MEMS-based Motor Control
This application provides an intuitive and natural way for controlling a stepper motor through an accelerometer. It makes use of the STMicroelectronics X-NUCLEO-IKS01A2 MEMS Inertial and Environmental Sensors Expansion Board to get accelerometer values and the X-NUCLEO-IHM01A1 Stepper Motor Control Expansion Board to directly control a stepper motor with:
- speed proportional to the angle measured by the MEMS board;
- direction driven by the direction of rotation captured by the MEMS board.
