Micro-Controller Operating Systems (MicroC/OS, stylized as μC/OS, or Micrium OS) is a real-time operating system (RTOS) designed by Jean J. Labrosse in 1991. It is a priority-based preemptive real-time kernel for microprocessors , written mostly in the programming language C .
With the purchase of NeXT in late 1996, Apple developed a new operating system strategy based largely on the existing OPENSTEP for Mach platform. The new Rhapsody OS strategy was relatively simple; it retained most of OpenStep's existing object libraries under the name "Yellow Box", ported the existing GUI in OPENSTEP for Mach and made it look more Mac-like, ported several major APIs from the ...
The ArduPilot project earliest roots date back to late 2007 [10] when Jordi Munoz, who later co-founded 3DRobotics with Chris Anderson, wrote an Arduino program (which he called "ArduCopter") to stabilize an RC Helicopter. In 2009 Munoz and Anderson released Ardupilot 1.0 [11] (flight controller software) along with a hardware board it could ...
In 1997, Apple purchased NeXT in order to use their operating system, OpenStep, as the basis for future Mac products. OpenStep was based around the concept of the entire operating system and all of its applications being built using an internal development system. This was, in turn, based on the GNU Compiler Collection (GCC). While CodeWarrior ...
With the release of Mac OS X Snow Leopard, and before that, since the move to 64-bit architectures in general, some software publishers such as Mozilla [1] have used the term "universal" to refer to a fat binary that includes builds for both i386 (32-bit Intel) and x86_64 systems. The same mechanism that is used to select between the PowerPC or ...
GCD was first released with Mac OS X 10.6, and is also available with iOS 4 and above. The name "Grand Central Dispatch" is a reference to Grand Central Terminal. [citation needed] The source code for the library that provides the implementation of GCD's services, libdispatch, was released by Apple under the Apache License on September 10, 2009 ...
The emulator shipped with the ability to run Mac OS X 10.3, OpenBSD for PowerPC, NetBSD for PowerPC, Darwin for PowerPC and Mandrake Linux 9.1, though it was noted that the emulated operating systems could be up to 40 times slower than the host. [1] This speed was later brought up, running around 10 times slower than the host. [11]
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
