API

Generally, every function of the Python bindings can throw an tinkerforge.ip_connection.Error exception that has a value and a description property. value can have different values:

  • Error.TIMEOUT = -1
  • Error.NOT_ADDED = -6 (unused since Python bindings version 2.0.0)
  • Error.ALREADY_CONNECTED = -7
  • Error.NOT_CONNECTED = -8
  • Error.INVALID_PARAMETER = -9
  • Error.NOT_SUPPORTED = -10
  • Error.UNKNOWN_ERROR_CODE = -11
  • Error.STREAM_OUT_OF_SYNC = -12
  • Error.INVALID_UID = -13
  • Error.NON_ASCII_CHAR_IN_SECRET = -14

All functions listed below are thread-safe.

Basic Functions

BrickletAmbientLightV3(uid, ipcon)
Parameters:
  • uid – Type: str
  • ipcon – Type: IPConnection
Returns:
  • ambient_light_v3 – Type: BrickletAmbientLightV3

Creates an object with the unique device ID uid:

ambient_light_v3 = BrickletAmbientLightV3("YOUR_DEVICE_UID", ipcon)

This object can then be used after the IP Connection is connected (see examples above).

BrickletAmbientLightV3.get_illuminance()
Returns:
  • illuminance – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1]

Returns the illuminance of the ambient light sensor. The measurement range goes up to about 100000lux, but above 64000lux the precision starts to drop. The illuminance is given in lux/100, i.e. a value of 450000 means that an illuminance of 4500lux is measured.

An illuminance of 0lux indicates that the sensor is saturated and the configuration should be modified, see set_configuration().

If you want to get the value periodically, it is recommended to use the CALLBACK_ILLUMINANCE callback. You can set the callback configuration with set_illuminance_callback_configuration().

BrickletAmbientLightV3.set_configuration(illuminance_range, integration_time)
Parameters:
  • illuminance_range – Type: int, Range: See constants, Default: 3
  • integration_time – Type: int, Range: See constants, Default: 2
Returns:
  • None

Sets the configuration. It is possible to configure an illuminance range between 0-600lux and 0-64000lux and an integration time between 50ms and 400ms.

The unlimited illuminance range allows to measure up to about 100000lux, but above 64000lux the precision starts to drop.

A smaller illuminance range increases the resolution of the data. A longer integration time will result in less noise on the data.

If the actual measure illuminance is out-of-range then the current illuminance range maximum +0.01lux is reported by get_illuminance() and the CALLBACK_ILLUMINANCE callback. For example, 800001 for the 0-8000lux range.

With a long integration time the sensor might be saturated before the measured value reaches the maximum of the selected illuminance range. In this case 0lux is reported by get_illuminance() and the CALLBACK_ILLUMINANCE callback.

If the measurement is out-of-range or the sensor is saturated then you should configure the next higher illuminance range. If the highest range is already in use, then start to reduce the integration time.

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

  • ACK checksum errors,
  • message checksum errors,
  • framing errors and
  • overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

BrickletAmbientLightV3.set_bootloader_mode(mode)
Parameters:
  • mode – Type: int, Range: See constants
Returns:
  • status – Type: int, Range: See constants

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

The following constants are available for this function:

For mode:

  • BrickletAmbientLightV3.BOOTLOADER_MODE_BOOTLOADER = 0

Returns the current bootloader mode, see set_bootloader_mode().

The following constants are available for this function:

For mode:

  • BrickletAmbientLightV3.BOOTLOADER_MODE_BOOTLOADER = 0
  • BrickletAmbientLightV3.BOOTLOADER_MODE_FIRMWARE = 1

  • BrickletAmbientLightV3.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
  • BrickletAmbientLightV3.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4
BrickletAmbientLightV3.set_write_firmware_pointer(pointer)
Parameters:
  • pointer – Type: int, Unit: 1 B, Range: [0 to 232 - 1]
Returns:
  • None

Sets the firmware pointer for write_firmware(). The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletAmbientLightV3.write_firmware(data)
Parameters:
  • data – Type: [int, ...], Length: 64, Range: [0 to 255]
Returns:
  • status – Type: int, Range: [0 to 255]

Writes 64 Bytes of firmware at the position as written by set_write_firmware_pointer() before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletAmbientLightV3.set_status_led_config(config)
Parameters:
  • config – Type: int, Range: See constants, Default: 3
Returns:
  • None

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

The following constants are available for this function:

For config:

  • BrickletAmbientLightV3.STATUS_LED_CONFIG_OFF = 0
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_ON = 1
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_SHOW_STATUS = 3
BrickletAmbientLightV3.get_status_led_config()
Returns:
  • config – Type: int, Range: See constants, Default: 3

Returns the configuration as set by set_status_led_config()

The following constants are available for this function:

For config:

  • BrickletAmbientLightV3.STATUS_LED_CONFIG_OFF = 0
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_ON = 1
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • BrickletAmbientLightV3.STATUS_LED_CONFIG_SHOW_STATUS = 3
BrickletAmbientLightV3.get_chip_temperature()
Returns:
  • temperature – Type: int, Unit: 1 °C, Range: [-215 to 215 - 1]

Returns the temperature as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

BrickletAmbientLightV3.reset()
Returns:
  • None

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

BrickletAmbientLightV3.write_uid(uid)
Parameters:
  • uid – Type: int, Range: [0 to 232 - 1]
Returns:
  • None

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

BrickletAmbientLightV3.read_uid()
Returns:
  • uid – Type: int, Range: [0 to 232 - 1]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

BrickletAmbientLightV3.get_identity()
Return Object:
  • uid – Type: str, Length: up to 8
  • connected_uid – Type: str, Length: up to 8
  • position – Type: chr, Range: ["a" to "h", "i", "z"]
  • hardware_version – Type: [int, ...], Length: 3
    • 0: major – Type: int, Range: [0 to 255]
    • 1: minor – Type: int, Range: [0 to 255]
    • 2: revision – Type: int, Range: [0 to 255]
  • firmware_version – Type: [int, ...], Length: 3
    • 0: major – Type: int, Range: [0 to 255]
    • 1: minor – Type: int, Range: [0 to 255]
    • 2: revision – Type: int, Range: [0 to 255]
  • device_identifier – Type: int, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). The Raspberry Pi HAT (Zero) Brick is always at position 'i' and the Bricklet connected to an Isolator Bricklet is always as position 'z'.

The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.

Callback Configuration Functions

BrickletAmbientLightV3.register_callback(callback_id, function)
Parameters:
  • callback_id – Type: int
  • function – Type: callable
Returns:
  • None

Registers the given function with the given callback_id.

The available callback IDs with corresponding function signatures are listed below.

BrickletAmbientLightV3.set_illuminance_callback_configuration(period, value_has_to_change, option, min, max)
Parameters:
  • period – Type: int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • value_has_to_change – Type: bool, Default: False
  • option – Type: chr, Range: See constants, Default: "x"
  • min – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1], Default: 0
  • max – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1], Default: 0
Returns:
  • None

The period is the period with which the CALLBACK_ILLUMINANCE callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

It is furthermore possible to constrain the callback with thresholds.

The option-parameter together with min/max sets a threshold for the CALLBACK_ILLUMINANCE callback.

The following options are possible:

Option Description
'x' Threshold is turned off
'o' Threshold is triggered when the value is outside the min and max values
'i' Threshold is triggered when the value is inside or equal to the min and max values
'<' Threshold is triggered when the value is smaller than the min value (max is ignored)
'>' Threshold is triggered when the value is greater than the min value (max is ignored)

If the option is set to 'x' (threshold turned off) the callback is triggered with the fixed period.

The following constants are available for this function:

For option:

  • BrickletAmbientLightV3.THRESHOLD_OPTION_OFF = "x"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_OUTSIDE = "o"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_INSIDE = "i"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_SMALLER = "<"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_GREATER = ">"
BrickletAmbientLightV3.get_illuminance_callback_configuration()
Return Object:
  • period – Type: int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • value_has_to_change – Type: bool, Default: False
  • option – Type: chr, Range: See constants, Default: "x"
  • min – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1], Default: 0
  • max – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1], Default: 0

Returns the callback configuration as set by set_illuminance_callback_configuration().

The following constants are available for this function:

For option:

  • BrickletAmbientLightV3.THRESHOLD_OPTION_OFF = "x"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_OUTSIDE = "o"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_INSIDE = "i"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_SMALLER = "<"
  • BrickletAmbientLightV3.THRESHOLD_OPTION_GREATER = ">"

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the register_callback() function of the device object. The first parameter is the callback ID and the second parameter the callback function:

def my_callback(param):
    print(param)

ambient_light_v3.register_callback(BrickletAmbientLightV3.CALLBACK_EXAMPLE, my_callback)

The available constants with inherent number and type of parameters are described below.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

BrickletAmbientLightV3.CALLBACK_ILLUMINANCE
Callback Parameters:
  • illuminance – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1]

This callback is triggered periodically according to the configuration set by set_illuminance_callback_configuration().

The parameter is the same as get_illuminance().

Virtual Functions

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

BrickletAmbientLightV3.get_api_version()
Return Object:
  • api_version – Type: [int, ...], Length: 3
    • 0: major – Type: int, Range: [0 to 255]
    • 1: minor – Type: int, Range: [0 to 255]
    • 2: revision – Type: int, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

BrickletAmbientLightV3.get_response_expected(function_id)
Parameters:
  • function_id – Type: int, Range: See constants
Returns:
  • response_expected – Type: bool

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by set_response_expected(). For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

  • BrickletAmbientLightV3.FUNCTION_SET_ILLUMINANCE_CALLBACK_CONFIGURATION = 2
  • BrickletAmbientLightV3.FUNCTION_SET_CONFIGURATION = 5
  • BrickletAmbientLightV3.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletAmbientLightV3.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletAmbientLightV3.FUNCTION_RESET = 243
  • BrickletAmbientLightV3.FUNCTION_WRITE_UID = 248
BrickletAmbientLightV3.set_response_expected(function_id, response_expected)
Parameters:
  • function_id – Type: int, Range: See constants
  • response_expected – Type: bool
Returns:
  • None

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

  • BrickletAmbientLightV3.FUNCTION_SET_ILLUMINANCE_CALLBACK_CONFIGURATION = 2
  • BrickletAmbientLightV3.FUNCTION_SET_CONFIGURATION = 5
  • BrickletAmbientLightV3.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletAmbientLightV3.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletAmbientLightV3.FUNCTION_RESET = 243
  • BrickletAmbientLightV3.FUNCTION_WRITE_UID = 248
BrickletAmbientLightV3.set_response_expected_all(response_expected)
Parameters:
  • response_expected – Type: bool
Returns:
  • None

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Constants

BrickletAmbientLightV3.DEVICE_IDENTIFIER

This constant is used to identify a Ambient Light Bricklet 3.0.

The get_identity() function and the IPConnection.CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

BrickletAmbientLightV3.DEVICE_DISPLAY_NAME

This constant represents the human readable name of a Ambient Light Bricklet 3.0.
