GPIOTE current issue in nRF51422 v2

[Atlas]

Hi

I used SDK v5.2, SD : s310 v1.0.0 and nRF51422 v2 (QFAA E0).

The power consumption is too high when I used GPIOTE to do interrupt.

Disable GPIOTE:

The current value:

BLE ADV and ANT open channel : ~1.3mA

Connect : 0.5uA

Enable GPIOTE:

BLE ADV and ANT open channel : ~2.3mA

Connect : 1.5uA

I saw the current is 22uA when use GPIOTE in the datasheet v2.1.

please advise.

#define INT_PIN 24

void GPIOTE_IRQHandler(void)

{

// Event causing the interrupt must be cleared.

if ((NRF_GPIOTE->EVENTS_IN[0] == 1) && (NRF_GPIOTE->INTENSET &

  GPIOTE_INTENSET_IN0_Msk))   

{

  NRF_GPIOTE->EVENTS_IN[0] = 0;   

}

}

void gpiote_init(void)

{

nrf_gpio_cfg_input(INT_PIN, BUTTON_PULL);    

NVIC_ClearPendingIRQ(GPIOTE_IRQn);   

NVIC_SetPriority(GPIOTE_IRQn, APP_IRQ_PRIORITY_LOW);   

NVIC_EnableIRQ(GPIOTE_IRQn);    

nrf_gpiote_event_config  (0,INT_PIN,NRF_GPIOTE_POLARITY_HITOLO);  

NRF_GPIOTE->INTENSET  = 1; 

}

I put gpiote_init() after buttons_init(); in main();

THanks.

Hi I did not use GPIOTE to do wakeup pin function. There is a interrupt pin from my sensor to connect with nRF51422. Please advise.

Thanks. BR Atlas
