Configuration of the TMC2130 is done via SPI. A dedicated motion controller IC or the CPU sends step and direction signals to the TMC2130. The TMC2130 provides the related motor coil currents to operate the motor. In Standalone Mode, the TMC2130 can be configured using pins. In this mode of operation CPU interaction is not necessary. The third mode of operation is the SPI Driver Mode, which is used in combination with TRINAMICs TMC4361 motion controller chip. This mode of operation offers several possibilities for sophisticated applications. OPERATION MODE 1: Step/Direction Driver Mode An external motion controller is used or a central CPU generates step and direction signals. The motion controller (e.g. TMC429) controls the motor position by sending pulses on the STEP signal while indicating the direction on the DIR signal. The TMC2130 provides a microstep counter and a sine table to convert these signals into the coil currents which control the position of the motor. The TMC2130 automatically takes care of intelligent current and mode control and delivers feedback on the state of the motor. The microPlyer automatically smoothens motion. To optimize power consumption and heat dissipation, software may also adjust coolStep and stallGuard2 parameters in real-time, for example to implement different tradeoffs between speed and power consumption.
