Is there TIMER + GPIOTE + PPI exampe ?

[bluemountain]

Hi Nordic, 

I want to implement a LED blinking like below pseudo code. 
I'd like to use Timer x n , GPIOTE, PPI since it doesn't consume any CPU time. 

for (10 times) {
    for (100 times) }
        LED_ON  : 0.4ms
        LED_OFF : 0.6ms
    }
   LED_OFF : 200ms
}   

Is there any example for Timer, GPIOTE, and PPI coding ?

You could just use a PWM peripherial for this task. Should be simple.

If you used the RTC timer, you would achieve a lot less current consumtion in the off time - because the HF(int) oscillator can sleep. It can't when TIMER or PWM was active.
