Please tell me how to set the button processing

Since the accuracy of the timer interrupt will decrease if two timers are not used, the key processing was created to be processed within the timer interrupt.

Can you also share the full debug log so we can make sure this is still the bsp_init() function returning error 4 (NO_MEM)?

If you in fact have an unused timer, then I don't see why this function would return the NO_MEM error.

Best regards,

[Timer Usage]
1) timer0: SoftDevice
2) timer1: 0.5m interrupt
3) timer2: unused
4) timer3: ADC
5) timer4: PWM

Can you please share some details on what your application does exactly, what timers it use for what, etc.?

Can you also share the full debug log so we can make sure this is still the bsp_init() function returning error 4 (NO_MEM)?

Best regards,

Since "timer1" and "timer2" were used for timer interrupts, I changed it to work only with "timer1", but the state did not change.

Is it still the bsp_init() that returns error 4 here as well? That must mean that some other peripheral is using Timer 2 already in your application. Please make sure only one peripheral use each timer.

I set timer 2 to unused state and checked again, but the behavior did not change and error 4 occurred.

If you are using a specific timer for key processing, please tell us which timer you are using for key processing.

Error 4 points to there not being enough memory. When the bsp_init() function returns this error, it points to the maximum number of timers already being reached, so my guess is that your application is already using all available timers. The nRF52832 has 5 timers available, and the SoftDevice requires one, and multiple other peripherals require timers, so it seems like you've just reached the maximum number.
