impl MotorizedLinearPotiBricklet
pub const DEVICE_IDENTIFIER: u16 = 267u16
pub const DEVICE_DISPLAY_NAME: &'static str = "Motorized Linear Poti Bricklet"
sourcepub fn new(
uid: &str,
ip_connection: &IpConnection
) -> MotorizedLinearPotiBricklet
pub fn new(
uid: &str,
ip_connection: &IpConnection
) -> MotorizedLinearPotiBricklet
Creates an object with the unique device ID uid
. This object can then be used after the IP Connection ip_connection
is connected.
sourcepub fn get_response_expected(
&mut self,
fun: MotorizedLinearPotiBrickletFunction
) -> Result<bool, GetResponseExpectedError>
pub fn get_response_expected(
&mut self,
fun: MotorizedLinearPotiBrickletFunction
) -> 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.
sourcepub fn set_response_expected(
&mut self,
fun: MotorizedLinearPotiBrickletFunction,
response_expected: bool
) -> Result<(), SetResponseExpectedError>
pub fn set_response_expected(
&mut self,
fun: MotorizedLinearPotiBrickletFunction,
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.
sourcepub fn set_response_expected_all(&mut self, response_expected: bool)
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.
sourcepub fn get_position_callback_receiver(&self) -> ConvertingCallbackReceiver<u16>
pub fn get_position_callback_receiver(&self) -> ConvertingCallbackReceiver<u16>
This receiver is triggered periodically according to the configuration set by
set_position_callback_configuration
.
The parameter is the same as get_position
.
sourcepub fn get_position_reached_callback_receiver(
&self
) -> ConvertingCallbackReceiver<u16>
pub fn get_position_reached_callback_receiver(
&self
) -> ConvertingCallbackReceiver<u16>
This receiver is triggered if a new position as set by
set_motor_position
is reached.
The parameter is the current position.
sourcepub fn get_position(&self) -> ConvertingReceiver<u16>
pub fn get_position(&self) -> ConvertingReceiver<u16>
Returns the position of the linear potentiometer. The value is between 0 (slider down) and 100 (slider up).
If you want to get the value periodically, it is recommended to use the
get_position_callback_receiver
receiver. You can set the receiver configuration
with set_position_callback_configuration
.
sourcepub fn set_position_callback_configuration(
&self,
period: u32,
value_has_to_change: bool,
option: char,
min: u16,
max: u16
) -> ConvertingReceiver<()>
pub fn set_position_callback_configuration(
&self,
period: u32,
value_has_to_change: bool,
option: char,
min: u16,
max: u16
) -> ConvertingReceiver<()>
The period in ms is the period with which the get_position_callback_receiver
receiver is triggered
periodically. A value of 0 turns the receiver off.
If the value has to change
-parameter is set to true, the receiver is only
triggered after the value has changed. If the value didn’t change
within the period, the receiver is triggered immediately on change.
If it is set to false, the receiver is continuously triggered with the period, independent of the value.
It is furthermore possible to constrain the receiver with thresholds.
The option
-parameter together with min/max sets a threshold for the get_position_callback_receiver
receiver.
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 receiver is triggered with the fixed period.
The default value is (0, false, ‘x’, 0, 0).

sourcepub fn set_motor_position(
&self,
position: u16,
drive_mode: u8,
hold_position: bool
) -> ConvertingReceiver<()>
pub fn set_motor_position(
&self,
position: u16,
drive_mode: u8,
hold_position: bool
) -> ConvertingReceiver<()>
Sets the position of the potentiometer. The motorized potentiometer will immediately start to approach the position. Depending on the chosen drive mode, the position will either be reached as fast as possible or in a slow but smooth motion.
The position has to be between 0 (slider down) and 100 (slider up).
If you set the hold position parameter to true, the position will automatically be retained. If a user changes the position of the potentiometer, it will automatically drive back to the original set point.
If the hold position parameter is set to false, the potentiometer can be changed again by the user as soon as the set point was reached once.

- MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_FAST
- MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_SMOOTH
sourcepub fn get_motor_position(&self) -> ConvertingReceiver<MotorPosition>
pub fn get_motor_position(&self) -> ConvertingReceiver<MotorPosition>
Returns the last motor position as set by set_motor_position
. This is not
the current position (use get_position
to get the current position). This
is the last used set point and configuration.
The position reached parameter is true if the position has been reached at one point. The position may have been changed again in the meantime by the user.

- MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_SMOOTH
sourcepub fn calibrate(&self) -> ConvertingReceiver<()>
pub fn calibrate(&self) -> ConvertingReceiver<()>
Starts a calibration procedure. The potentiometer will be driven to the extreme points to calibrate the potentiometer.
The calibration is saved in flash, it does not have to be called on every start up.
The Motorized Linear Poti Bricklet is already factory-calibrated during testing at Tinkerforge.
sourcepub fn set_position_reached_callback_configuration(
&self,
enabled: bool
) -> ConvertingReceiver<()>
pub fn set_position_reached_callback_configuration(
&self,
enabled: bool
) -> ConvertingReceiver<()>
Enables/Disables get_position_reached_callback_receiver
receiver.
By default the receiver is enabled.
sourcepub fn get_position_reached_callback_configuration(
&self
) -> ConvertingReceiver<bool>
pub fn get_position_reached_callback_configuration(
&self
) -> ConvertingReceiver<bool>
Returns the get_position_reached_callback_receiver
receiver configuration
as set by set_position_reached_callback_configuration
.
sourcepub fn get_spitfp_error_count(&self) -> ConvertingReceiver<SpitfpErrorCount>
pub fn get_spitfp_error_count(&self) -> ConvertingReceiver<SpitfpErrorCount>
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.
sourcepub fn set_bootloader_mode(&self, mode: u8) -> ConvertingReceiver<u8>
pub fn set_bootloader_mode(&self, mode: u8) -> ConvertingReceiver<u8>
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.

sourcepub fn set_write_firmware_pointer(&self, pointer: u32) -> ConvertingReceiver<()>
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.
sourcepub fn write_firmware(&self, data: [u8; 64]) -> ConvertingReceiver<u8>
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.
sourcepub fn set_status_led_config(&self, config: u8) -> ConvertingReceiver<()>
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.

sourcepub fn get_chip_temperature(&self) -> ConvertingReceiver<i16>
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.
sourcepub fn reset(&self) -> ConvertingReceiver<()>
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!
sourcepub fn write_uid(&self, uid: u32) -> ConvertingReceiver<()>
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.
sourcepub fn read_uid(&self) -> ConvertingReceiver<u32>
pub fn read_uid(&self) -> ConvertingReceiver<u32>
Returns the current UID as an integer. Encode as Base58 to get the usual string version.
sourcepub fn get_identity(&self) -> ConvertingReceiver<Identity>
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|
