+============================ +RIOT is a real-time multi-threading operating system that supports a range of +devices that are typically found in the Internet of Things: from 16-bit +microcontrollers to light-weight 32-bit processors. + +RIOT is based on the following design principles: energy-efficiency, real-time +capabilities, small memory footprint, modularity, and uniform API access, +independent of the underlying hardware (this API offers partial POSIX +compliance). + +New features +============ +Core +---- ++ msg_receive() with timeout ++ LPM support for MSP430 based platforms ++ introduced a version string + +Supported platforms +------------------- +Additional support for the following boards: ++ TelosB ++ mbed LPC1768 + +Sensor drivers +--------------- ++ drivers for the LM75A Digital temperature sensor and thermal watchdog ++ SRF02 and SRF08 ultrasonic range finders + +Native port +----------- ++ implemented UART via I/O redirection or TCP and UNIX socket + +System libraries +---------------- ++ Mersenne twister pseudorandom number generator ++ crypto libraries + + 3des + + aes + + rc5 + + skipjack + + twofish ++ BSD-like package system for easy integration of external libraries + +Network stack +------------- ++ port of CCN lite ++ POSIX socket wrapper ++ integration of libcoap ++ integration of OpenWSN + +Further Changes +=============== +* boards and projects repositories have been integrated and are now part of + the RIOT repository itself +* full refactoring of the network stack and introducing a substructure + according to the modules' functionalities +* cleaned up Makefile system and simplified binary folder +* more documentation +* various bug fixes and cleanups + +Fixed Issues from the last release +================================== +#83: Wrong byte order in sixlowpan + To our best knowledge all occurrences of wrong byte order within the 6LoWPAN + network stack are fixed now. +#132: segfault in vtimer update shortterm + The vtimer has been carefully evaluated and all known issues concerning this + module are fixed. + +Known Issues +============ +#21: Deal with stdin in bordermultiplex.c + Not all supported platforms provide a stdin in the current release. + However, the implementation of the 6LoWPAN border router won't work + without stdin. +#45: bit field order in the fcf may be wrong + The CC2420 FIFO expects the IEEE802.15.4 FCF field in reversed bit order. + This might break the implementation for other, upcoming radio + transceivers. +#82: Setting STATUS_REPLY_BLOCKED thread to STATUS_PENDING though it is not + handled yet + In some rare cases the status of a thread might falsely change to + STATUS_PENDING instead of STATUS_REPLY_BLOCKED. +#426: Interrupt handling on MSP430 is buggy + UART and timer handling is currently unstable on MSP430 based platforms +#455: sha256 is broken on MSP430 + For unknown reasons sha256 calculates wrong results on MSP430 based platforms. +#495: native not float safe + When the FPU is used when an asynchronous context switch occurs, either the + stack gets corrupted or a floating point exception occurs. +#498: native is segfaulting at startup + In some cases (about 5-10%) a RIOT native process crashes with a SEGFAULT + at startup. +#499: native is segfaulting on heavy network usage + Sending more than 100 packets per second causes a SEGFAULT in RIOT native. +#505: native on FreeBSD is broken + Due to different parameter handling in FreeBSD, native is currently not + working there. + +For all issues and open pull requests please check the RIOT issue tracker: +https://github.com/RIOT-OS/RIOT/issues + +Release 2013.08 +=============== +Kernel +------ +- Microkernel with a powerful messaging system +- Multi-Threading with low overhead +- an energy-efficient, real-time capable scheduler +- small memory footprint + +Userspace +--------- +- 6LoWPAN according to RFC 4944, RFC 6282, and RFC 6775 +- TCP and UDP +- RPL according to RFC 6550 and RFC 6719 +- High resolution and long-term timers +- POSIX IO and BSD socket API +- Bloom filter +- SHA256 + +Hardware Support +---------------- +- various ARM and MSP430 MCUs + * ARM7 NXP LPC2387 + * TI MSP430F1612 + * TI CC430F6137 + * ARM7 Freescale MC13224v (preliminary) + * ARM Cortex-M4 STM32f407vgt6 (preliminary) + * ARM Cortex-M3 STM32f103rey6 (preliminary) +- radio drivers
