Smart HMI System with Voice & Display Interfaces

Human machine interfaces (HMIs) are essential components that connect people to machines, systems, or devices, enabling control over various functions and access to data. As technology advances, HMIs need to incorporate features like connectivity (via Wi-Fi, Bluetooth, etc.) and LCD screens to support more complex interactions and commands between humans and machines.

This high-performance smart HMI system utilizes a 32-bit MCU, supporting graphical user interface (GUI) creation with an LCD, voice input/output, and IoT connectivity through Wi-Fi, Bluetooth^® Low Energy (LE), Ethernet, and more.
