Features Overview
[About FreeRTOS]

FreeRTOS Features:

FreeRTOS is a scale-able real time kernel designed specifically for small embedded systems. Highlights include:

• Free RTOS kernel - preemptive, cooperative and hybrid configuration options.
• The SafeRTOS derivative product provides a high level of confidence in the code integrity.
• Official support for 30 architectures (counting ARM7 and ARM Cortex M3 as one architecture each).
• FreeRTOS-MPU supports the Cortex M3 Memory Protection Unit (MPU).
• Designed to be small, simple and easy to use. Typically a kernel binary image will be in the region of 4K to 9K bytes.
• Very portable code structure predominantly written in C.
• Supports both tasks and co-routines.
• Queues, binary semaphores, counting semaphores, recursive semaphores and mutexes for communication and synchronisation between tasks, or between tasks and interrupts.
• Mutexes with priority inheritance.
• Supports efficient software timers.
• Powerful execution trace functionality.
• Stack overflow detection options.
• Pre-configured demo applications for selected single board computers allowing 'out of the box' operation and fast learning curve.
• Free forum support, or optional commercial support and licensing.
• No software restriction on the number of tasks that can be created.
• No software restriction on the number of priorities that can be used.
• No restrictions imposed on priority assignment - more than one task can be assigned the same priority.
• Free development tools for many supported architectures.
• Free embedded software source code.
• Royalty free.
• Cross development from a standard Windows host.
