MiniOS Readme!

• MiniOS Version 1.0

  • Mini multitasking RTOS for microcontrollers
  • 2005-2018, Author: Hj. Kern

• MiniOS is a

  • Multitasking RTOS

  • Micro-kernel with event-driven cooperative task switching

  • Especially - but not only - fits 8-bit microcontroller systems which have inherently limited resources

  • Easily scalable and configurable at compile time

  • Very small stack size, uses the call-return hardware stack

  • Small code size

    Example: Uses less than 2kB code-rom and less than a 100 bytes data-ram for a system with 4 tasks, mailbox and semaphores

  • ROM/FLASH-able

  • Supports up to 250 tasks as fore- or background tasks

  • Implements priority- and round-robin-based scheduling

  • Task priorities between 0 (highest) and 250 (lowest)

  • OS-timing: System timer requires only a single tick-interrupt which can also be used within the user application

  • Timer-services include system-tick, delays and waiting with timeouts

  • Supports counting semaphores

  • Supports a global event mailbox with byte-messages

  • Low interrupt latency - minimal disabled interrupts within the kernel

  • Portable - ANSI C implementation

  • No compiler- and target-specific extensions

  • No assembler code

  • Easy to use - employs standardized RTOS methods and terminology

  • Full source code available
