API

ncir2_0.init_i2c_address(0x5A)

• Initialize I2C communication address

print(ncir2_0.button_status())

• Retrieve button state (pressed or released)

print(ncir2_0.buzzer_control())

• Retrieve buzzer enable status (on or off)

print(ncir2_0.buzzer_duty())

• Retrieve buzzer duty cycle (duty cycle value 0-255, higher value indicates louder sound)

print(ncir2_0.buzzer_freq())

• Retrieve buzzer frequency value (default 4000 Hz)

print(ncir2_0.read_device_status(0xFE))

• Retrieve device firmware version or I2C address (default I2C address is 0x5A)

print(ncir2_0.chip_temperature_measure())

• Retrieve device temperature value (in ℃)

print(ncir2_0.emissivity_measure())

• Retrieve reflectance of an object's surface

print(ncir2_0.rgb_led())

• Retrieve RGB LED color (RGB values range from 0-255)

print(ncir2_0.temperature_measure())

• Retrieve temperature value (redundant, but assuming it's for clarity)

print(ncir2_0.temp_buzzer_duty(0x44))

• Set buzzer duty cycle at maximum and minimum temperature thresholds (duty cycle value 0-255, higher value indicates louder sound)

print(ncir2_0.temp_buzzer_freq(0x40))

• Retrieve buzzer frequency at maximum or minimum temperature thresholds (default 4000 Hz, higher value indicates sharper sound)

print(ncir2_0.temp_alarm_interval(0x42))

• Retrieve buzzer high-low level intervals at maximum or minimum temperature thresholds (default low: 100, high: 204)

print(ncir2_0.temp_alarm_led(0x30))

• Retrieve LED color at maximum or minimum temperature thresholds (RGB values range from 0-255)

print(ncir2_0.temperature_threshold(0x20))

• Retrieve maximum and minimum temperature thresholds (default set to minimum 10°C, maximum 37°C)

ncir2_0.save_config_setting()

• Save current configuration settings

ncir2_0.buzzer_duty(80)

• Retrieve buzzer duty cycle (duty cycle value 0-255, higher value indicates louder sound) (redundant, but for completeness)

ncir2_0.buzzer_freq(4000)

• Set buzzer frequency (default 4000 Hz, higher value indicates louder sound, but note: frequency does not directly correlate to loudness, it affects pitch)

ncir2_0.buzzer_control(0x01)

• Set buzzer enable status (on or off)

ncir2_0.emissivity_measure(0.95)

• Set reflectance (skin reflectance is 0.95)

ncir2_0.write_i2c_address(0x5A)

• Set device's I2C address (default 0x5A)

ncir2_0.rgb_led(50, 50, 50)

• Set RGB LED color values (RGB values range from 0-255)

ncir2_0.temp_buzzer_duty(0x44, 80)

• Set buzzer duty cycle at maximum and minimum temperature thresholds (duty cycle value 0-255, higher value indicates louder sound) (redundant, but for consistency)

ncir2_0.temp_buzzer_freq(0x40, 4000)

• Set buzzer intervals at maximum or minimum temperature thresholds (higher value indicates faster response)

ncir2_0.temp_alarm_interval(0x42, 100)

• (Duplicate entry) Set buzzer intervals at maximum or minimum temperature thresholds (higher value indicates faster response)

ncir2_0.temp_alarm_led(0x30, 50, 50, 50)

• Set buzzer frequency at maximum or minimum temperature thresholds (default 4000 Hz, higher value indicates sharper sound)

ncir2_0.temperature_threshold(0x20, 25)

• Set LED RGB color values at maximum or minimum temperature thresholds (RGB values range from 0-255)
