Apache NuttX

Compare

  Analyzed 2 days ago

NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards. Additional standard APIs from Unix and other common RTOS’s ... [More] (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()). [Less]

paparazzi

Compare

  Analyzed about 1 year ago

Paparazzi is a free and open-source hardware and software project intended to create an exceptionally powerful and versatile autopilot system by allowing and encouraging input from the community. The project includes not only the airborne hardware and software, from voltage regulators and GPS ... [More] receivers to Kalman filtering code, but also a powerful and ever-expanding array of ground hardware and software including modems, antennas, and a highly evolved user-friendly ground control software interface. All hardware and software is open-source and freely available to anyone under the GNU licencing agreement. Several vendors are currently producing and selling Paparazzi autopilots and popular accessories, making the system easy and affordable to all. The key feature of the paparazzi autopilot is its unique combination of infrared thermopiles and inertial measurement for attitude sensing, providing a robust and accurate attitude estimate that requires no ground calibration and can recover from any launch attitude. The sourcecode is hosted at GitHub http://github.org/paparazzi/paparazzi for more information see http://paparazzi.enac.fr/wiki/Git [Less]
