Hi prabhudurai,

still havent gone through your code, but had a quick look. I saw this below code in your init_gpio() function

NRF_GPIO->PIN_CNF[6] = (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos);

This is wrong as you are setting every other bits to '0' and only setting the drive strength. With this the pin will be configured as input. To do this correctly, you need to do this below

NRF_GPIO->PIN_CNF[6] &= ~(GPIO_PIN_CNF_DRIVE_Msk); // reset drive setting
NRF_GPIO->PIN_CNF[6] |= (GPIO_PIN_CNF_DRIVE_H0D1 << GPIO_PIN_CNF_DRIVE_Pos); // set to high drive

you need to do this for pin settings 7 also.

When you are using the same button for recognizing 3 seconds push and 5 seconds push then it is normal that it is getting confused when you 3 seconds are expired.

t You can change your logic like this. When you press the button, start the 3 second timer. When the 3 sec timer expires and its callback is called, check if the button is still pressed, If it is still shows that the button is pressed, start 2 seconds timer. When the two seconds timer expires and the callback is called, check again if the button is being pressed. If it is not pressed, then it was 3 seconds push and start the buzzer. If it is still being pressed it is a 5 second push so stop the buzzer.
