Methods
impl Current25Bricklet
[src]
impl Current25Bricklet
pub const DEVICE_IDENTIFIER: u16
[src]
pub const DEVICE_DISPLAY_NAME: &'static str
[src]
pub fn new(uid: &str, ip_connection: &IpConnection) -> Current25Bricklet | [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( | [src] |
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( | [src] |
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_current_callback_receiver(&self) -> ConvertingCallbackReceiver<i16> | [src] |
This receiver is triggered periodically with the period that is set by
set_current_callback_period
. The parameter is the current of the
sensor.
The get_current_callback_receiver
receiver is only triggered if the current has changed since the
last triggering.
pub fn get_analog_value_callback_receiver( | [src] |
This receiver is triggered periodically with the period that is set by
set_analog_value_callback_period
. The parameter is the analog value of the
sensor.
The get_analog_value_callback_receiver
receiver is only triggered if the current has changed since the
last triggering.
pub fn get_current_reached_callback_receiver( | [src] |
This receiver is triggered when the threshold as set by
set_current_callback_threshold
is reached.
The parameter is the current 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_analog_value_reached_callback_receiver( | [src] |
This receiver is triggered when the threshold as set by
set_analog_value_callback_threshold
is reached.
The parameter is the analog value 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_over_current_callback_receiver( | [src] |
This receiver is triggered when an over current is measured
(see is_over_current
).
pub fn get_current(&self) -> ConvertingReceiver<i16> | [src] |
Returns the current of the sensor. The value is in mA and between -25000mA and 25000mA.
If you want to get the current periodically, it is recommended to use the
get_current_callback_receiver
receiver and set the period with
set_current_callback_period
.
pub fn calibrate(&self) -> ConvertingReceiver<()> | [src] |
Calibrates the 0 value of the sensor. You have to call this function when there is no current present.
The zero point of the current sensor is depending on the exact properties of the analog-to-digital converter, the length of the Bricklet cable and the temperature. Thus, if you change the Brick or the environment in which the Bricklet is used, you might have to recalibrate.
The resulting calibration will be saved on the EEPROM of the Current Bricklet.
pub fn is_over_current(&self) -> ConvertingReceiver<bool> | [src] |
Returns true if more than 25A were measured.
Note
To reset this value you have to power cycle the Bricklet.
pub fn get_analog_value(&self) -> ConvertingReceiver<u16> | [src] |
Returns the value as read by a 12-bit analog-to-digital converter. The value is between 0 and 4095.
Note
The value returned by get_current
is averaged over several samples
to yield less noise, while get_analog_value
gives back raw
unfiltered analog values. The only reason to use get_analog_value
is,
if you need the full resolution of the analog-to-digital converter.
If you want the analog value periodically, it is recommended to use the
get_analog_value_callback_receiver
receiver and set the period with
set_analog_value_callback_period
.
pub fn set_current_callback_period(&self, period: u32) -> ConvertingReceiver<()> | [src] |
Sets the period in ms with which the get_current_callback_receiver
receiver is triggered
periodically. A value of 0 turns the receiver off.
The get_current_callback_receiver
receiver is only triggered if the current has changed since
the last triggering.
The default value is 0.
pub fn get_current_callback_period(&self) -> ConvertingReceiver<u32> | [src] |
Returns the period as set by set_current_callback_period
.
pub fn set_analog_value_callback_period( | [src] |
Sets the period in ms with which the get_analog_value_callback_receiver
receiver is triggered
periodically. A value of 0 turns the receiver off.
The get_analog_value_callback_receiver
receiver is only triggered if the analog value has
changed since the last triggering.
The default value is 0.
pub fn get_analog_value_callback_period(&self) -> ConvertingReceiver<u32> | [src] |
Returns the period as set by set_analog_value_callback_period
.
pub fn set_current_callback_threshold( | [src] |
Sets the thresholds for the get_current_reached_callback_receiver
receiver.
The following options are possible:
Option | Description |
---|---|
'x' | Receiver is turned off |
'o' | Receiver is triggered when the current is outside the min and max values |
'i' | Receiver is triggered when the current is inside the min and max values |
'<' | Receiver is triggered when the current is smaller than the min value (max is ignored) |
'>' | Receiver is triggered when the current is greater than the min value (max is ignored) |
The default value is ('x', 0, 0).
