Micro-Controller Operating Systems (MicroC/OS) is a real-time operating system (RTOS) designed by embedded software developer, Jean J. Labrosse in 1991. It is a priority-based pre-emptive real-time for microprocessors, written mainly in the C programming language. It is intended for use in embedded systems. MicroC/OS allows you to define several functions in C, each of which can execute as an independent thread or task. Each task runs at a different priority, and thinks that it owns the CPU. Lower priority tasks can be preempted by higher priority tasks at any time. Higher priority tasks use operating system services (such as a delay or event) to allow lower priority tasks to execute. There are operating system services provided for task management, inter-task communication, memory management, and for timing. ==History== The MicroC/OS kernel was originally published in a three-part article in Embedded Systems Programming magazine and the book "µC/OS The Real-Time Kernel" by Jean J. Labrosse (ISBN 0-87930-444-8). The author intended at first to simply describe the internals of a portable operating system he had developed for his own use, but later developed the OS as a commercial product in versions II and III.
