A system using a TMC429 motion controller together with a TMC262 stepper motor driver requires a MCU to initialize the TMC429 and the TMC262 driver via SPI. Optionally the MCU may read back status information via the same channel. After initialization the control may be done with the internal sequencer via SPI or STEP/DIR signals. To offload the MCU from ramp calculations the dedicated ramp controller TMC429 is utilized. The TMC262 drives a MOSFET power stage that consists of two full bridges using P- and N-MOSFET pairs.
