Smiley Hi I'm starting to work with OSA RTOS and am trying to make it work using the compiler MikroC PRO 4.60 and pic12f675 microcontroller, I have not made ​​it to work and need help from someone who has made ​​or more experience in this of the RTOS to please help.

Dear PCROBOTICS

I'm also a newbie in RTOS applications. It is not easy to find right documents and right libraries, even finding a "hello world" project. All the example program neither can be complied nor can be changed by the user in a simple way. But anyway I hope we will do it one day!

The main problems are adding a lot of header & source code and making a couple of configuration. Till now the simplest RTOS I have ever seen is CCS compiler's RTOS. Easy to use and no need to make a huge amount of configuration.

best regards, sughoi

Code:
include osa.h;



void Task1 (void)
{

 for (;;)
 {
    TRISB=0;
     PORTB=255;            //create task
     Delay_ms(150);
     PORTB=0;
     Delay_ms(150);
     OS_Yield();
     }



}



void Task2 (void)
{

 for (;;)
 {
    TRISB=0;
     PORTB=255;            //create task
     Delay_ms(150);
     PORTB=0;
     Delay_ms(150);
     OS_Yield();
     }



}

#pragma funcall main Task1  //this is important to MikroC
#pragma funcall main Task2


void main()

{


 OS_Init();



 OS_Task_Create(7, Task1); // 7 is priority , name of task is pointer to function where is your task in memory.
 OS_Task_Create(7, Task2);
 
 OS_Run();




}

cheers

Dear friends I have a question I want to manage three different tasks via OSA and mikroc source code, even though I configured the system for 3 different tasks the system only manages 2 different tasks. If some helps me, I will be appreciate. My two source codes (main and OSAcfg) is below;
Code:
#include "osa.h"

#define T2CON_CONST     0x25        // post = 8, period = 250*4*5* 0.2 us = 1 ms

#define PR2_CONST       (250-1)

void Init (void)

{

    TRISB = 0x00;

    PORTB = 0x00;

    T2CON = T2CON_CONST;

    PR2 = 250-1;

    INTCON = 0;

    PEIE_bit = 1;

    TMR2IE_bit = 1;

}

void interrupt (void)

{

    if (TMR2IF_bit)

    {

        OS_Timer();

        TMR2IF_bit = 0;

    }


}


void Task_1 (void)

{

    for(;;)

    {

        OS_Delay(65);

        PORTB.F0 = ~ PORTB.F0;

    }

}

void Task_2 (void)

{

    for(;;)

    {

        OS_Delay(230);

        PORTB.F1 = ~ PORTB.F1;

    }

}


void Task_3 (void)

{

    for(;;)

    {

        OS_Delay(250);

        PORTB.F2 = ~ PORTB.F2;

    }

}



#pragma funcall main Task_1

#pragma funcall main Task_2

#pragma funcall main Task_3


void main (void)

{

    Init();                             // Init periphery

    OS_Init();                          // Init OS


    OS_Task_Create(0, Task_1);    // Create tasks.

    OS_Task_Create(0, Task_2);   //

    OS_Task_Create(0, Task_3);     //


    OS_EI();                            // Enable interrupts

    OS_Run();                           // Running scheduler


}

// ENABLE CONSTANTS

//------------------------------------------------------------------------------

#define OS_ENABLE_TTIMERS           // Enable task timers (OS_Delay and OS_xxx_Wait_TO)

#endif
Edit: Use Code posting samples of code.. Make it easy for others to read and no Wink;

Hi, I also use MIkroC for Pic in several year. I would like to program RTOS for Pic by mikroC. You can see this link for instruction:
