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.

* Cleanup
* Fix warnings
* Fix indentation
* Only wait 1ms for keyboard timeout
* Hide text cursor
* Pump mouse events just in case
* Add F9 as menu key since F10 is used as menu trigger by Gnome
This is a general cleanup of things like code style issues and code structure of the STM32w port to make it more like the rest of Contiki is structured.
- Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs.
- Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer.
- Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered.
- Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.
Both the source code and the cc65 compiler have changed. So it made sense to review which object files are to be compiled for placement in the Language Card.
This reverts commit 029bc0ee27, reversing
changes made to a7b3e99644.
This uses LGPL libopencm3. While the patch doesn't include the code,
the resulting binary would force the release of all code as LGPL.
Relevant cc65 changes...
General:
- The compiler generates "extended" dependency info (like gcc) so there's no need for postprocessing whatsoever :-)
- The linker is very pernickety regarding the ordering of cmdline options so a custom linker rule is necessary :-(
Apple2:
- The various memory usage scenarios aren't specified anymore via separate linker configs but via defines overriding default values in the builtin linker config.
Atari:
- The builtin linker config allows to override the start addr so there no more need for a custom linker config.
- The C library comes with POSIX directory access. So there's no more need for for a custom coding.
CBM:
- The C library comes with POSIX directory access. So there's no more need for for a custom coding.
This platform is a basic waveshare stm32f107 devkit which contains a
USART, USB device port, some buttons and some LEDs. Unfortunately not
enough to bring up networking, but enough to test building and a
simple contiki shell
This is a major change to how the main tick interrupt is handled on
the mc1322x platforms. Instead of using two timer resources, TMR0 and
RTC, this patch unifies all the timers to use the RTC. This is enabled by
implementing etimers as scheduled rtimers. The main advantage (aside
from freeing TMR0 for general use) is have the Contiki timebase come
from the same source that will be used for sleeping and wakeup.
This patch enables automatic route setup and cleanup when
starting and stopping the minimal-net target on OS X.
Both IPv4 and IPv6 are supported.
Using the minimal-net target on OS X was absolute hell
before I came up with this patch. Now it is painless.
The minimal-net target, as currently written, wakes up the
CPU every millisecond to check for packets, and will only
react in real-time to input from stdin. If you are running
this on a laptop battery, your battery will quickly drain.
This change allows the CPU to idle when there is literally
nothing to do while still being responsive to input from
stein and/or incoming packets. This fix should significantly
improve performance while significantly improving power
usage. Win-win.
Also added `_xassert()` implementation so that the contiki-
provided `assert()` macro will work properly when used
on this platform.
Setting UIP_CONF_IPV6 to zero from the make build command line is
something that seems like it should ensure that IPv6 is disabled, but in
fact it actually *enables* IPv6. This seems counter intuitive, so this
patch changes the behavior of the makefiles to handle this case
properly.
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.
configuration system.
(also deprecate TARGET=redbee-econotag)
- mc13224v now automatically probes hardware config for buck converter
and 32kHz crystal as well as automatically monitors battery voltage
and manages the buck accordingly.
- new flashed based config system for mc13224v parameters such has
radio modes (demod, autoack), nvmtype, mac address, channel and
power.
- considerably cleaned up econotag platform code (suffered from severe
case of bit-rot)
Copied this file to the platform directories and
changed it to use putstring(), puthex() etc so
that we can print addresses without linking in
printf
See Pull Request #20
This is based on a usb-test example by Philippe Retornaz. It has
been moved to platform and modified accordingly. With this in place:
- putchar() can work over USB. So we can use things like
printf, slip output
- USB input can be redirected to slip or serial input
The example itself is no longer needed in the source tree
See Pull Request #18
The P2 Interrupt is shared across many periferal (I2C, USB, GPIO).
This adds a generic interrupt handler on which the differents drivers
can register a handler.
See Pull Request #18
r is now uint8_t, allocated to registers
len is uint16_t for more efficent arithmetic
(Changes replicated from the 253x port, originally
contributed by Philippe Retornaz - EPFL)
- Moved to their own file
(so we can later copy the entire thing over to cc2430)
- Renamed the functions
(for naming convention reasons)
- The entire thing can be enabled/disabled
- Added a couple more macros
- Hooked into main()
__bit variables must be located after the 0x20 address
This force the stack to start after 0x20, thus decrease
the stack size by a considerable amount.
- Relevant examples explicitly request it in their Makefile
- Removed the definition of UIP_CONF_IPV6_RPL from
contiki-conf.h. If needed, it's defined through a -D
This allows us to reduce CODE footprint of SDCC projects
built with --model-huge. Use carefully!
* Added a facility which allows us to enable/disable the
feature from the CPU dir (CC_CONF_NON_BANKED_OPTIMIZATION)
* Added the CC_NON_BANKED keyword to some platform files
(expands to __nonbanked)
* Started using this for some examples
We still use the primary location by default (Info Page) but
this is now configurable. This change is useful for users who
wish to specify their own MAC address. Since the Info Page is
read-only, they need to be able to use the secondary location
This will help us slowly add better support for smaller SoCs
instead of just assuming that all cc253x SoCs are F256
- We build for F256 by default but the project Makefile can override this
- We currently ignore this when passing --code-size. This is a ToDo
- The bank allocator always assumes 7 banks. Once we fix --code-size above this will be irrelevant
This new approach (CLOCK_CONF_ACCURATE=0) was not as inaccurate
as originally thought. In fact, it has pretty much the same
accuracy as the old, stack-hungry version.
* Renamed the define from CLOCK_CONF_ACCURATE (1: old) to
CLOCK_CONF_STACK_FRIENDLY (1: new) to stop implying
that one is more accurate than the other.
* Using CLOCK_CONF_STACK_FRIENDLY by default.
Unlike cc2430, the cc2530 RF driver never generates interrupts.
This configuration in main() was a remnant of the porting from
the sensinode main, which does in fact need it.
Also updated comments in contiki-conf to reflect that shortcuts
don't influence the RF
Since the introduction of a purpose-written routine, the old
generic one (which was written in asm) was never being used.
There was a configuration directive which allowed us to switch
between the two. All references to this configuration directive
have also been removed.
NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE for redbee-dev and econotag
Removed the obsolete MAC_CONF_CHANNEL_CHECK_RATE (now replaced with
NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE)
