PR_RTX
is a task switcher for the Atmel AVR processor that is easily implemented
by inserting a header file and a task control block into the code produced
by the CodeVisionAVR wizard or written by a programmer. The header file
contains all of the control structure and initializations to get the RTX
running.
A rich
variety of RTX services are provided to control task switching, timing
and task control. Tasks may be put into a wait state based on time or receipt
of a semaphore from another task or both. Tasks may be started or stopped
either from within the task itself or from another task. Tasks may switch
in a round-robin mode or in a priority mode where one task requires critical
timing control.
This
is a source code product and is packaged with both CodeVisionAVR and Imagecraft
project files.
Features

task switching control in either round-robin or priority mode

of internal and/or external SRAM based on project configuration
Includes
ability to pass inter-task semaphores with limited messaging
Tasks
may switch on other periodic signals such as the ADC or even from an external
interrupt
Complete

Revision
History
7/23/2002 Version 1.00
- Initial Release
1/7/2003 Version 2.00
- Added a method to restart a task from its initial state.
- Reconfigured PR_RTX_Control.h as PR_RTX_Control.c to better match the
definition of program vs. header.
- Added a new #define for so RTX supports ICCAVR.
11/2/2003 Version 3.00beta
- Changed data stack in PR_Create to an int to allow for bigger data stacks.
- Moved the temporary data stack to prevent problems with variables in
both compilers.
- Revised CVAVR memory map to correspond with ICC version.
- Revised to automatically detect RAM size and allocate stacks.
- Added code to allocate all existing RAM to stacks.
- Added the PR_RT_eXaminer tool.
3/25/2004 Version 3.10
- Changed eXaminer output to non-inturrupt based so eXaminer output is
valid.
- Added #define so user could choose the eXaminer's output.
