Minimal example of Task Scheduler Blink?

Question

Scheduler_example00_Blink is ~300 lines. For just an Arduino Uno, what is a minimal example?

It's hard to know what belongs and what doesn't. This example has six different approaches, and I'm just trying to extract one of them.

• jsotola: what about the scheduler template?
• jsotola: the main GitHub page for the library has a link to an awesome web based Arduino emulator .... wokwi.com/playground/task-scheduler ... try deleting sections of code until you are left with minimum
• jsotola: i don't see it as being personal ... i am glad that you were able to work through it ... learning experience ... please don't forget to accept your own answer

Answer 1

#include <TaskScheduler.h>
// Scheduler
Scheduler ts;
/*
 Approach 1: LED is driven by the boolean variable; false = OFF, true = ON
*/
#define PERIOD1 500
#define DURATION 10000
void blink1CB(); // <-------------------------------------------|
Task tBlink1 ( PERIOD1 * TASK_MILLISECOND, DURATION / PERIOD1, &blink1CB, &ts , true );
// ( 500 * 1UL (ms) , 100000 ms/ 500 , function , just put it, ? )
void setup()
{
 pinMode(LED_BUILTIN, OUTPUT);
}
void loop()
{
 ts.execute();
}
inline void LEDOn() {
 digitalWrite( LED_BUILTIN, HIGH );
}
inline void LEDOff() {
 digitalWrite( LED_BUILTIN, LOW );
}
// === 1 =======================================
bool LED_state = false;
void blink1CB()
{
 if ( LED_state )
 {
 LEDOff();
 LED_state = false;
 }
 else
 {
 LEDOn();
 LED_state = true;
 }
}
