Bug fixes include:
- keep interrupts disabled during lpm_sleep() so that we don't
miss any interrupts we may have been expecting
- check that the pending etimer isn't already expired (and don't sleep
at all if it is)
- check that the about-to-be scheduled rtimer wakeup is neither too
far into the future nor too close into the future (or even in the
past) before actually setting the interrupt (should fix#1509); If
the time is out of bounds we use a default min or max value instead.
- Correctly handle LPM_MODE_MAX_SUPPORTED set to zero (and added a
macro for the zero value) so that sleeping can be disabled altogether
- If no etimer is set, we specify a wakeup time which is reasonably far
into the future instead of setting none at all (this will save on
power consumption whenever no etimers are set).
Also did a bit of refactoring in that some long functions were broken
into multiple functions.
Otherwise a crash results with a bootloader compiled with a newer AVR
toolchain (e.g. Debian Jessie). If you still have an ages-old bootloader
without a jump-table, as a short-term measure you can revert this change
in your run.sh. As a long-term fix we recommend you get your bootloader
updated!
Now we manage a timezone and daylight-savings aware version of
localtime. We parse UNIX timezone strings. The default (active after the
first call to localtime or localtime_r) is CET/CEST, the timezone of
Europe/Vienna. The wallclock-time osd-example demonstrates how to set a
different timezone via the timezone resource.
Note: After startup no timezone is set. So in this state querying the
timezone resource will return an empty string. After first call to
localtime (if not timezone has been set via the timezone resource) a
query to timezone will return the default timezone string for CET/CEST.
The string returned by the localtime and utc timezones now also includes
the timezone name.
New fields tm_gmtoff and tm_zone were added to the tm structure. These
are available in BSD systems and when setting special compiler
definitions on Linux.
Note: the timezone offset information in the tm structure (tm_gmtoff)
as well as in the tz structure returned by gettimeofday (tz_minuteswest)
may be wrong sign, this code is largely untested.
This patch adds an example for I2C callbacks that is very similar to
the i2c-LSM9DS0 example except that it uses a PWM device that is built
into the platform.
This patch revises the I2C and GPIO initialization code to always be
run during platform boot rather than within each process that requires
it.
This patch also revises the gpio-output example to use a pin that is
set as an output by the default pinmux configuration. Previously, it
used a pin that was set as an output by the pinmux configuration that
is in effect when the OS does not change the pinmux configuration.
This patch permits interrupts to be generated by both the I2C and GPIO
controllers for simultaneously-executing applications. The controllers
share a single interrupt pin, INTC. Prior to this patch,
quarkX1000_gpio_init() routed INTA to PIRQC and IRQ 10 (due to an
incorrect assumption that INTA is connected to the GPIO controller),
and quarkX1000_i2c_init() routed INTC to PIRQC and IRQ 9. The I2C
controller initialization is a prerequisite for GPIO initialization,
so the final configuration was that INTA and INTC were both routed to
PIRQC and IRQ 10. Thus, only the GPIO ISR was being invoked, even if
the I2C controller was actually responsible for the interrupt.
This patch refactors the I2C and GPIO ISR setup and handler code so
that the shared portions are combined in
cpu/x86/drivers/legacy_pc/shared-isr.[ch]. The I2C and GPIO drivers
communicate their interrupt information to the shared component by
placing structures in a specific section of the binary.
Directories listed in this variable are added to include and
source (vpath) search paths.
Contents of this variable aren't automatically prefixed with
Contki root. This allows for inclusion of folders that are
outside Contiki root.
When SICSLOWPAN_FRAMER_HDRLEN is defined its value is used
as a frame header length. This allows for using sicslowpan
without calling a framer. This is usefull if framer is not
used on a given platform or when header length is always
the same.
In addition this commit also fixes an inline define.

Make Travis CI use the GNU ARM Embedded toolchain version specified by
the READMEs, instead of automatically using the latest version provided
by the PPA. In this way, the READMEs will still be correct after a PPA
upgrade, and the version used by Contiki is under control.
