Simple Task Scheduler

This is basically a set of timers and a very simple round-robin, run-to-completion scheduler. The scheduler runs off the millis() counter so all delays are in milliseconds.

Currently supported:

• 256 tasks
• 65535 ms max delay

Usage

Each task has 4 states:

• TASK_OFF - completely disabled and will not run, regardless of its timer
• TASK_STOP - task has run to competion and has not been put to sleep
• TASK_PEND - pending on its timer (sleeping, waiting for timeout)
• TASK_RUN - task is running (or ready to run)

In your program you need to set up a task block array, where each entry is the starting parameters for a task. Here is an example of what should be at the top of your sketch. The enumeration and NUM_TASKS are optional, if you just want to use the actual numbers.

  
// Task list where each line matches a line in the task block

enum

{

   LED_BLINK_TASK = 0,

   HELLO_WORLD_TASK

};



// The task block with starting values

TaskBlock taskBlock[] = 

{

   // Entry Point    State     Starting Count

   {&ledBlinkTask,   TASK_RUN, 0},  // LED_BLINK_TASK

   {&helloWorldTask, TASK_RUN, 0}   // HELLO_WORLD_TASK

};



// The number of tasks (automatically calculated

#define NUM_TASKS (sizeof(taskBlock)/sizeof(TaskBlock))

Then in your setup():

  
setup()

{

   // put other setup stuff here

   void TS.initialize(taskBlock, NUM_TASKS);

}



loop()

{

   TS.run();

}
