR_CHSEL generic values
- Added DMA_STREAM - generic values
- Added dma_if_offset - rather than separating out LISR and HISR
- Added masks
- Added dma_disable_double_buffer_mode()
these register definitions are common to all cortex mcus. some of the
registers might not be implemented everywhere (especially the floating
point registers), but defining them does no harm.
this modification does not result in any changes in the example
binaries.
Conflicts:
lib/lm3s/vector.c -- split out to lm3s/irq.h
lib/stm32/f4/vector.c -- put the floating point initialization code into a function like in lpc43xx
the cortex generic interrupts get moved to lib/cm3/vector.c, the
platorms' individual irq names, initialization and handler prototypes go
to platoform specific irq.h files.
as the vector.c file heavily depends on platoform specific headers, it
can't be built once-and-for-all in lib/cm3/, so there are inclusion
stubs in the various architecture dirs; this might be better solved with
Makefile / include path handling.
one particular file is lib/lpc43xx/vector.c; that platform's
initialization code contains an additional section to copy everything
from flash to ram (which probably performs better there). that code
still resides in the inclusion stub, and gets mashed in using defines.
would need a cleaner implementation together with the Makefile solution.
this commit contains some files of the upcoming efm32 branch, from which
it was cherry-picked.
the .bin files produced from before and after this commit only differ in
lpc43xx, where the startup sequence was subtly modified.
New doc directory with config files and generated html, LaTeX/pdf.
Makefile provided for autogeneration and explanatory README.
The project structure is hostile to doxygen, which can't cope with functions
of the same name. Doxygen is run for each family separately, and separately
for LaTeX generation. Customized layout files sort of "integrate" HTML, and
separate pdfs are generated for each family. Not ideal but seems the best
solution until doxygen changes, if at all.
This was also fixed in ac29b654a992a4855626fc0b92874d3847914f85 in a
different way. I think the mask definition should be left with 1s
indicating the bits of interest.
This reverts commit e11185d47d0a2fea6d2782761edd5fd489541512.
- Rename SPI_CR2_FRF_TI to SPI_CR2_FRF_TI_MODE to match datasheet.
- Rename SPI_CR2_FRF_MOTOROLA to SPI_CR2_FRF_MOTOROLA_MODE (see above).
- Fix SPI_CR2_FRF_MOTOROLA_MODE bit definition, must be (0 << 4).
- Change SPI_SR_RXNE to SPI_SR_TIFRFE; this was probably a copy-paste
error. Also, the bit definition is (1 << 8).
