-Fix clock calculations for fast-mode support
-Add I2C_REMAP option to remap i2c1 (untested)
-Add I2C_BUS_RESET option to reset bus on initialization
-Add optional timeout parameter
-Doxygen comments
-Various cleanup
10-bit slave addressing is untested until I have a device that speaks
such.

This merges the libmaple refactor work into master. The contents of
libmaple proper (/libmaple/) are almost completely incompatible with
previous APIs in master. See /docs/source/libmaple/overview.rst for
more information on the new design.
Wirish incompatibilities are limited to the HardwareTimer class;
however, there are several new deprecations, most likely to be removed
in 0.1.0.

This brings util.h down to some bit manipulation macros, failure
routines, and asserts.

HardwareTimer was removed from the build when the timer refactor was
done; this redoes it in terms of the new timer.h interface. A variety
of conflicting or badly designed bits were deprecated or removed.
I'm still not satisfied with this interface, as it's going to make
life difficult moving forward to high-density chips, where the
addition of basic timers means that the capture/compare methods won't
apply in some cases. However, we need to get 0.0.10 out the door, so
it'll have to do for now.
The docs are up to date, and contain a warning that the Wirish API
isn't stable and a recommendation to use libmaple proper.

Fixing some Sphinx error messages.

Done for consistency the rest of the source. Doesn't affect any
documented features.

It would be nice to have something like a timer_set_period() in
libmaple proper that takes the period and the clock rate as
parameters, much the same as usart_set_baud_rate() does. No time for
that now, though, so punt to 0.1.0.

Got rid of native_sram.h (and native_sram.cpp), and pushed their
functionality into maple_native.cpp. Fixed includes in maple_native.h.
Fixed includes in fsmc.h.

Still a polling driver, but the libmaple proper interface exposes
enough that users enable the various interrupts and define their own
IRQ handlers if they feel like it.
Wirish HardwareSPI interface was largely redone; it's more like the
Arduino implementation now, although there are some differences when I
didn't like their API. The old methods are still there, but are
deprecated and slated for deletion in 0.1.0.
New board-specific values: BOARD_NR_SPI, BOARD_SPIx_NSS_PIN,
BOARD_SPIx_MOSI_PIN, BOARD_SPIx_MISO_PIN, and BOARD_SPIx_SCK_PIN, for
x from 1 to BOARD_NR_SPI.
Documentation was updated appropriately.

The vast majority of the Maple-specific values have been pulled out of
the higher-level overview pages and replaced with refs into documents
under /docs/source/hardware/.
Much of the work that's left to be done in this regard is labeled with
versioned TODO and FIXME comments.
Suggestions from StephenFromNYC and gbulmer were incorporated from

- gpio.h: afio_mapr_swj_config() renamed afio_cfg_debug_ports()
- [new] wirish_debug.h: disableDebugPorts(), enableDebugPorts()
- Maple, Maple Native, and Maple RET6 PIN_MAPs are now larger by 5,
have mappings for the extra JTAG/SW pins.
Documentation was updated appropriately.

No corrections made to the pin definitions themselves.
|
| |
| |
| |
| | |
Blocking fixes for 0.0.10; other changes.
|
| | |
|

| |

Other USART transmission functions are still blocking, but are now
implemented in terms of usart_tx().
|

Added i2c_init() for consistency with rest of libmaple.
|
| |
| |
| |
| |
| | |
Merging in the standalone refactor docs, etc. The individual libmaple
API pages are going to need to get redone.
|
| | |
|

License header made 80-column clean. usart_irq() comment for the
USART_SAFE_INSERT case made easier to understand.

Folded information in the README about the library Makefile target
into docs/source/unix-toolchain.rst. Added a pointer to the JTAG
HOWTO page on the wiki. Made some other miscellaneous cleanups,
updates and improvements.
