Macros:

#define _COOP_NMB_OF_TASK

How to use this library

The CoOp Core library can be used as follows:

1. Add coop_core.h header

2. Set the max number of tasks in coop_core_conf.h header, for example:

/* -------- Configuration -------- */
#define _COOP_NMB_OF_TASK 3

3. Add Task_IncTick() in the 1ms timer ISR:

Timer_ISR()
{
	Task_IncTick();
}

4. Create the Tasks and her functions:

cTask_TypeDef Task1;
cTask_TypeDef Task2;
cTask_TypeDef Task3;

void Task1Func(uint8_t *argument)
{
  LED1_Toggle();
  Task_Delay(500, 0);
}

void Task2Func(uint8_t *argument)
{
  LED2_Toggle();
  Task_Delay(500, 0);
}

void Task3Func(uint8_t *argument)
{
  switch(*argument)
  {
    case 0: // Step 0 is default
    {
      LED3_On();
      Task_Delay(250, 1); // Wait 250ms and goto step 1 (case 1)
    }
    break;
    case 1: // Step 1
    {
      LED3_Off();
      Task_Delay(250, 0); // Wait 250ms and goto step 0 (case 0)
    }
    break;
    
    default:
    break;
  }

}

5. Register Tasks and run CoOp System, for example:

/* Register User Tasks */
Task_RegisterNew(&Task1, Task1Func);
Task_RegisterNew(&Task2, Task2Func);
Task_RegisterNew(&Task3, Task3Func);
	
/* Run CoOp System */
Task_RunCoOpSystem();
