Increment Counter on Button Clicked

[Rihab]

Hello everyone,
i need to increment a counter each time my button on the nrf534DK is pressed 
i'm using sdk v 1.7.1 . 
is there a simple way to do it or a function which supports this 
do you have any example that can guide me through, so that i can implement and increment my counter each time the button is pressed .

i already have my button example running perfectly 
i just need to implement a counter that increments by 1 each time the button is pressed
i did some researches and i saw that RTC counter need to be used 

do you have an example on that or can you guide me through to get it done 
the image below is showing how my button is pressed 
1-button pressed ( printk("***************Button pressed at %" PRIu32 "\n", k_cycle_get_32());  k_cycle_get_32->Current hardware clock up-counter (in cycles)  ) 
2-get bme data
3-get Mpu data


knowing the details can you help me please implement the counter
feel free to provide me with any example that can help me 
i really appreciate your help in advance 

very thankful 

kindly,

Rihab

Do you need a HW counter or will a SW counter suffice?

[Rihab]

i already have the hardware button i need to make a counter each time it's pressed 
to reply to your question i think i need both 

[Rihab]

for now the button is returning the hardware clock up-counter 
so i'm aware of when it's pressed 
i think a software implementation will suffice

Then you need to declare a global variable and increment that instead of/in addition to incrementing the global variable.
