Rewrite existing IRQ handlers in terms of new functions
dispatch_single_exti() and dispatch_extis(). dispatch_single_exti()
handles EXTIs which have a dedicated IRQ line, and thus doesn't have
to check EXTI_PR; it is mostly equivalent to the (now removed)
handle_exti(). dispatch_extis() handles multiple EXTIs sharing an IRQ
line. Using dispatch_extis() instead of calling handle_exti()
multiple times avoids unnecessary I/O to the (volatile) EXTI_BASE->PR
register.
These changes are in the flavor of the timer IRQ optimizations
performed in f5016b15bef56bbdfd187f9b623177ef6dde7ace.

These functions incorrectly replicate functionality that is already
accomplished by manipulating EXTI_IMR directly.

Add new handle_exti() instead of calling clear_pending() and
dispatch_handler() each time.

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.

libraries for libcs3.

Some bugfixes in the external interrupt code were found along the way.
Defines for nonexistent registers removed from nvic interface.

Extend the wirish attachInterrupt() and detachInterrupt() interface to
work with all GPIOs.
Note: The STM32 external interrupt lines are multiplexed between GPIO
ports. While any GPIO can be used as an external interrupt, not all of
them can be used at the same time. Each EXTI[n] line selects between
PA[n], PB[n], PC[n], etc. For example, line EXTI5 can be used with STM32
pins PA5, PB5, or PC5, but not all at the same time. See table:

Relicensed the bulk of libmaple under the more permissive MIT License,
from GPLv3. Files that were largely or entirely derived from
the Arduino, STM, or Lanchon retain their original licenses.

Removed inttypes.h from libmaple. Will have another pass through to use
the standard libmaple types, but will come in another commit.
|
|
|
copy-to-ide and Makefile updated to conform; .gitignore added;
LICENSE added
