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.
