Implementations

impl ThermalImagingBricklet

pub const DEVICE_IDENTIFIER: u16 = 278u16

pub const DEVICE_DISPLAY_NAME: &'static str = "Thermal Imaging Bricklet"

pub fn new(uid: &str, ip_connection: &IpConnection) -> ThermalImagingBricklet

Creates an object with the unique device ID uid. This object can then be used after the IP Connection ip_connection is connected.

pub fn get_response_expected(
    &mut self,
    fun: ThermalImagingBrickletFunction
) -> Result<bool, GetResponseExpectedError>

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.

See set_response_expected for the list of function ID constants available for this function.

pub fn set_response_expected(
    &mut self,
    fun: ThermalImagingBrickletFunction,
    response_expected: bool
) -> Result<(), SetResponseExpectedError>

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.

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

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

• FFC Imminent: This state is entered 2 seconds prior to initiating FFC.
• FFC In Progress: Flat field correction is started (shutter moves in front of lens and back). Takes about 1 second.
• FFC Complete: Shutter is in waiting position again, FFC done.

Temperature warning bits:

• Index 0: Shutter lockout (if true shutter is locked out because temperature is outside -10°C to +65°C)

pub fn set_spotmeter_config(
    &self,
    region_of_interest: [u8; 4]
) -> ConvertingReceiver<()>

Sets the spotmeter region of interest. The 4 values are

• Index 0: Column start (has to be smaller then Column end).
• Index 1: Row start (has to be smaller then Row end).
• Index 2: Column end (has to be smaller then 80).
• Index 3: Row end (has to be smaller then 60).

The spotmeter statistics can be read out with Get Statistics.

The default region of interest is (39, 29, 40, 30).

pub fn get_spotmeter_config(&self) -> ConvertingReceiver<[u8; 4]>

Returns the spotmeter config as set by Set Spotmeter Config.

pub fn set_high_contrast_config(
    &self,
    region_of_interest: [u8; 4],
    dampening_factor: u16,
    clip_limit: [u16; 2],
    empty_counts: u16
) -> ConvertingReceiver<()>

Sets the high contrast region of interest, dampening factor, clip limit and empty counts. This config is only used in high contrast mode (see Set Image Transfer Config).

The high contrast region of interest consists of four values:

• Index 0: Column start (has to be smaller or equal then Column end).
• Index 1: Row start (has to be smaller then Row end).
• Index 2: Column end (has to be smaller then 80).
• Index 3: Row end (has to be smaller then 60).

The algorithm to generate the high contrast image is applied to this region.

Dampening Factor: This parameter is the amount of temporal dampening applied to the HEQ (history equalization) transformation function. An IIR filter of the form::

(N / 256) * previous + ((256 - N) / 256) * current

is applied, and the HEQ dampening factor represents the value N in the equation, i.e., a value that applies to the amount of influence the previous HEQ transformation function has on the current function. The lower the value of N the higher the influence of the current video frame whereas the higher the value of N the more influence the previous damped transfer function has.

Clip Limit Index 0 (AGC HEQ Clip Limit Low): This parameter defines an artificial population that is added to every non-empty histogram bin. In other words, if the Clip Limit Low is set to L, a bin with an actual population of X will have an effective population of L + X. Any empty bin that is nearby a populated bin will be given an artificial population of L. The effect of higher values is to provide a more linear transfer function; lower values provide a more non-linear (equalized) transfer function.

Clip Limit Index 1 (AGC HEQ Clip Limit High): This parameter defines the maximum number of pixels allowed to accumulate in any given histogram bin. Any additional pixels in a given bin are clipped. The effect of this parameter is to limit the influence of highly-populated bins on the resulting HEQ transformation function.

Empty Counts: This parameter specifies the maximum number of pixels in a bin that will be interpreted as an empty bin. Histogram bins with this number of pixels or less will be processed as an empty bin.

The default values are

• Region Of Interest = (0, 0, 79, 59),
• Dampening Factor = 64,
• Clip Limit = (4800, 512) and
• Empty Counts = 2.

pub fn set_image_transfer_config(&self, config: u8) -> ConvertingReceiver<()>

The necessary bandwidth of this Bricklet is too high to use getter/receiver or high contrast/temperature image at the same time. You have to configure the one you want to use, the Bricklet will optimize the internal configuration accordingly.

Corresponding functions:

• Manual High Contrast Image: Get High Contrast Image.
• Manual Temperature Image: Get Temperature Image.
• Receiver High Contrast Image: get_high_contrast_image_callback_receiver receiver.

pub fn set_write_firmware_pointer(&self, pointer: u32) -> ConvertingReceiver<()>

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.

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

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.

pub fn set_status_led_config(&self, config: u8) -> ConvertingReceiver<()>

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.

Associated constants:

pub fn get_chip_temperature(&self) -> ConvertingReceiver<i16>

Returns the temperature in °C 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 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 write_uid(&self, uid: u32) -> ConvertingReceiver<()>

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 read_uid(&self) -> ConvertingReceiver<u32>

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

pub fn get_identity(&self) -> ConvertingReceiver<Identity>

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’ or ‘d’.

The device identifier numbers can be found here. |device_identifier_constant|
