API¶

Functions that return multiple values return them in an associative array.

Basic Functions¶

class BrickletUVLightV2(string $uid, IPConnection $ipcon)¶

Parameters:	$uid – Type: string $ipcon – Type: IPConnection
Returns:	$uv_light_v2 – Type: BrickletUVLightV2

Creates an object with the unique device ID $uid:

<?php   $uv_light_v2 = new BrickletUVLightV2('YOUR_DEVICE_UID', $ipcon);   ?>

This object can then be used after the IP Connection is connected.

int BrickletUVLightV2::getUVA()¶

Returns:	$uva – Type: int, Unit: 1/10 mW/m², Range: [-1 to 2³¹ - 1]

Returns the UVA intensity of the sensor. The sensor has not weighted the intensity with the erythemal action spectrum to get the skin-affecting irradiation. Therefore, you cannot just divide the value by 250 to get the UVA index. To get the UV index use getUVI().

If the sensor is saturated, then -1 is returned, see setConfiguration().

If you want to get the intensity periodically, it is recommended to use the CALLBACK_UVA callback and set the period with setUVACallbackConfiguration().

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

int BrickletUVLightV2::getUVB()¶

Returns:	$uvb – Type: int, Unit: 1/10 mW/m², Range: [-1 to 2³¹ - 1]

Returns the UVB intensity of the sensor. The sensor has not weighted the intensity with the erythemal action spectrum to get the skin-affecting irradiation. Therefore, you cannot just divide the value by 250 to get the UVB index. To get the UV index use getUVI().

If the sensor is saturated, then -1 is returned, see setConfiguration().

If you want to get the intensity periodically, it is recommended to use the CALLBACK_UVB callback and set the period with setUVBCallbackConfiguration().

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

int BrickletUVLightV2::getUVI()¶

Returns:	$uvi – Type: int, Unit: 1/10 , Range: [-1 to 2³¹ - 1]

Returns the UV index of the sensor, the index is given in 1/10.

If the sensor is saturated, then -1 is returned, see setConfiguration().

If you want to get the intensity periodically, it is recommended to use the CALLBACK_UVI callback and set the period with setUVICallbackConfiguration().

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

Advanced Functions¶

void BrickletUVLightV2::setConfiguration(int $integration_time)¶

Parameters:	$integration_time – Type: int, Range: See constants, Default: 3

Sets the configuration of the sensor. The integration time can be configured between 50 and 800 ms. With a shorter integration time the sensor reading updates more often but contains more noise. With a longer integration the sensor reading contains less noise but updates less often.

With a longer integration time (especially 800 ms) and a higher UV intensity the sensor can be saturated. If this happens the UVA/UVB/UVI readings are all -1. In this case you need to choose a shorter integration time.

The following constants are available for this function:

For $integration_time:

BrickletUVLightV2::INTEGRATION_TIME_50MS = 0
BrickletUVLightV2::INTEGRATION_TIME_100MS = 1
BrickletUVLightV2::INTEGRATION_TIME_200MS = 2
BrickletUVLightV2::INTEGRATION_TIME_400MS = 3
BrickletUVLightV2::INTEGRATION_TIME_800MS = 4

int BrickletUVLightV2::getConfiguration()¶

Returns:	$integration_time – Type: int, Range: See constants, Default: 3

Returns the configuration as set by setConfiguration().

The following constants are available for this function:

For $integration_time:

BrickletUVLightV2::INTEGRATION_TIME_100MS = 1
BrickletUVLightV2::INTEGRATION_TIME_200MS = 2
BrickletUVLightV2::INTEGRATION_TIME_400MS = 3
BrickletUVLightV2::INTEGRATION_TIME_800MS = 4

array BrickletUVLightV2::getSPITFPErrorCount()¶

Return Array:	'error_count_ack_checksum' – Type: int, Range: [0 to 2³² - 1] 'error_count_message_checksum' – Type: int, Range: [0 to 2³² - 1] 'error_count_frame' – Type: int, Range: [0 to 2³² - 1] 'error_count_overflow' – Type: int, Range: [0 to 2³² - 1]

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.

void BrickletUVLightV2::setStatusLEDConfig(int $config)¶

Parameters:	$config – Type: int, Range: See constants, Default: 3

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:

BrickletUVLightV2::STATUS_LED_CONFIG_OFF = 0
BrickletUVLightV2::STATUS_LED_CONFIG_ON = 1
BrickletUVLightV2::STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2

int BrickletUVLightV2::getStatusLEDConfig()¶

Returns:	$config – Type: int, Range: See constants, Default: 3

Returns the configuration as set by setStatusLEDConfig()

The following constants are available for this function:

int BrickletUVLightV2::getChipTemperature()¶

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.

void BrickletUVLightV2::reset()¶

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!

It is furthermore possible to constrain the callback with thresholds.

The option-parameter together with min/max sets a threshold for the CALLBACK_UVA 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)

BrickletUVLightV2::THRESHOLD_OPTION_GREATER = '>'

Callbacks¶

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

<?php

function myCallback($param)
{
    echo $param . "\n";
}

$uv_light_v2->registerCallback(BrickletUVLightV2::CALLBACK_EXAMPLE, 'myCallback');

?>

The available constants with corresponding function signatures 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.

int BrickletUVLightV2::CALLBACK_UVA¶

<?php   void callback(int $uva [, mixed $user_data])   ?>

Callback Parameters:	$uva – Type: int, Unit: 1/10 mW/m², Range: [-1 to 2³¹ - 1] $user_data – Type: mixed

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

The parameter is the same as getUVA().

int BrickletUVLightV2::CALLBACK_UVB¶

<?php   void callback(int $uvb [, mixed $user_data])   ?>

Callback Parameters:	$uvb – Type: int, Unit: 1/10 mW/m², Range: [-1 to 2³¹ - 1] $user_data – Type: mixed

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

The parameter is the same as getUVB().

int BrickletUVLightV2::CALLBACK_UVI¶

<?php   void callback(int $uvi [, mixed $user_data])   ?>

Callback Parameters:	$uvi – Type: int, Unit: 1/10 , Range: [-1 to 2³¹ - 1] $user_data – Type: mixed

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

The parameter is the same as getUVI().

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.

array BrickletUVLightV2::getAPIVersion()¶

Return Array:	$api_version – Type: array(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.

bool BrickletUVLightV2::getResponseExpected(int $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 setResponseExpected(). 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 sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For $function_id:

BrickletUVLightV2::FUNCTION_SET_UVA_CALLBACK_CONFIGURATION = 2
BrickletUVLightV2::FUNCTION_SET_UVB_CALLBACK_CONFIGURATION = 6

BrickletUVLightV2::FUNCTION_RESET = 243
BrickletUVLightV2::FUNCTION_WRITE_UID = 248

void BrickletUVLightV2::setResponseExpected(int $function_id, bool $response_expected)¶

Parameters:	$function_id – Type: int, Range: See constants $response_expected – Type: bool

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.

The following constants are available for this function:

For $function_id:

BrickletUVLightV2::FUNCTION_SET_UVA_CALLBACK_CONFIGURATION = 2
BrickletUVLightV2::FUNCTION_SET_UVB_CALLBACK_CONFIGURATION = 6

void BrickletUVLightV2::setResponseExpectedAll(bool $response_expected)¶

Parameters:	$response_expected – Type: bool

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

Internal Functions¶

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

int BrickletUVLightV2::setBootloaderMode(int $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.

Returns the current bootloader mode, see setBootloaderMode().

The following constants are available for this function:

For $mode:

BrickletUVLightV2::BOOTLOADER_MODE_BOOTLOADER = 0
BrickletUVLightV2::BOOTLOADER_MODE_FIRMWARE = 1
BrickletUVLightV2::BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
BrickletUVLightV2::BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
BrickletUVLightV2::BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

void BrickletUVLightV2::setWriteFirmwarePointer(int $pointer)¶

Parameters:	$pointer – Type: int, Unit: 1 B, Range: [0 to 2³² - 1]

Sets the firmware pointer for writeFirmware(). 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.

int BrickletUVLightV2::writeFirmware(array $data)¶

Parameters:	$data – Type: array(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 setWriteFirmwarePointer() 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.

void BrickletUVLightV2::writeUID(int $uid)¶

Parameters:	$uid – Type: int, Range: [0 to 2³² - 1]

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.

int BrickletUVLightV2::readUID()¶

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.

Constants¶

int BrickletUVLightV2::DEVICE_IDENTIFIER¶

This constant is used to identify a UV Light Bricklet 2.0.

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

string BrickletUVLightV2::DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a UV Light Bricklet 2.0.
