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 MotorizedLinearPotiBricklet::new(uid: &str, ip_connection: &IpConnection) → MotorizedLinearPotiBricklet¶

Parameters:	uid – Type: &str ip_connection – Type: &IPConnection
Returns:	motorized_linear_poti – Type: MotorizedLinearPotiBricklet

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

let motorized_linear_poti = MotorizedLinearPotiBricklet::new("YOUR_DEVICE_UID", &ip_connection);

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

pub fn MotorizedLinearPotiBricklet::get_position(&self) → ConvertingReceiver<u16>¶

Returns:	position – Type: u16, Range: [0 to 100]

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 MotorizedLinearPotiBricklet::get_position_callback_receiver callback. You can set the callback configuration with MotorizedLinearPotiBricklet::set_position_callback_configuration.

pub fn MotorizedLinearPotiBricklet::set_motor_position(&self, position: u16, drive_mode: u8, hold_position: bool) → ConvertingReceiver<()>¶

Parameters:	position – Type: u16, Range: [0 to 100] drive_mode – Type: u8, Range: See constants hold_position – Type: bool

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.

The following constants are available for this function:

For drive_mode:

MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_FAST = 0
MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_SMOOTH = 1

pub fn MotorizedLinearPotiBricklet::get_motor_position(&self) → ConvertingReceiver<MotorPosition>¶

Return Object:	position – Type: u16, Range: [0 to 100] drive_mode – Type: u8, Range: See constants hold_position – Type: bool position_reached – Type: bool

Returns the last motor position as set by MotorizedLinearPotiBricklet::set_motor_position. This is not the current position (use MotorizedLinearPotiBricklet::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.

The following constants are available for this function:

For drive_mode:

MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_FAST = 0
MOTORIZED_LINEAR_POTI_BRICKLET_DRIVE_MODE_SMOOTH = 1

Advanced Functions¶

pub fn MotorizedLinearPotiBricklet::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.

pub fn MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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:

MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_OFF = 0
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_ON = 1
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS = 3

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

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

Returns the configuration as set by MotorizedLinearPotiBricklet::set_status_led_config

The following constants are available for this function:

For config:

MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_OFF = 0
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_ON = 1
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
MOTORIZED_LINEAR_POTI_BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS = 3

pub fn MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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]

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]

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', '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 MotorizedLinearPotiBricklet::set_position_callback_configuration(&self, period: u32, value_has_to_change: bool, option: char, min: u16, max: u16) → 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: u16, Range: [0 to 2¹⁶ - 1], Default: 0 max – Type: u16, Range: [0 to 2¹⁶ - 1], Default: 0

The period is the period with which the MotorizedLinearPotiBricklet::get_position_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 MotorizedLinearPotiBricklet::get_position_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:

MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_OFF = 'x'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_OUTSIDE = 'o'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_INSIDE = 'i'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_SMALLER = '<'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_GREATER = '>'

pub fn MotorizedLinearPotiBricklet::get_position_callback_configuration(&self) → ConvertingReceiver<PositionCallbackConfiguration>¶

Return Object:	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: u16, Range: [0 to 2¹⁶ - 1], Default: 0 max – Type: u16, Range: [0 to 2¹⁶ - 1], Default: 0

Returns the callback configuration as set by MotorizedLinearPotiBricklet::set_position_callback_configuration.

The following constants are available for this function:

For option:

MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_OFF = 'x'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_OUTSIDE = 'o'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_INSIDE = 'i'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_SMALLER = '<'
MOTORIZED_LINEAR_POTI_BRICKLET_THRESHOLD_OPTION_GREATER = '>'

pub fn MotorizedLinearPotiBricklet::set_position_reached_callback_configuration(&self, enabled: bool) → ConvertingReceiver<()>¶

Parameters:	enabled – Type: bool, Default: true

Enables/Disables MotorizedLinearPotiBricklet::get_position_reached_callback_receiver callback.

pub fn MotorizedLinearPotiBricklet::get_position_reached_callback_configuration(&self) → ConvertingReceiver<bool>¶

Returns:	enabled – Type: bool, Default: true

Returns the MotorizedLinearPotiBricklet::get_position_reached_callback_receiver callback configuration as set by MotorizedLinearPotiBricklet::set_position_reached_callback_configuration.

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 MotorizedLinearPotiBricklet::get_position_callback_receiver(&self) → ConvertingCallbackReceiver<u16>¶

Event:	position – Type: u16, Range: [0 to 100]

Receivers created with this function receive Position events.

This callback is triggered periodically according to the configuration set by MotorizedLinearPotiBricklet::set_position_callback_configuration.

The received variable is the same as MotorizedLinearPotiBricklet::get_position.

pub fn MotorizedLinearPotiBricklet::get_position_reached_callback_receiver(&self) → ConvertingCallbackReceiver<u16>¶

Event:	position – Type: u16, Range: [0 to 100]

Receivers created with this function receive Position Reached events.

This callback is triggered if a new position as set by MotorizedLinearPotiBricklet::set_motor_position is reached.

The received variable is the current position.

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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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:

MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_POSITION_CALLBACK_CONFIGURATION = 2
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_MOTOR_POSITION = 5
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_CALIBRATE = 7
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_POSITION_REACHED_CALLBACK_CONFIGURATION = 8
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_STATUS_LED_CONFIG = 239
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_RESET = 243
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_WRITE_UID = 248

pub fn MotorizedLinearPotiBricklet::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:

MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_POSITION_CALLBACK_CONFIGURATION = 2
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_MOTOR_POSITION = 5
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_CALIBRATE = 7
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_POSITION_REACHED_CALLBACK_CONFIGURATION = 8
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_SET_STATUS_LED_CONFIG = 239
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_RESET = 243
MOTORIZED_LINEAR_POTI_BRICKLET_FUNCTION_WRITE_UID = 248

pub fn MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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:

MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_BOOTLOADER = 0
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE = 1
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

For status:

MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_OK = 0
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_INVALID_MODE = 1
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_NO_CHANGE = 2
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_ENTRY_FUNCTION_NOT_PRESENT = 3
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_DEVICE_IDENTIFIER_INCORRECT = 4
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_STATUS_CRC_MISMATCH = 5

pub fn MotorizedLinearPotiBricklet::get_bootloader_mode(&self) → ConvertingReceiver<u8>¶

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

Returns the current bootloader mode, see MotorizedLinearPotiBricklet::set_bootloader_mode.

The following constants are available for this function:

For mode:

MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_BOOTLOADER = 0
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE = 1
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
MOTORIZED_LINEAR_POTI_BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

pub fn MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::DEVICE_IDENTIFIER¶

This constant is used to identify a Motorized Linear Poti Bricklet.

The MotorizedLinearPotiBricklet::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 MotorizedLinearPotiBricklet::DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a Motorized Linear Poti Bricklet.
