Hi folks,

I try to do create timer. Therefore i want to adding some files in blinky project. So here is some screen shot. Thats about debug error. First i used SDK 15.2 than i tried to added nrfx_drv_timer.c files. I didn't find SDK files. Than I tried other files that drv_rtc.c and i encounter errors that second picture. Where is my mistakes. I am very confused. I know someone read that want to help me.

If you only want to add a timer ,just  reference the  Demo of nRF5_SDK_15.2.0_9412b96\examples\peripheral\timer, remember don't use timer0 which is used by softdevice.

Thanks for your answer lemon.

But actually i want to add different timer in blinky project. I checked peripheral examples. If i be succeed i would control some gpio.

Maybe you can realize the app_timer module . It's easier to use , and the hrs demo has the usage of app_timer module
