uScheduler

usage

• approximately 5us to run the scheduler on esp8266
• use interval to set intervals between execution in milli seconds
• use semaphore > 0 to specify number of runs, semaphore = -1 for infinity
• each execution reduces semaphore by 1, and semahpore = 0 skips code execution
• semaphore can be set with setSemaphore function
• there is a functionless mode added for those who dont need/like function pointers just input NULL as the callback argument

void callback(void)
{
  // do something
  // delay is set by the constructor, no need to add delay here
}
task1 uScheduler(500, callback, 10);    // run callback() 10 times each 500ms
task2 uScheduler(200, NULL, -1);        // checkRun returns true every 200ms for unlimited times(-1)
loop()
{
  task1.checkRun();     //  check if the interval has past and semaphore !=0 run else skip
  if (task2.checkRun())
  {
    //  do something, no need to define seperate function
  }

  // since no delay function is nessesary, add this so esp has some time to do background tasks
  yield();
