while loop for led blinking not working

[MARTIN FR]

Hello,

I have created the simple software usign NRF51DK to make the led blink for 5 times by using while loop just to make the other part of my software my aim of this program is to create pwm pulses for five times so i am started doing the simple software by using LED

Issue: when i flashed the program the led blink for the first and only one time and then cleared completely but my aim is to blink (on and off for five times)

could anyone please tell me what mistakes in my logic? or possible things i have to take care inorder to make the led blink for 5 times

int i=0;

while(i<5)

{

								 // Start LED here
               nrf_gpio_pin_clear(LED_1);
								  nrf_delay_ms(50);
								  nrf_gpio_pin_set(LED_1);
								i++;

							}

Now it's working because now you clear(turn off the led) the pin, wait 50ms, set (turn on the led) the pin, wait 50 ms and clear the pin again. This way the led is off 50ms, and on 50ms, five times.

Before you were clearing the pin, wait 50ms, set the pin and clear the pin again. This way your led is off 50ms, and on just a cycle of the program that is to fast for you to see.

Hope this helped.

Thank you so much

hello i just tested the same program for toggling the led for five times but the LED turnON and OFF only for three times but as per my condition it should toggle for five times right but what is wrong in my toggling logic

    static int i=0;             
    while(i<5)
    { 
        nrf_gpio_pin_toggle(LED_1); 
        nrf_delay_ms(500);    
        i++;
    }
    nrf_gpio_pin_set(LED_1);
}

Is that really a serious question? 5 toggles followed by one on is is On-Off-On-Off-On-On which is 3 flashes in total.

This really has nothing whatsoever to do with Nordic either.

the main reason for this question i have explained clearly above but once again to create (PWM pulses) produce different sounds on the piezo buzzer with changing the delay
