TMC428-I

The TMC428 is a low-power, low-performance, high-performance three-axis step-control chip that integrates a pulse generator and waveform generator. Efficient current regulation. The TMC428 can be directly connected to an SPI driver or a Step/Dir driver. Another SPI is connected to the main controller. The microcontroller performs a higher level of control work, such as sending a command to drive the motor to a certain position, etc. The slope of the waveform can be automatically calculated based on the speed and acceleration parameters TMC428.
