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.

really i have connected the buzzer sperately for both pins but only one pin is making beep sound that too it is not loud enough and also i have one question does the buzzer make beep sound after pressing the button ? because am trying to make that function like that and also pin 6 ,pin7 collectively provides 5mA current because am not gettign that function working properly
