Simple preemptive, realtime, multitask kernel made just for fun.

uLipeRTOS Version 4 is a simple, but powerful real time kernel, currently implemented for arm cortex M3 and M4 processors. The kernel uses a fully preemptive schedule policy, and supports up to 1024 priority levels.

Main features:

• Real time, preemptive kernel;
• Fast context switching time, below to 100ns @ 50MHz processor clock;
• Fully configurable thru a config header file;
• Supports up to 1024 priority levels;
• Event flag groups, up to 32bits events;
• Counting semaphores;
• Binary semaphores;
• Queueing by reference support;
• Port file formed by two simple files in C and Assembly, simple to port;
• Unlimited kernel objects (limited by processor memory);
• Run time creation objects;
• Except port file, implementend in fully ANSI-C.
