GPIOTE_IRQHandler does not get executed

[GaneshKumar]

We are working on a device that communicates with the mobile device. There is a button in the device to wakeup. But this button does not wake up the device. On debugging we found that "GPIOTE_IRQHandler" is not getting called when there is a change in the port pin.

Below is the configuration:

NRF_GPIO->PIN_CNF[SWITCH0] = (GPIO_PIN_CNF_SENSE_Low << GPIO_PIN_CNF_SENSE_Pos)     \
          | (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos)       \
          | (GPIO_PIN_CNF_PULL_Disabled << GPIO_PIN_CNF_PULL_Pos)      \
          | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos)      \
          | (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);

Can you please advice why this interrupt does not get triggered???

Note: By default the port pin is pulled high and on a button press gets to logic Zero.

Hey,

Is the device you are talking about a Nordic development kit or a custom board?

[GaneshKumar]

It is custom board. We use the nrf52 development board to program the custom board

[Hakon]

Is it alright for you to send me the entire code? I can make the case private if you want.

[GaneshKumar]

The code can not be shared. We are analysing the issue will let you know the updates or any other info i could give.

Try to call

nrf_gpio_cfg_sense_input(PIN NUMBER, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_SENSE_LOW);
