FAQ
- What is MEMS Studio?
- MEMS Studio is a desktop software solution for a 360-degree MEMS sensor portfolio experience. It provides a versatile development environment for evaluating and programming all MEMS sensors, developing embedded AI features, evaluating embedded libraries, analyzing data, and designing no-code algorithms. MEMS Studio includes Unico-GUI, Unicleo-GUI, and AlgoBuilder.
- How do I update the firmware of STEVAL-MKI109D using MEMS Studio?
- To update the firmware, plug the STEVAL-MKI109D into the PC using a USB-C cable, launch MEMS Studio, press Connect after the serial port is selected, and follow the on-screen instructions for firmware upgrade.
