The highly configurable nature of eCos allows the operating system to be customised to precise application requirements, delivering the best possible run-time performance and an optimised hardware resource footprint. A thriving net community has grown up around the operating system ensuring on-going technical innovation and wide platform support.HAL/Device Drivers: YES Home Page: http://ecos.sourceware.org/ Licence: GPL+ Linking Exception Notes: port is available in cvs for stm3210E Eval Board which targets stm103 (flash+adc+serial+spi+usb+wallclock drivers implemented) Chibios/RtChibiOS/RT is designed for deeply embedded real time applications where execution efficiency and compact code are important requirements. This RTOS is characterized by its high portability, compact size and, mainly, by its architecture optimized for extremely efficient context switching. Feature highlights:

It's features include:+ Non preemptive multithreading. + Events. + Periodic and one-shot timers. + Dynamic heap memory allocation. + Interrupt driven streaming I/O. Main features of the TCP/IP stack are: + Base protocols ARP, IP, ICMP, UDP and TCP. + User protocols DHCP, DNS and HTTP. + Socket API. + Host, net and default routing. + Interrupt driven Ethernet driver.

HAL/Device Drivers: YES Home Page: http://www.bertos.org/ Licence: GPL+ Linking Exception ContikiContiki is designed for microcontrollers with small amounts of memory. A typical Contiki configuration is 2 kilobytes of RAM and 40 kilobytes of ROM. Contiki provides IP communication, both for IPv4 and IPv6. Contiki and its uIPv6 stack are IPv6 Ready Phase 1 certified and therefore has the right to use the IPv6 Ready silver logo.
Contiki is developed by a group of developers from industry and academia lead by Adam Dunkels from the Swedish Institute of Computer Science. The Contiki team currently has sixteen members from SICS, SAP AG, Cisco, Atmel, NewAE and TU Münich HAL/Device Drivers: Partial Home Page: http://www.sics.se/contiki/ Licence: BSD-style license Notes: port is in cvs for STM32F103 http://contiki.cvs.sourceforge.net/viewvc/contiki/contiki-2.x/cpu/arm/ Network stack focused on radio communication / wifi TinyOSTinyOS is an open source, BSD-licensed operating system designed for low-power wireless devices, such as those used in sensor networks, ubiquitious computing, personal area networks, smart buildings, and smart meters. A worldwide community from academia and industry use, develop, and support the operating system as well as its associated tools, averaging 35,000 downloads a year.HAL/Device Drivers: YES Home Page: http://www.tinyos.net/ Licence: BSD Notes: There is a STM32 port under way , see here http://tschmid.webfactional.com/projects/1/ and the source code can be found here https://github.com/tschmid/tinyos-2.x/tree/stm32 |
