core/lib/settings: Generalized settings manager to work on any platform
2013-05-18 12:03:09 -07:00
Robert Quattlebaum b8c0f2de6c cpu/native: Add file-backed simulated EEPROM to native cpu.
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.

George Oikonomou 007e113ea9 Improve handling of CDC ACM line state
- For the CC2538, simplify handling of USB_CDC_ACM_LINE_STATE
  events. Ignore the Carrier Control (RTS) bit when receiving
  a SET_CONTROL_LINE _STATE request, we are a full duplex device.
- Improve behaviour of the CC2531 USB stick when there is no
  process on the host to read IN data. Basically, we adopt the
  CC2538 approach and we only send data when a DTE is present

Robert Quattlebaum 28a1e40ebd core/lib/settings: Generalized Settings Manager to work on any platform
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.

Mariano Alvira ab8fe95864 Revert "Merge pull request #120 from Jeff-Ciesielski/stm32_cl"
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.

Robert Quattlebaum 67a39618eb cpu/avr: Make sure that GCC removes all unused symbols.
This magic comes from the `--gc-sections` linker flag, which turns on garbage collection for unused input sections. The compiler flags `-ffunction-sections` and `-fdata-sections` make sure that each function and each static data definition have their own section. The result is that GCC can prune away all unused symbols, reducing the size of the resulting executable.

These optimizations may be disabled by setting the Makefile variable
`SMALL` to zero.

Oliver Schmidt 98060c1eab Moved from last cc65 release (2.13.3) to recent cc65 snapshot (2.13.9).
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.

Mariano Alvira fb8bbf37cf Use the RTC only as the main timer.
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.

Robert Quattlebaum a571b663b0 platform/minimal-net: Better, more seamless support for OS X.
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.

Robert Quattlebaum 092b6f3baa platform/minimal-net: Implement better idle behavior.
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.
