Now the necessary settings are in adc.h. Refactored to allow repeated
ADC reads without reinitialization. Arduino allows setting
analogReference, this is now also implemented.
ADC is now initialized to sane values in apps/arduino/arduino-process.c
dev/arduino/arduino-compat.h now has all hardware independent settings
for arduino (some moved from platform/osd-merkur/dev/hw-arduino.h).
turnOffPWM re-implemented with hw_timer, removed from wiring_digital.c
ADC-specific arduino stuff moved to arduino-compat.h
Arduinos wiring_analog no longer necessary.
arduino-sketch example now reads analog inputs 1 and 5 using analogRead.
Now there is a generic resource that can generate and parse
application/json as well as text/plain. It can be re-used, only the
from_string and to_string routines have to be written and the resource
properly set up. A new resource format is specified, see
GENERIC_RESOURCE in, e.g., examples/osd/pwm-example. This is now used in
all my examples, namely pwm-example, arduino-sketch, wallclock-time.
There was an off by one error for the month in time formatting (in
gmtime and localtime). And the leap-year computation was broken. Both
fixed now, so we get a correct date. For localtime we are still 2 hours
off because daylight saving isn't implemented yet.
Also renamed gmtime to utc.
New discovery: Contiki also uses timer 0. With almost the same interface
as Arduino. So we now completely get rid of wiring.c (only the main
file, the other wiring_xxx stay) and implement Arduino timer, delay, etc
in terms of the corresponding Contiki routines. Verified that now delay
works as expected. The LED in examples/osd/arduino-sketch blinks!
Before this, the arduino_init routine in wiring.c destroyed the timer-0
initialization of contiki, making both, contiki timer implementation
*and* contiki timer implementation fail if the arduino_init routine was
called. Now both work.
Squashed with following bug-fix commit.
We can now directly compile arduino sketches (.pde) files.
Arduino compatible analogWrite works now.
But there is still a long way to go, serial I/O and timer stuff (delay,
millis etc) currently don't work (not tested but I don't expect this to
work).
It can be used in an arduino sketch or in a normal contiki program.
We get a PWM frequency of 490.2 Hz (a period of 2.040 ms), that's
Arduino compatible. If you need different frequencies see native timer
usage in examples/osd/pwm-example
In a contiki program you have to call arduino_pwm_timer_init to
initialize the timer before pwm works. The arduino sketch wrapper
already does this.
For running a sketch, see examples/osd/arduino-sketch
New application and new example.
We use the built-in timer routines and add an offset to get the
wallclock time. The offset can be set by time-changing routines
(currently only settimeofday).
We also maintain an offset for timezone handling but this isn't
currently fully implemented.
Current default in the Makefile is the *new* bootloader address.
But for backward compatibility we've modified the run*.sh files
to use the old address. The run*.sh also now explain how to change
the default.
- Remove unused variable i in generate_routes.
- Add cast to unsigned long for printf(..%lu..) in generate_routes.

Some calls to `rpl_set_root` select a hardcoded DODAG ID

This is a very simple modification that affects a very large number of files in Contiki: Cooja,
/platform/cooja, Collect-view, Coffe-manager, and Cooja simulation files (.csc).
I've gone through Contiki to update all references I could find. Nevertheless, this commit will likely
break external dependencies, like saved Cooja simulation files.

Don't be afraid, I'm not trying to have more retro platforms than "real" platforms ;-)
The platform 'atarixl' will replace the platform 'atari'. However I need both for some
transition period.
This example didn't compile, had no actual code changes in the last ~6
years, had no documentation explaining it's purpose, and insufficient
code comments to provide a useful example. Removing it in favour of
fewer, but clearer, examples, that are easier to keep maintained.
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.
---------------------------------
examples/udp-ipv6: Updated client to use MDNS to lookup the server.
Also updated the Cooja regression test simulation.
On the C128 the custom PFS code doesn't add functionality (as it does with IDE64 support on the C64) but is "only" smaller than the POSIX file i/o code in the C library. But the stdio code in the C library (used in WGET for screen i/o) relies on the POSIX file i/o code anyway so there no point in additionally adding the PFS code to the WGET program.

declarations of functions for setting and getting a node ID number, a
functionality that exists on many platforms. Since this functionality
was not considered part of the Contiki core, each platform defined its
own node-id.h file. This commit attempts to clean this up by
collecting the node-id.h into a core/sys/node-id.h file that replaces
the old node-id.h files from the platform directories.
