hello everyone:
i use interrupt to handle button.and when i init it,the power is increase about 200uA. i think the interrupt will not increase the power
void gpiote_event_handler(uint32_t event_pins_low_to_high, uint32_t event_pins_high_to_low)
{
// SEGGER_RTT_printf(0,"GPIO interrupt ---\r\n");
if (event_pins_low_to_high & (1 << CHECK_SIM)) { //
CHECK_SIM_Handle();//SEGGER_RTT_printf(0,"CHECK_SIM in\r\n");
}
if (event_pins_high_to_low & (1 << CHECK_SIM)) { //
CHECK_SIM_Handle();//SEGGER_RTT_printf(0,"CHECK_SIM out\r\n");
}
if (event_pins_high_to_low & (1 << BUTTON_PIN)) { //
Touch_Key_Handle();
}
if ((event_pins_high_to_low & (1 << STDBY)) || (event_pins_low_to_high & (1 << STDBY))) {
ChargeState_Handle();
}
if ((event_pins_high_to_low & (1 << CHRG)) || (event_pins_low_to_high & (1 << CHRG))) {
ChargeState_Handle();
}
}
static void buttons_init()
{
uint32_t err_code;
uint32_t low_to_high_bitmask = (1<<CHECK_SIM)|(1 << STDBY) |(1 << CHRG);//|0x00000000;
uint32_t high_to_low_bitmask = (1<<CHECK_SIM)|(1 << BUTTON_PIN)|(1 << STDBY)|(1 << CHRG);
// Configure BUTTON1 with SENSE enabled
nrf_gpio_cfg_input(CHECK_SIM, NRF_GPIO_PIN_PULLUP);
nrf_gpio_cfg_input(BUTTON_PIN, NRF_GPIO_PIN_PULLUP);//touch key//NRF_GPIO_PIN_NOPULL
nrf_gpio_cfg_input(STDBY, NRF_GPIO_PIN_NOPULL);//chrg
nrf_gpio_cfg_input(CHRG, NRF_GPIO_PIN_NOPULL);//chrg
