RRrun
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Realtime Roundrobin
Introduced first in SolidGeometry 3.5, Creation date: 2017-03-02, Last change: 2025-09-14
starts Round-Robin Task-List Realtime Environment in stopped state
Description
Matlab is used to execute the task strings as command line and task handles as function call.
The user has the feeling to use the Matlab command interface but in fact in parallel a set of functions runs as round robin task list.
Some commands are helpful to understand the environemnt:
whos - shows all variable used in this environment
RRprompt - Prompt string 'RRrun'
RRtasklist.t0 = cycle time
Some command line commands are new or treated in a different way:
QUIT, EXIT - stops the shell; it can be restarted by RRrun, persistent/global
LIST, SHOW shows the task list
ADD - appends a task at the end of the task list
STEP - executes the task list exactly one time
CONT, GO, START - starts the task execution
STOP, BREAK - stops the task execution
SAVE - saves the task in a file in the current directory
LOAD - load the task list from a file in the current directory
KILLALL - deletes all tasks in the task list
KILL # - delete the task with the 3rd column has the unique nr #
EXE, EXECUTE - reads in command text file and executes all commands, requires START
Have in mind that inter task communication is only possible by variables declared as global!
