Looking to implement "one shot timer" , however, not sure does it work on the SDK 17.1.0 , because it explicitly points to the 15.2 ?

very helpfull :)

few questions:

1. when working with single shot do we need to stop time ? or is there a way to un instence the timer if it is used only once in the program

2. what will happen if a timer is started again by interrupt for example when it is not yet finished its first count .. will the timer handler be called 2 times or only once ?.

Hi,
Is there a version of this page that works with SDK 15.3.0? I am getting errors with the new SDK on the nRF52DK (pca10040), both using the Segger embedded studio and the armgcc makefile.
To be as clean as possible, I also switched to your github project github.com/.../nrf5-application-timer-tutorial and switched to the completed branch.
Both from the IDE and command line, I get:
arm-none-eabi-gcc: error: /opt/nRF5_SDK_15.3.0/modules/nrfx/drivers/src/nrfx_power_clock.c: No such file or directory
Indeed, SDK 15.3.0 does not appear to include this file.

Removing the corresponding line from the Makefile makes the code run through and I am even seeminly able to flash the device, but for some reason the devkit still runs the previous code. The IDE, in contrast, complains that some softdevice is missing.

Would it be possible to update this page and the github timer tutorial project to work with the current SDK 15.3.0?
Thanks a lot

All links in this tutorial point to DocLib which does not exist anymore. Could this be fixed please?

Hi,

I have followed the tutorial in order to create a repetitive timer, but my code crashes at function "nrf_drv_clock_lfclk_request" when the macro "CRITICAL_REGION_EXIT();" is executed. Specifically when "app_util_enable_irq();" function is executed.

Any idea about what can be the issue plese?

Thanks.

i dont know if anyone is even reading what we write here but here is what i found out about my problem...

the functions that are throwing undefined error:
undefined reference to `nrf_drv_clock_init'
undefined reference to `nrf_drv_clock_lfclk_request'
are both defined inside the nrf_drv_clock.c file... when you open that file on line 44 it says:
"#if NRF_MODULE_ENABLED(NRF_CLOCK)" and everything after that line is grayed out and disabled... this means that NRF_CLOCK module is not enabled... downloaded the example provided here "Example project application_timer_tutorial (SDK 15.2)" and its working, i copied the whole content of the sdk_config.h of the example into my sdk_config.h file in my project, but then i got other errors...
can you please provide us with complete instructions or explanation how and which configurations do we need to include in our sdk_config.h file to be able to run the Application Timer successfully?

i am using SDK15.2, followed all the steps explained in "SDK 15.2 version: The Application Timer" part of this tutorial and when i try to compile i get this errors:
Output/twi_scanner_pca10040 Debug/Obj/main.o: In function `lfclk_request':
undefined reference to `nrf_drv_clock_init'
undefined reference to `nrf_drv_clock_lfclk_request'

I am using modified "twi_scanner_pca10040" example from the SDK...

Hi, I tried with FreeRTOS + softblink example. Don't seem to work.
