This PR simply adds a packet sent callback to the unicast connection used in the example. Every time a packet is sent the callback is called and prints the linkaddr_t dest, the MAC status of the message sent, and the link layer number of transmissions of the packet. This can be used to compute link quality estimations.
This test could sometimes fail because of a lack of free contiguous
pages in the file system. Fix this by removing the created files at the
end of each test. Besides, the test files do not have to be removed at
the beginning of each test since the file system is initially formatted.

The r variable was used instead of i to fill the buffer, resulting in
the end of the test loop after only a single iteration. The file was not
even closed at the end of each iteration although it is opened at the
beginning of each iteration, so the available file descriptors would
very quickly be exhausted.

Two errors have been spotted, when IPv6 is enabled in the ravenusb
Project-Makefile:
#CONTIKI_NO_NET=1
CONTIKI_WITH_IPV6=1
The compile error results from a variable name mismatch in cdc_task.c
The variable 'r' is undeclared and should be renamed to 'route'
The linker also fails with 'undefined references'
This has been mediated by adding 'core/net' to Modules in the
Project-Makefile.
This patch adds a simple non-driver protection domain sample to serve
as an example for defining other non-driver protection domains. It
simply performs a ping-pong test of protection domain switching
latency during boot, including optional accesses to a private metadata
region, and prints out the results.
Now that the CBM PFS supports file removal (and a file seek stub) it is possible to have the Telnet server leverage the IDE64 support of the CBM PFS.
Note: Using the CBM PFS for the Telnet server does _not_ reduce the code size since the POSIX I/O functions are additionally still linked in because the POSIX directory functions internally use the POSIX I/O functions. And that's the very reason why the CBM PFS is _not_ activated for the C128 Telnet server: The CBM PFS for the C128 doesn't bring IDE64 support but is supposed to be used to reduce code size - but this isn't possible for the Telnet server.
This patch implements a simple, lightweight form of protection domains
using a pluggable framework. Currently, the following plugin is
available:
- Flat memory model with paging.
The overall goal of a protection domain implementation within this
framework is to define a set of resources that should be accessible to
each protection domain and to prevent that protection domain from
accessing other resources. The details of each implementation of
protection domains may differ substantially, but they should all be
guided by the principle of least privilege. However, that idealized
principle is balanced against the practical objectives of limiting the
number of relatively time-consuming context switches and minimizing
changes to existing code.
For additional information, please refer to cpu/x86/mm/README.md.
This patch also causes the C compiler to be used as the default linker
and assembler.
This patch adds an example program to print out information about the
configuration of the Intel Quark X1000 SoC Isolated Memory Regions
(IMRs), the Host System Management Mode Controls register, and the
Host Memory I/O Boundary register.
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.
Also added a 2-minutes average wind direction value, replaced the 240 bytes buffer from the reference example, but probably there's room for efficiency improvement
The PKA drivers and examples were full of include paths missing the
appropriate prefix, or using angle brackets instead of double quotes or

This patch introduces an example application to demonstrate how to use
GPIO driver APIs to manipulate interrupt pins.
The application uses default galileo pinmux initialization and sets
the GPIO 5 (IO2) as output pin and GPIO 6 (IO3) as interrupt. It toggles
the output pin stat at every half second in order to emulate an interrupt.
This triggers an interrupt and the application callback is called.

This commit adds a very simple example which is useful to verify

the first process tests etimer, timer and stimer APIs, the second
process tests the ctimer APIs, and the third one tests the rtimer
APIs.
The peripheral core clocks of the PWM timers are gated in PM1+, so these
power modes must be disabled if a PWM timer is running. Use
lpm_register_peripheral() to handle this automatically and dynamically.

So far 80 column display was an attribute of a cc65 platform. Now each cc65 application can ask for 80 column display by defining WITH_80COL. Of course this is ignored by platforms incapable of 80 column display.
I see three types of application:
* Applications not benefitting from 80 column at all and in fact looking better with 40 column display. These are now using 40 column display. Examples: ethconfig, ipconfig
* Applications taking advantage of 80 column display if it is available without drawbacks. These stay as they were. Examples: Telnet server, web server, wget
* Applications needing 80 column display so urgently that it is likely desirable even if the display becomes harder to read. These come now in both flavors allowing the user to choose. Examples: IRC, web browser
Note: This change doesn't actually introduce any 80 column display with drawbacks. This if left to a subsequent change.
The current version of the CC26xx web demo publishes over MQTT the default parent's IPv6 address and the last observed RSSI of this link. This is collected by active probing (periodic ping).
This commit brings the probing functionality to the example's main code module. The MQTT client keeps publishing as previously, but we now also export the same information through CoAP resources. Configuration is still possible through the example's web server.
This demonstraties how to combine CC13xx tick suppression, RPL leaf mode and turning off ContikiMAC duty cycling to build an extremely low-consuming firmware.
In order to have the wget command make some sense the write command should be present too.
- On the Apple][ reduction of the MTU seems to gain just enough RAM to have the (rather heavy-weight) full-blown C library file I/O working.
- On the C128 there's way too little RAM so there's no wget command but only the file commands.
- On the CBMs a dummy lseek() was necessary to have the read command link.
Several keys can be kept at the same time in the key store, and several

Using the AES interrupt allows the user process not to waste time
polling for the completion of the operation. This time can be used by
the user process to do something else, or to let the system enter PM0.
Since the system is now free to perform various operations during a
crypto operation, a protection of the crypto resource is added, and PM1+

This patch removes a defunct EEPROM implementation from the native
platform and provides a new EEPROM implementation for the native cpu.
The previous implementation appears to be vestigal.
This is useful for testing code which uses the EEPROM without running
the code on the actual hardware.
By default the code will create a new temporary file as the EEPROM
backing, reinitializing each time. If you would like to preserve the
EEPROM contents or specify a specific EEPROM file to use, you can set the
`CONTIKI_EEPROM` environment variable to the name of the EEPROM file you
wish to use instead. If it already exists, its contents will be used.
If it does not already exist, it will be created and initialized by
filling it with `0xFF`---just like a real EEPROM.
A new example is also included, which was used to verify the correctness
of the implementation. It can easily be used to verify the EEPROM
implementations of other targets.
This commit moves the Settings Manager from the AVR codebase
into the Contiki core library. Any platform that implements
the Contiki EEPROM API can now use the Settings Manager's
key-value store for storing their persistent configuration info.
The Settings Manager is a EEPROM-based key-value store. Keys
are 16-bit integers and values may be up to 16,383 bytes long.
It is intended to be used to store configuration-related information,
like network settings, radio channels, etc.
* Robust data format which requires no initialization.
* Supports multiple values with the same key.
* Data can be appended without erasing EEPROM.
* Max size of settings data can be easily increased in the future,
as long as it doesn't overlap with application data.
The format was inspired by the [OLPC manufacturing data format][].
Since the beginning of EEPROM often contains application-specific
information, the best place to store settings is at the end of EEPROM
(the "top"). Because we are starting at the end of EEPROM, it makes
sense to grow the list of key-value pairs downward, toward the start of
EEPROM.
Each key-value pair is stored in memory in the following format:
Order | Size | Name | Description
--------:|---------:|--------------|-------------------------------
0 | 2 | `key` | 16-bit key
-2 | 1 | `size_check` | One's-complement of next byte
-3 | 1 or 2 | `size` | The size of `value`, in bytes
-4 or -5 | variable | `value` | Value associated with `key`
The end of the key-value pairs is denoted by the first invalid entry.
An invalid entry has any of the following attributes:
* The `size_check` byte doesn't match the one's compliment of the
`size` byte (or `size_low` byte).
* The key has a value of 0x0000.

This patch updates the DNS resolver to support IPv6 and introduces an
improved API for looking up DNS entries. This patch also adds optional
support for mDNS lookups and responses to the DNS resolver.
Here is a quick summary of the changes:
* Added support for IPv6 lookups.
* DNS queries now honor record expiration.
* Added support for mDNS, compatible with "Bonjour".
* Implemented a new lookup api, `resolv_lookup2()`, which provides
more information about the state of the record(error, expired,
looking-up, etc.).
About mDNS/Bonjour Support
--------------------------
This patch adds basic support for mDNS/Bonjour, which allows you to
refer to the name of a device instead of its IP address. This is
incredibly convenient for IPv6 addresses because they tend to be very
long and difficult to remember. It is especially important for
link-local IPv6 addresses, since not all programs support the '%'
notation for indicating a network interface (required on systems with
more than one network interface to disambiguate).
In other words, instead of typing in this:
* `http://[fe80::58dc:d7ed:a644:628f%en1]/`
You can type this instead:
* `http://contiki.local/`
Huge improvement, no?
The convenience extends beyond that: this mechanism can be used for
nodes to talk to each other based on their human-readable names instead
of their IPv6 addresses. So instead of a switch on
`aaaa::58dc:d7ed:a644:628f` triggering an actuator on
`aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the
actuator on `living-room-lights.local`.
What you need to do to be able to look up `.local` names on your
workstation depends on a few factors:
* Your machine needs to be able to send and receive multicast packets
to and from the LoWPAN. You can do this easily with the Jackdaw
firmware on an RZUSBStick. If you have a border router, you will need
it to bridge the mDNS multicast packets across the border.
* If you are using a Mac, you win. All Apple devices support mDNS
lookups.
* If you are using Windows, you can install Apple's Bonjour for Windows
package. (This may be already installed on your machine if you have
installed iTunes) After you install this you can easily do `.local`
lookups.
* If you are using a Unix machine, you can install Avahi.
The default hostname is set to `contiki.local.`. You can change the
hostname programmatically by calling `resolv_set_hostname()`. You can
change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`.
You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to
`0`.
---------------------------------
core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()`
Note that this patch should fix several `resolv_lookup()` bugs
that already existed. There were many cases where `resolv_lookup()`
was being called and the IP address ignored, but later code
assumed that the IP address had been fetched... ANYWAY, those
should be fixed now.
