APP_TIMER integrated with softdevice s132 gets error in init

[ziv123]

hi 

i have added a timer to a working code with softdevice, ble, uart and pwm for now.

when program starts it gets an error in the app_timer_init funcion  ' NRF_LOG_INFO("RTC: initialized."); '  throughs it

i m not sure why .. maybe related to some wrong definitios in the sdk_config but i am not sure which one

also, i have tried to add systick for a different porpose and it says " undefigned referance to nrfx_systich_init(), though i added the lib to the nrf drivers dir.. what am i missing ?

best regards

You are missing a ton of typos. And yes, the compiler (or linker in your case) has noticed that, too.

Thanks, that is very helpful  :/

(I rechecked this message for 'missing typos' not to heart your gentle feelings )

There are typos in every word here except "to". Which means you typed it instead of using copy and paste.

That is why I did not point the typo in the function name - which spells nrf_systick_init() by the way - directly. Cause I cannot tell if this is your actual code or not. In other words: We need to see your code directly and not some mis-typed lines.

In case the spelling was correct origianlly you might miss the corresponding .c file in your project/Makefile - or NRFX_SYSTICK_ENABLED is not set to 1.

very well 

the function i am using is -> ' nrf_drv_systick_init(); '

it goes to -> ' #define nrf_drv_systick_init        nrfx_systick_init ' 

and i can't serch farther so i guess some files are missing but i am not sure which 

any way i found the issue with the systick i hade to add some configurations system still somewhere in app_timer_init(); 

saying unknowen function at some address

You migh want to look up what the "grep" command line tool can do. Many IDE have a similar function integrated.

The nrfx_systick_init() function is implemented in "nrf_systick.c" and depends on NRFX_SYSTICK_ENABLED macro in sdk_config.h file.

Note that systick on NRF5x will not run in WFI/WFE condition (i.e. when the core sleeps) because the HF is clock not running.
