You can use it with softdevice without any changes. You can use TIMER1 or TIMER2. TIMER0 is used by softdevice and you can't use it.

Hi Nikita,

Thank you for the reply. I have tried to execute the code and its working fine. I could create a delay of 1us using the example project. Will it make any problem if i include this timer function to the ble_app_uart project? Which timer can i used if the code is to be included in to ble_app_uart project Timer0,1or2?

Thanks in advance, Shiju

You can use this example project as reference:

\Nordic Semiconductor\nRF51 SDK_v6.0.0.43681\Nordic\nrf51822\Board\nrf6310\timer_example

Hi Nikita,

What i am looking for is exact delay in microsecond.In my project i have used delay nrf_delay_us. It is using repeated NOP to create 1 microsecond delay. It may change the delay if another interrupts are triggered while using the nrf_delay_us loop.Is there any sample project which uses the this 1us timer delay implementation.

thanks in advance,
Shiju C G

What do you want to do with 1us interrupt? You won't be able to do anything with this frequent interrupts.

Well, in any case, you can use one of the timers that can be run with 16/32MHz HFCLK clock source.
