Smart HMI System with Voice & Display Interfaces

Overview

Description

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.

System Benefits​:

  • The RX72N Envision Kit includes a variety of I/O peripherals, facilitating the development of solutions for diverse applications. The pre-installed demo and emulator circuit enable immediate development for quicker system testing and evaluation.
  • Rich interfaces support the expansion of system functions and accommodate various development scenarios for a flexible and versatile design.
  • An audio codec IC with a stereo MEMS microphone supports voice input and output.
  • Sample code for voice recognition, GUI, LCD, and AWS Cloud and FreeRTOS connectivity facilitates fast system development.
