= Scheduler library for Arduino =

This library allows an Arduino board to run tasks at specific frequency.

For more information about this library please visit us at https://github.com/Robokishan/Taskrunner

Project is inspired from scheduler of betaflight

Declare

Scheduler scheduler;

Declare a task

Declare the function and add that call back function to the task

void taskBlink(timeUs_t currentTimeUs){
    scheduler.Logln("Blink %d second",1);
    digitalWrite(LED_BUILTIN,!digitalRead(LED_BUILTIN));
}

task_t tasks[TASK_COUNT] = {
    [TASK_BLINK] = DEFINE_TASK("BLINK", NULL, taskBlink, TASK_PERIOD_HZ(10), TASK_PRIORITY_MEDIUM_HIGH),
}

Declare task Another way

Scheduler scheduler;

// Function structure should be same void as return  type and argument as timeUs_t
void taskBlink(timeUs_t currentTimeUs);

task_t tasks[TASK_COUNT] = {
    [TASK_BLINK] = DEFINE_TASK("BLINK", NULL, taskBlink, TASK_PERIOD_HZ(1), TASK_PRIORITY_HIGH),
};

void setup() {
    Serial.begin(115200);
    pinMode(LED_BUILTIN,OUTPUT);
    scheduler.queueClear();
    scheduler.debug(true);//default is false
    scheduler.setTaskEnabled(TASK_BLINK, true);
}

void loop() {
      scheduler.run_scheduler();
}

void taskBlink(timeUs_t currentTimeUs){
    scheduler.Logln("Blink %d second",1);
    digitalWrite(LED_BUILTIN,!digitalRead(LED_BUILTIN));
}

Enable Task

scheduler.setTaskEnabled(TASK_BLINK, true);

Disable Task

scheduler.setTaskEnabled(TASK_BLINK, false);

Run Scheduler

void loop() {
    scheduler.run_scheduler();
}

Don't Forget

Inside Scheduler.h

inside scheduler.h you need to add your custom task ids

typedef enum {
    /* Actual tasks */
    TASK_SYSTEM = 0,
    TASK_BLINK, //your custom taskid 
    <ADD YOUR TASK>,
    /* Service task IDs */
    TASK_NONE = TASK_COUNT,
    TASK_SELF
} taskId_e;
