API¶

To allow non-blocking usage, nearly every function of the Rust bindings returns a wrapper around a mpsc::Receiver. To block until the function has finished and get your result, call one of the receiver's recv variants. Those return either the result sent by the device, or any error occurred.

Functions returning a result directly will block until the device has finished processing the request.

All functions listed below are thread-safe, those which return a receiver are lock-free.

Basic Functions¶

pub fn TemperatureIrV2Bricklet::new(uid: &str, ip_connection: &IpConnection) → TemperatureIrV2Bricklet¶

Parameters:	uid – Type: &str ip_connection – Type: &IPConnection
Returns:	temperature_ir_v2 – Type: TemperatureIrV2Bricklet

Creates a new TemperatureIrV2Bricklet object with the unique device ID uid and adds it to the IPConnection ip_connection:

let temperature_ir_v2 = TemperatureIrV2Bricklet::new("YOUR_DEVICE_UID", &ip_connection);

This device object can be used after the IP connection has been connected.

pub fn TemperatureIrV2Bricklet::get_ambient_temperature(&self) → ConvertingReceiver<i16>¶

Returns:	temperature – Type: i16, Unit: 1/10 °C, Range: [-400 to 1250]

Returns the ambient temperature of the sensor.

If you want to get the value periodically, it is recommended to use the TemperatureIrV2Bricklet::get_ambient_temperature_callback_receiver callback. You can set the callback configuration with TemperatureIrV2Bricklet::set_ambient_temperature_callback_configuration.

pub fn TemperatureIrV2Bricklet::get_object_temperature(&self) → ConvertingReceiver<i16>¶

Returns:	temperature – Type: i16, Unit: 1/10 °C, Range: [-700 to 3800]

Returns the object temperature of the sensor, i.e. the temperature of the surface of the object the sensor is aimed at.

The temperature of different materials is dependent on their emissivity. The emissivity of the material can be set with TemperatureIrV2Bricklet::set_emissivity.

If you want to get the value periodically, it is recommended to use the TemperatureIrV2Bricklet::get_object_temperature_callback_receiver callback. You can set the callback configuration with TemperatureIrV2Bricklet::set_object_temperature_callback_configuration.

Advanced Functions¶

pub fn TemperatureIrV2Bricklet::set_emissivity(&self, emissivity: u16) → ConvertingReceiver<()>¶

Parameters:	emissivity – Type: u16, Unit: 1/65535, Range: [6553 to 2¹⁶ - 1], Default: 2¹⁶ - 1

Sets the emissivity that is used to calculate the surface temperature as returned by TemperatureIrV2Bricklet::get_object_temperature.

The emissivity is usually given as a value between 0.0 and 1.0. A list of emissivities of different materials can be found here.

The parameter of TemperatureIrV2Bricklet::set_emissivity has to be given with a factor of 65535 (16-bit). For example: An emissivity of 0.1 can be set with the value 6553, an emissivity of 0.5 with the value 32767 and so on.

Note

If you need a precise measurement for the object temperature, it is absolutely crucial that you also provide a precise emissivity.

The emissivity is stored in non-volatile memory and will still be used after a restart or power cycle of the Bricklet.

pub fn TemperatureIrV2Bricklet::get_emissivity(&self) → ConvertingReceiver<u16>¶

Returns:	emissivity – Type: u16, Unit: 1/65535, Range: [6553 to 2¹⁶ - 1], Default: 2¹⁶ - 1

Returns the emissivity as set by TemperatureIrV2Bricklet::set_emissivity.

pub fn TemperatureIrV2Bricklet::get_spitfp_error_count(&self) → ConvertingReceiver<SpitfpErrorCount>¶

Return Object:	error_count_ack_checksum – Type: u32, Range: [0 to 2³² - 1] error_count_message_checksum – Type: u32, Range: [0 to 2³² - 1] error_count_frame – Type: u32, Range: [0 to 2³² - 1] error_count_overflow – Type: u32, 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.

pub fn TemperatureIrV2Bricklet::set_status_led_config(&self, config: u8) → ConvertingReceiver<()>¶

Parameters:	config – Type: u8, 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:

TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_OFF = 0
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_ON = 1
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS = 3

pub fn TemperatureIrV2Bricklet::get_status_led_config(&self) → ConvertingReceiver<u8>¶

Returns:	config – Type: u8, Range: See constants, Default: 3

Returns the configuration as set by TemperatureIrV2Bricklet::set_status_led_config

The following constants are available for this function:

For config:

TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_OFF = 0
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_ON = 1
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
TEMPERATURE_IR_V2_BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS = 3

pub fn TemperatureIrV2Bricklet::get_chip_temperature(&self) → ConvertingReceiver<i16>¶

Returns:	temperature – Type: i16, 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.

pub fn TemperatureIrV2Bricklet::reset(&self) → ConvertingReceiver<()>¶

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!

pub fn TemperatureIrV2Bricklet::get_identity(&self) → ConvertingReceiver<Identity>¶

Return Object:

Return Object:	uid – Type: String, Length: up to 8 connected_uid – Type: String, Length: up to 8 position – Type: char, Range: ['a' to 'h', 'z'] hardware_version – Type: [u8; 3] 0: major – Type: u8, Range: [0 to 255] 1: minor – Type: u8, Range: [0 to 255] 2: revision – Type: u8, Range: [0 to 255] firmware_version – Type: [u8; 3] 0: major – Type: u8, Range: [0 to 255] 1: minor – Type: u8, Range: [0 to 255] 2: revision – Type: u8, Range: [0 to 255] device_identifier – Type: u16, Range: [0 to 2¹⁶ - 1]

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at 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¶

pub fn TemperatureIrV2Bricklet::set_ambient_temperature_callback_configuration(&self, period: u32, value_has_to_change: bool, option: char, min: i16, max: i16) → ConvertingReceiver<()>¶

Parameters:	period – Type: u32, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 value_has_to_change – Type: bool, Default: false option – Type: char, Range: See constants, Default: 'x' min – Type: i16, Unit: 1/10 °C, Range: [-2¹⁵ to 2¹⁵ - 1], Default: 0 max – Type: i16, Unit: 1/10 °C, Range: [-2¹⁵ to 2¹⁵ - 1], Default: 0

The period is the period with which the TemperatureIrV2Bricklet::get_ambient_temperature_callback_receiver 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 TemperatureIrV2Bricklet::get_ambient_temperature_callback_receiver 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:

TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_OFF = 'x'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_OUTSIDE = 'o'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_INSIDE = 'i'

TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_GREATER = '>'

pub fn TemperatureIrV2Bricklet::set_object_temperature_callback_configuration(&self, period: u32, value_has_to_change: bool, option: char, min: i16, max: i16) → ConvertingReceiver<()>¶

Parameters:	period – Type: u32, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 value_has_to_change – Type: bool, Default: false option – Type: char, Range: See constants, Default: 'x' min – Type: i16, Unit: 1/10 °C, Range: [-2¹⁵ to 2¹⁵ - 1], Default: 0 max – Type: i16, Unit: 1/10 °C, Range: [-2¹⁵ to 2¹⁵ - 1], Default: 0

The period is the period with which the TemperatureIrV2Bricklet::get_object_temperature_callback_receiver callback is triggered periodically. A value of 0 turns the callback off.

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 TemperatureIrV2Bricklet::get_object_temperature_callback_receiver 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

Returns the callback configuration as set by TemperatureIrV2Bricklet::set_object_temperature_callback_configuration.

The following constants are available for this function:

For option:

TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_OFF = 'x'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_OUTSIDE = 'o'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_INSIDE = 'i'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_SMALLER = '<'
TEMPERATURE_IR_V2_BRICKLET_THRESHOLD_OPTION_GREATER = '>'

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the corresponding get_*_callback_receiver function, which returns a receiver for callback events.

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.

pub fn TemperatureIrV2Bricklet::get_ambient_temperature_callback_receiver(&self) → ConvertingCallbackReceiver<i16>¶

Event:	temperature – Type: i16, Unit: 1/10 °C, Range: [-400 to 1250]

Receivers created with this function receive Ambient Temperature events.

This callback is triggered periodically according to the configuration set by TemperatureIrV2Bricklet::set_ambient_temperature_callback_configuration.

The received variable is the same as TemperatureIrV2Bricklet::get_ambient_temperature.

pub fn TemperatureIrV2Bricklet::get_object_temperature_callback_receiver(&self) → ConvertingCallbackReceiver<i16>¶

Event:	temperature – Type: i16, Unit: 1/10 °C, Range: [-700 to 3800]

Receivers created with this function receive Object Temperature events.

This callback is triggered periodically according to the configuration set by TemperatureIrV2Bricklet::set_object_temperature_callback_configuration.

The received variable is the same as TemperatureIrV2Bricklet::get_object_temperature.

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.

pub fn TemperatureIrV2Bricklet::get_api_version(&self) → [u8; 3]¶

Return Object:	api_version – Type: [u8; 3] 0: major – Type: u8, Range: [0 to 255] 1: minor – Type: u8, Range: [0 to 255] 2: revision – Type: u8, 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.

pub fn TemperatureIrV2Bricklet::get_response_expected(&mut self, function_id: u8) → bool¶

Parameters:	function_id – Type: u8, 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 TemperatureIrV2Bricklet::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 sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_CONFIGURATION = 2
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_OBJECT_TEMPERATURE_CALLBACK_CONFIGURATION = 6
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_EMISSIVITY = 9
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_STATUS_LED_CONFIG = 239
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_RESET = 243
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_WRITE_UID = 248

pub fn TemperatureIrV2Bricklet::set_response_expected(&mut self, function_id: u8, response_expected: bool) → ()¶

Parameters:	function_id – Type: u8, 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:

TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_AMBIENT_TEMPERATURE_CALLBACK_CONFIGURATION = 2
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_OBJECT_TEMPERATURE_CALLBACK_CONFIGURATION = 6
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_SET_EMISSIVITY = 9

TEMPERATURE_IR_V2_BRICKLET_FUNCTION_RESET = 243
TEMPERATURE_IR_V2_BRICKLET_FUNCTION_WRITE_UID = 248

pub fn TemperatureIrV2Bricklet::set_response_expected_all(&mut self, response_expected: bool) → ()¶

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.

pub fn TemperatureIrV2Bricklet::set_bootloader_mode(&self, mode: u8) → ConvertingReceiver<u8>¶

Parameters:	mode – Type: u8, Range: See constants
Returns:	status – Type: u8, 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:

TEMPERATURE_IR_V2_BRICKLET_BOOTLOADER_MODE_BOOTLOADER = 0
TEMPERATURE_IR_V2_BRICKLET_BOOTLOADER_MODE_FIRMWARE = 1
TEMPERATURE_IR_V2_BRICKLET_BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2

TEMPERATURE_IR_V2_BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

pub fn TemperatureIrV2Bricklet::set_write_firmware_pointer(&self, pointer: u32) → ConvertingReceiver<()>¶

Parameters:	pointer – Type: u32, Unit: 1 B, Range: [0 to 2³² - 1]

Sets the firmware pointer for TemperatureIrV2Bricklet::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.

pub fn TemperatureIrV2Bricklet::write_firmware(&self, data: [u8; 64]) → ConvertingReceiver<u8>¶

Parameters:	data – Type: [u8; 64], Range: [0 to 255]
Returns:	status – Type: u8, Range: [0 to 255]

Writes 64 Bytes of firmware at the position as written by TemperatureIrV2Bricklet::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.

pub fn TemperatureIrV2Bricklet::write_uid(&self, uid: u32) → ConvertingReceiver<()>¶

Parameters:	uid – Type: u32, 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.

pub fn TemperatureIrV2Bricklet::read_uid(&self) → ConvertingReceiver<u32>¶

Returns:	uid – Type: u32, Range: [0 to 2³² - 1]

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

Constants¶

pub const TemperatureIrV2Bricklet::DEVICE_IDENTIFIER¶

This constant is used to identify a Temperature IR Bricklet 2.0.

The TemperatureIrV2Bricklet::get_identity function and the IpConnection::get_enumerate_callback_receiver callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

pub const TemperatureIrV2Bricklet::DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a Temperature IR Bricklet 2.0.
