About
-----
The TMC26X is a stepper motor controller for bipolar stepper motors. From the trinamic web site:
The TMC262 is the first energy efficient high current high precision microstepping driver
IC for bipolar stepper motors. The unique high resolution sensorless load detection stallGuard2™
is used to for the world’s first integrated load dependent current control feature called coolStep™.
The ability to read out the load and detect an overload makes the TMC262 an optimum choice for
drives where a high reliability is desired at a low cost. The new patented spreadCycle PWM mixed
decay chopper scheme ensures best zero crossing performance as well as high speed operation.
The TMC262 can be driven with Step & Direction signals as well as by serial SPI™ interface.
Using the microPlyer allows to operate the motor with highest 256 μStep smoothness reducing the
input frequency to 16 μSteps. A full set of protection and diagnostic features makes this device
very rugged. It directly drives external MOSFETs for currents of up to 6A. This way it reaches
highest energy efficiency and allows driving of a high motor current without cooling measures
even at high environment temperatures.
The unique features of the TMC26X are that everything can (and must) be controlled in software:
* the motor current
* microstepping
* stall protection
* current reduction according to load
* stallGuard2™ sensorless load detection
* coolStep™ load dependent current control
* spreadCycle hysteresis PWM chopper
* microPlyer 16-to-256 μStep multiplier
* full protection and diagnostics
This makes the TMC26X a bit harder to use than other stepper motors but much more versatile.
This library resolves all the complicated stuff so that you can use TMC26X straight away.
Furthermore, all the settings are implemented in high level interfaces so that configuring your
motor is a breeze.

* In a constant off time chopper scheme both coil choppers run freely, i.e. are not synchronized.

* In order to minimize the effect of a beat between both chopper frequencies, an internal random generator is provided.

* \class TMC26XStepper
* \brief Class representing a TMC26X stepper driver
*
* In order to use one fo those drivers in your Arduino code you have to create an object of that class:
* \code
* TMC26XStepper stepper = TMC26XStepper(200,1,2,3,500);
* \endcode
* see TMC26XStepper(int number_of_steps, int cs_pin, int dir_pin, int step_pin, unsigned int rms_current)
*
* Keep in mind that you need to start the driver with start() in order to get the TMC26X configured.
*
* The most important function is the move(). It checks if the motor has to do a step or not.
* It is important that you call move() as often as possible in your Arduino loop() routine. I suggest
* to use a very fast loop routine and always call it at the beginning or the end.
*
* In order to move you have to provide a movement speed with setSpeed(). The speed is a positive value setting
* the rotations per minute.
*
* To really move the motor you have to call step() to tell the driver to move the motor the given number
* of steps in the given direction. Positive values move the motor in one direction, negative values in the other direction.
*
* You can check with isMoving() if the mototr is still moving or stop it apruptely with stop().

* \param use_curreent_comparator Selects usage of the current comparator for termination of the fast decay cycle. If current comparator is enabled, it terminates the fast decay cycle in case the current reaches a higher negative value than the actual positive value. (0 disable, -1 enable).
*
* The classic constant off time chopper uses a fixed portion of fast decay following each on phase.
* While the duration of the on time is determined by the chopper comparator, the fast decay time needs
* to be set by the user in a way, that the current decay is enough for the driver to be able to follow
* the falling slope of the sine wave, and on the other hand it should not be too long, in order to minimize
* motor current ripple and power dissipation. This best can be tuned using an oscilloscope or
* trying out motor smoothness at different velocities. A good starting value is a fast decay time setting
* similar to the slow decay time setting.
* After tuning of the fast decay time, the offset should be determined, in order to have a smooth zero transition.
* This is necessary, because the fast decay phase leads to the absolute value of the motor current being lower
* than the target current (see figure 17). If the zero offset is too low, the motor stands still for a short
* moment during current zero crossing, if it is set too high, it makes a larger microstep.
* Typically, a positive offset setting is required for optimum operation.
