Control via the SPI Interface
The SPI data word sets the current and polarity for both coils. By applying consecutive values,
describing a sine and a cosine wave, the motor can be driven in microsteps. Every microstep is
initiated by its own telegram. Please refer to the description of the analog mode for details on the
waveforms required. The SPI interface timing is described in the timing section. We recommend the
TMC428 to automatically generate the required telegrams and motor ramps for up to three motors.
