Unzip it into [Arduino]/hardware folder
Download the latest GNU ARM Embedded Toolchain:
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
(The one in Arduino dosen't support STM32F7).
Change compiler.path in platform.txt to point to that you downloaded.
# This HAL is in development.
# Currently only tested on "The Borg".
You will also need the latest Arduino 1.9.0-beta or newer.
This HAL is a modified version of Chris Barr's Picoprint STM32F4 HAL, so shouldn't be to hard to get it to work on a F4.

* \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().

* 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.

* \param blank_time Selects the comparator blank time. This time needs to safely cover the switching event and the duration of the ringing on the sense resistor.

The sum hysteresis_start + hysteresis_end must be <16. At a current setting CS of max. 30 (amplitude reduced to 240), the sum is not limited.

* to the motor.
* Each chopper cycle is comprised of an on-phase, a slow decay phase, a fast decay phase and a second slow decay phase.
* The slow decay phases limit the maximum chopper frequency and are important for low motor and driver power dissipation.
* The hysteresis start setting limits the chopper frequency by forcing the driver to introduce a minimum amount of
* current ripple into the motor coils. The motor inductivity determines the ability to follow a changing motor current.
