Hi,

How does your main.c and prj.conf look like now?

After adding the suuggested lines to prj.conf file,

CONFIG_NRFX_TIMER0=y
CONFIG_NRFX_TIMER1=y

ther is build error as shown in image.

Try these timer instances instead:

static const nrfx_timer_t m_timer_count = NRFX_TIMER_INSTANCE(2);

static const nrfx_timer_t m_timer_read  = NRFX_TIMER_INSTANCE(3);

And set this in prj.conf

CONFIG_NRFX_TIMER2=y
CONFIG_NRFX_TIMER3=y

I copied some code from the link of example given by you as in attached text file. When, build the error shown in image occurs.

Hi, I have already used a Timer using Zephyr Kernel s below:

K_WORK_DEFINE(my_work, my_work_handler);

void my_timer_handler(struct k_timer *dummy)
{
k_work_submit(&my_work);
}

K_TIMER_DEFINE(my_timer, my_timer_handler, NULL);

void my_work_handler(struct k_work *work)

{

}

k_timer_start(&my_timer, K_SECONDS(4), K_SECONDS(30));

Form above it is not clear that which Timer has been used in it ?

Hi,

I believe I have some code here that does what you describe:
