<ARIA>

For TWELITE ARIA
    This board behavior supports peripherals on the TWELITE ARIA.

    Enables access to the onboard accelerometer, magnetic sensor, and LED.

    • Temperature/Humidity Sensor
    • Magnetic Sensor
    • LED
    void setup() {
  auto&& brd = the_twelite.board.use<ARIA>();
}

    Temperature/Humidity Sensor

    A member object for the SHT4x sensor (sns_SHT4x) is defined.

    Magnetic Sensor

    The sensor used in the Door Sensor PAL is a magnetic sensor that only has two interrupt input lines.

    const uint8_t CUE::PIN_SNS_NORTH = 16;
const uint8_t CUE::PIN_SNS_OUT1 = 16;
const uint8_t CUE::PIN_SNS_SOUTH = 8;
const uint8_t CUE::PIN_SNS_OUT2 = 8;

    ARIA::PIN_SNS_NORTH triggers an interrupt when the sensor detects the north pole. ARIA::PIN_SNS_SOUTH also triggers an interrupt when the sensor detects the north pole.

    Before entering sleep, configure the pins as follows:

    pinMode(CUE::PIN_SNS_OUT1, PIN_MODE::WAKE_FALLING);
pinMode(CUE::PIN_SNS_OUT2, PIN_MODE::WAKE_FALLING);

    On wake-up, check the cause using:

    uint8_t b_north =
  the_twelite.is_wokeup_by_dio(CUE::PIN_SNS_NORTH);
uint8_t b_south =
  the_twelite.is_wokeup_by_dio(CUE::PIN_SNS_SOUTH);

    LED

    set_led()

    void set_led(uint8_t mode, uint16_t tick)

    Controls the LED (D1).

    mode accepts the following parameters. tick specifies the lighting duration in milliseconds [ms]. Refer to the mode descriptions for details.

    ValueDescription
    LED_TIMER::BLINKBlinks the LED. Toggles ON/OFF at intervals specified by tick [ms]. After waking from sleep, the timer resets and starts in the ON state.
    LED_TIMER::ON_RXTurns on the LED for the specified tick duration [ms] when a packet is received.
    LED_TIMER::ON_TX_COMPTurns on the LED for the specified tick duration [ms] when transmission completes.

    led_one_shot()

    void led_one_shot(uint16_t tick)

    Turns on the LED for a specified duration. Cannot be used simultaneously with set_led().

    Watchdog Timer

    Resets the external watchdog timer at startup, upon waking from sleep, and after a certain time has elapsed post-startup.
