STM CircleOS forum / LEDs blinking issue

clemzzz · 2010-06-01 14:19:17

Hi,
I noticed something with the 2 controllable LEDs.

When I set them to "blinking" mode, it's not blinking when another program is running.

For instance : I'd like to make the green led blink when data is received (via IR). As I wait, it's not blinking.

Code:

enum MENU_code fRecv()
    {
    int i;
    LED_Set(LED_GREEN,LED_BLINKING_HI);
    DRAW_DisplayString(5,5,"Receiving...", 13);
     
    wait(5);    //wait for 5 seconds
    
    LED_Set(LED_GREEN,LED_OFF);
    DRAW_Clear();
    return Application_Ini();
    }

Maybe is it dealing with the active/passive waiting...
Do you have any idea of how I could do ?

Thanks

Use time check in application handler instead of wait. While 'Wait'ing you only allowing system to execute application handler so led handler never gets executed.

Use time checks or interrupts!
(it will also save your battery)

Effectively, the instruction LED_Set only changes the functionning mode of the LEDs. The blink of the LEDs is done by the LED handler. If your application does not give the hand to CircleOS, the LED will not blink.
