Power button multi usage

[spatcho]

Good day,

I would like to keep using the power button on / off functionality, and also use the button to i.e. turn on an oled screen. Per example 4s press to turn off, 2s press to turn on, and short press to catch specific code. I see there is interrupt available but if my use case is possible, could I have a short code example ?

Hi there, In my case, I use long press to turn on/off and short press to wakeup/sleep, try twist your code inside,

1st, make a bool pmu_flag = false;

bool pmu_flag = false; 

2nd, custom function,

void setFlag(void) {
  pmu_flag = true;
}

3rd, setup the interrupt in setup(),

  pinMode(PMU_INPUT_PIN, INPUT_PULLUP);  // the shared pin 6 of SoC and PMU.  While DC1 power supply remained, SoC can be wakeup by this pin.  And PMU can also be forced power off by long press this pin.
  attachInterrupt(PMU_INPUT_PIN, setFlag, FALLING);
  // Close other IRQs
  PMU.disableIRQ(XPOWERS_AXP2101_ALL_IRQ);
  // Clear all interrupt flags
  PMU.clearIrqStatus();
  // Enable the required interrupt function
  PMU.enableIRQ(XPOWERS_AXP2101_PKEY_SHORT_IRQ);  //POWER KEY

4th, put a trigger in loop();

if (pmu_flag) {
    pmu_flag = false;
    // Get PMU Interrupt Status Register
    uint32_t status = PMU.getIrqStatus();
    if (PMU.isPekeyShortPressIrq()) {
      // your codes here...
    }
  }

It worked, thank you
