                             throws TinkerforgeException
        Sets the acceleration and deacceleration of the stepper motor. An acceleration of 1000 means, that every second the velocity is increased by 1000 *steps/s*. For example: If the current velocity is 0 and you want to accelerate to a velocity of 8000 *steps/s* in 10 seconds, you should set an acceleration of 800 *steps/s²*. An acceleration/deacceleration of 0 means instantaneous acceleration/deacceleration (not recommended)

      • fullBrake

        public void fullBrake()
                       throws TinkerforgeException
        Executes an active full brake. \warning This function is for emergency purposes, where an immediate brake is necessary. Depending on the current velocity and the strength of the motor, a full brake can be quite violent. Call stop() if you just want to stop the motor.

        public void setCurrentPosition​(int position)
                                throws TinkerforgeException
        Sets the current steps of the internal step counter. This can be used to set the current position to 0 when some kind of starting position is reached (e.g. when a CNC machine reaches a corner).

        TinkerforgeException
      • setStepConfiguration

        public void setStepConfiguration​(short stepResolution,

                                  throws TinkerforgeException
        Sets the step resolution from full-step up to 1/256-step. If interpolation is turned on, the Silent Stepper Brick will always interpolate your step inputs as 1/256-step. If you use full-step mode with interpolation, each step will generate 256 1/256 steps. For maximum torque use full-step without interpolation. For maximum resolution use 1/256-step. Turn interpolation on to make the Stepper driving less noisy. If you often change the speed with high acceleration you should turn the interpolation off.

        public int getStackInputVoltage()
                                 throws TinkerforgeException
        Returns the stack input voltage. The stack input voltage is the voltage that is supplied via the stack, i.e. it is given by a Step-Down or Step-Up Power Supply.
        Throws:
        TinkerforgeException
      • getExternalInputVoltage

        public int getExternalInputVoltage()
                                    throws TinkerforgeException
        Returns the external input voltage. The external input voltage is given via the black power input connector on the Silent Stepper Brick. If there is an external input voltage and a stack input voltage, the motor will be driven by the external input voltage. If there is only a stack voltage present, the motor will be driven by this voltage. \warning This means, if you have a high stack voltage and a low external voltage, the motor will be driven with the low external voltage. If you then remove the external connection, it will immediately be driven by the high stack voltage

        TinkerforgeException
      • enable

        public void enable()
                    throws TinkerforgeException
        Enables the driver chip. The driver parameters can be configured (maximum velocity, acceleration, etc) before it is enabled.
        Throws:
        TinkerforgeException
      • disable

        public void disable()
                     throws TinkerforgeException
        Disables the driver chip. The configurations are kept (maximum velocity, acceleration, etc) but the motor is not driven until it is enabled again. \warning Disabling the driver chip while the motor is still turning can damage the driver chip. The motor should be stopped calling stop() function before disabling the motor power. The stop() function will **not** wait until the motor is actually stopped. You have to explicitly wait for the appropriate time after calling the stop() function before calling the disable() function.

                                   throws TinkerforgeException
        Sets the basic configuration parameters for the different modes (Stealth, Coolstep, Classic). * Standstill Current: This value can be used to lower the current during stand still. This might be reasonable to reduce the heating of the motor and the Brick. When the motor is in standstill the configured motor phase current will be driven until the configured Power Down Time is elapsed. After that the phase current will be reduced to the standstill current. The elapsed time for this reduction can be configured with the Standstill Delay Time. The maximum allowed value is the configured maximum motor current (see setMotorCurrent(int)). * Motor Run Current: The value sets the motor current when the motor is running. Use a value of at least one half of the global maximum motor current for a good microstep performance. The maximum allowed value is the current motor current. The API maps the entered value to 1/32 ... 32/32 of the maximum motor current. This value should be used to change the motor current during motor movement, whereas the global maximum motor current should not be changed while the motor is moving (see setMotorCurrent(int)). * Standstill Delay Time: Controls the duration for motor power down after a motion as soon as standstill is detected and the Power Down Time is expired. A high Standstill Delay Time results in a smooth transition that avoids motor jerk during power down. * Power Down Time: Sets the delay time after a stand still. * Stealth Threshold: Sets the upper threshold for Stealth mode. If the velocity of the motor goes above this value, Stealth mode is turned off. Otherwise it is turned on. In Stealth mode the torque declines with high speed. * Coolstep Threshold: Sets the lower threshold for Coolstep mode. The Coolstep Threshold needs to be above the Stealth Threshold. * Classic Threshold: Sets the lower threshold for classic mode. In classic mode the stepper becomes more noisy, but the torque is maximized. * High Velocity Chopper Mode: If High Velocity Chopper Mode is enabled, the stepper control is optimized to run the stepper motors at high velocities. If you want to use all three thresholds make sure that Stealth Threshold < Coolstep Threshold < Classic Threshold.

Spreadcycle is a chopper algorithm which actively controls the motor current flow. More information can be found in the TMC2130 datasheet on page 47 (7 spreadCycle and Classic Chopper). * Slow Decay Duration: Controls duration of off time setting of slow decay phase. 0 = driver disabled, all bridges off. Use 1 only with Comparator Blank time >= 2. * Enable Random Slow Decay: Set to false to fix chopper off time as set by Slow Decay Duration. If you set it to true, Decay Duration is randomly modulated. * Fast Decay Duration: Sets the fast decay duration. This parameters is only used if the Chopper Mode is set to Fast Decay. * Hysteresis Start Value: Sets the hysteresis start value. This parameter is only used if the Chopper Mode is set to Spread Cycle. * Hysteresis End Value: Sets the hysteresis end value. This parameter is only used if the Chopper Mode is set to Spread Cycle. * Sine Wave Offset: Sets the sine wave offset. This parameters is only used if the Chopper Mode is set to Fast Decay. 1/512 of the value becomes added to the absolute value of the sine wave. * Chopper Mode: 0 = Spread Cycle, 1 = Fast Decay. * Comparator Blank Time: Sets the blank time of the comparator. Available values are * 0 = 16 clocks, * 1 = 24 clocks, * 2 = 36 clocks and * 3 = 54 clocks. A value of 1 or 2 is recommended for most applications. * Fast Decay Without Comparator: If set to true the current comparator usage for termination of the fast decay cycle is disabled.

Sets the configuration relevant for Stealth mode. * Enable Stealth: If set to true the stealth mode is enabled, if set to false the stealth mode is disabled, even if the speed is below the threshold set in setBasicConfiguration(int, int, int, int, int, int, int, boolean). * Amplitude: If autoscale is disabled, the PWM amplitude is scaled by this value. If autoscale is enabled, this value defines the maximum PWM amplitude change per half wave. * Gradient: If autoscale is disabled, the PWM gradient is scaled by this value. If autoscale is enabled, this value defines the maximum PWM gradient. With autoscale a value above 64 is recommended, otherwise the regulation might not be able to measure the current. * Enable Autoscale: If set to true, automatic current control is used. Otherwise the user defined amplitude and gradient are used. * Force Symmetric: If true, A symmetric PWM cycle is enforced. Otherwise the PWM value may change within each PWM cycle. * Freewheel Mode: The freewheel mode defines the behavior in stand still if the Standstill Current (see setBasicConfiguration(int, int, int, int, int, int, int, boolean)) is set to 0.

        Note: If you don't know what any of this means you can very likely keep all of the values as default! Sets the configuration relevant for Coolstep. * Minimum Stallguard Value: If the Stallguard result falls below this value*32, the motor current is increased to reduce motor load angle. A value of 0 turns Coolstep off. * Maximum Stallguard Value: If the Stallguard result goes above (Min Stallguard Value + Max Stallguard Value + 1) * 32, the motor current is decreased to save energy. * Current Up Step Width: Sets the up step increment per Stallguard value. The value range is 0-3, corresponding to the increments 1, 2, 4 and 8. * Current Down Step Width: Sets the down step decrement per Stallguard value. The value range is 0-3, corresponding to the decrements 1, 2, 8 and 16. * Minimum Current: Sets the minimum current for Coolstep current control. You can choose between half and quarter of the run current. * Stallguard Threshold Value: Sets the level for stall output (see getDriverStatus()). A lower value gives a higher sensitivity. You have to find a suitable value for your motor by trial and error, 0 works for most motors. * Stallguard Mode: Set to 0 for standard resolution or 1 for filtered mode. In filtered mode the Stallguard signal will be updated every four full-steps.

        Returns the current driver status. * Open Load: Indicates if an open load is present on phase A, B or both. This could mean that there is a problem with the wiring of the motor. False detection can occur in fast motion as well as during stand still. * Short To Ground: Indicates if a short to ground is present on phase A, B or both. If this is detected the driver automatically becomes disabled and stays disabled until it is enabled again manually. * Over Temperature: The over temperature indicator switches to "Warning" if the driver IC warms up. The warning flag is expected during long duration stepper uses. If the temperature limit is reached the indicator switches to "Limit". In this case the driver becomes disabled until it cools down again. * Motor Stalled: Is true if a motor stall was detected. * Actual Motor Current: Indicates the actual current control scaling as used in Coolstep mode. It represents a multiplier of 1/32 to 32/32 of the ``Motor Run Current`` as set by setBasicConfiguration(int, int, int, int, int, int, int, boolean). Example: If a ``Motor Run Current`` of 1000mA was set and the returned value is 15, the ``Actual Motor Current`` is 16/32*1000mA = 500mA. * Stallguard Result: Indicates the load of the motor. A lower value signals a higher load. Per trial and error you can find out which value corresponds to a suitable torque for the velocity used in your application. After that you can use this threshold value to find out if a motor stall becomes probable and react on it (e.g. decrease velocity). During stand still this value can not be used for stall detection, it shows the chopper on-time for motor coil A. * Stealth Voltage Amplitude: Shows the actual PWM scaling. In Stealth mode it can be used to detect motor load and stall if autoscale is enabled (see setStealthConfiguration(boolean, short, short, boolean, boolean, short)).

                                     throws TinkerforgeException
        The SPITF protocol can be used with a dynamic baudrate. If the dynamic baudrate is enabled, the Brick will try to adapt the baudrate for the communication between Bricks and Bricklets according to the amount of data that is transferred. The baudrate will be increased exponentially if lots of data is sent/received and decreased linearly if little data is sent/received. This lowers the baudrate in applications where little data is transferred (e.g. a weather station) and increases the robustness. If there is lots of data to transfer (e.g. Thermal Imaging Bricklet) it automatically increases the baudrate as needed. In cases where some data has to transferred as fast as possible every few seconds (e.g. RS485 Bricklet with a high baudrate but small payload) you may want to turn the dynamic baudrate off to get the highest possible performance. The maximum value of the baudrate can be set per port with the function setSPITFPBaudrate(char, long). If the dynamic baudrate is disabled, the baudrate as set by setSPITFPBaudrate(char, long) will be used statically. .. versionadded:: 2.0.4$nbsp;(Firmware)

        Sets the baudrate for a specific Bricklet port. If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference (see getSPITFPErrorCount(char)) you can decrease the baudrate. If the dynamic baudrate feature is enabled, the baudrate set by this function corresponds to the maximum baudrate (see setSPITFPBaudrateConfig(boolean, long)). Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.
