<CUE>

Board BEHAVIOR for peripherals on TWELITE CUE.

It can handle accelerometers, magnetic sensors, and LEDs on the board.

• Accelerometer

• Magnetic sensor

• LEDs

void setup() {
  auto&& brd = the_twelite.board.use<CUE>();
}

Accelerometer

The MC3630 sensor member object (sns_MC3630) is defined.

Magnetic sensor

The sensor of the open/close sensor pal is a magnetic sensor, which is the only input for the interrupt of the two signal 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;

The PAL_MAG::PIN_SNS_NORTH is interrupted when the sensor detects an N-pole and the PAL_MAG::PIN_SNS_SOUTH is interrupted when the sensor detects an N-pole.

The following settings should be made before sleep

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

Check the IO of the waking factor upon waking.

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)

LED (D1) control.

The mode takes the following parameters. tick specifies the lighting time [ms], see the description of mode for details.

led_one_shot()

void led_one_shot(uint16_t tick)

Turns on the LED for a specified period of time. Cannot be used with set_led() function at the same time.

watchdog timer

Resets the external watchdog timer at startup, sleep wakeup, and after a certain period of time after startup.
