Measures reflectivity of a surface
Methods
impl LineBricklet
[src]
pub const DEVICE_IDENTIFIER: u16
[src]
pub const DEVICE_DISPLAY_NAME: &'static str
[src]
pub fn new<T: GetRequestSender>(uid: &str, req_sender: T) -> LineBricklet
[src]
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: LineBrickletFunction
) -> Result<bool, GetResponseExpectedError>
[src]
&mut self,
fun: LineBrickletFunction
) -> 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: LineBrickletFunction,
response_expected: bool
) -> Result<(), SetResponseExpectedError>
[src]
&mut self,
fun: LineBrickletFunction,
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)
[src]
Changes the response expected flag for all setter and callback configuration functions of this device at once.
pub fn get_api_version(&self) -> [u8; 3]
[src]
Returns the version of the API definition (major, minor, revision) 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 get_reflectivity_callback_receiver(
&self
) -> ConvertingCallbackReceiver<u16>
[src]
&self
) -> ConvertingCallbackReceiver<u16>
This receiver is triggered periodically with the period that is set by
set_reflectivity_callback_period
. The parameter is the
reflectivity of the sensor.
The get_reflectivity_callback_receiver
receiver is only triggered if the reflectivity has
changed since the last triggering.
pub fn get_reflectivity_reached_callback_receiver(
&self
) -> ConvertingCallbackReceiver<u16>
[src]
&self
) -> ConvertingCallbackReceiver<u16>
This receiver is triggered when the threshold as set by
set_reflectivity_callback_threshold
is reached.
The parameter is the reflectivity of the sensor.
If the threshold keeps being reached, the receiver is triggered periodically
with the period as set by set_debounce_period
.
pub fn get_reflectivity(&self) -> ConvertingReceiver<u16>
[src]
Returns the currently measured reflectivity. The reflectivity is a value between 0 (not reflective) and 4095 (very reflective).
Usually black has a low reflectivity while white has a high reflectivity.
If you want to get the reflectivity periodically, it is recommended
to use the get_reflectivity_callback_receiver
receiver and set the period with
set_reflectivity_callback_period
.
pub fn set_reflectivity_callback_period(
&self,
period: u32
) -> ConvertingReceiver<()>
[src]
&self,
period: u32
) -> ConvertingReceiver<()>
Sets the period with which the get_reflectivity_callback_receiver
receiver is triggered
periodically. A value of 0 turns the receiver off.
The get_reflectivity_callback_receiver
receiver is only triggered if the reflectivity has
changed since the last triggering.
pub fn get_reflectivity_callback_period(&self) -> ConvertingReceiver<u32>
[src]
Returns the period as set by set_reflectivity_callback_period
.
pub fn set_reflectivity_callback_threshold(
&self,
option: char,
min: u16,
max: u16
) -> ConvertingReceiver<()>
[src]
&self,
option: char,
min: u16,
max: u16
) -> ConvertingReceiver<()>
Sets the thresholds for the get_reflectivity_reached_callback_receiver
receiver.
The following options are possible:
Option | Description |
---|---|
'x' | Receiver is turned off |
'o' | Receiver is triggered when the reflectivity is outside the min and max values |
'i' | Receiver is triggered when the reflectivity is inside the min and max values |
'<' | Receiver is triggered when the reflectivity is smaller than the min value (max is ignored) |
'>' | Receiver is triggered when the reflectivity is greater than the min value (max is ignored) |

pub fn get_reflectivity_callback_threshold(
&self
) -> ConvertingReceiver<ReflectivityCallbackThreshold>
[src]
&self
) -> ConvertingReceiver<ReflectivityCallbackThreshold>
Returns the threshold as set by set_reflectivity_callback_threshold
.
Associated constants:
- LINE_BRICKLET_THRESHOLD_OPTION_OFF
- LINE_BRICKLET_THRESHOLD_OPTION_OUTSIDE
- LINE_BRICKLET_THRESHOLD_OPTION_INSIDE

pub fn set_debounce_period(&self, debounce: u32) -> ConvertingReceiver<()>
[src]
Sets the period with which the threshold receiver
is triggered, if the threshold
keeps being reached.
pub fn get_debounce_period(&self) -> ConvertingReceiver<u32>
[src]
Returns the debounce period as set by set_debounce_period
.
pub fn get_identity(&self) -> ConvertingReceiver<Identity>
[src]
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|
