FeaturesThe following standard features are provided.• Choice of RTOS scheduling policy1. Pre-emptive:Always runs the highest available task. Tasks of identical priorityshare CPU time (fully pre-emptive with round robin time slicing).2. Cooperative:Context switches only occur if a task blocks, or explicitly callstaskYIELD().• Co-routines (light weight tasks that utilise very little RAM).• Message queues• Semaphores [via macros]• Trace visualisation ability (requires more RAM)• Majority of source code common to all supported development tools• Wide range of ports and examples
The download includes the kernel source code, and a demo application for EVERY
RTOS port. See http://www.FREErtos.org/a00017.html for full details of the
directory structure and information on locating the files you require.
The easiest way to use FREErtos is start start with one of the demo application
projects. Once this is running the project can be modified to include your own
source files. This way the correct files and compiler options will be
automatically included in your application.
+ The Source directory contains the real time kernel source files for every
port. The kernel itself is only 3 files.
+ The Demo directory contains the demo application source files for every
port.
+ The TraceCon directory contains the trace visualisation exe file.
See the readme files in the respective directories for further information.
