RISC-V industrial handheld controller with display, keypad and RS485

Integrated HMI

The controller acts as a compact HMI (Human Machine Interface) for interaction between the operator and the control system.

The combination of display and keypad allows operating information to be shown and commands to be executed directly from the terminal, with no need for touchscreens or additional computer systems.

This architecture is especially well suited to machinery, positioning systems and equipment installed in industrial or outdoor environments.

Graphic display

The unit features a graphic display that presents relevant application information clearly.

The display can show operating states, parameters, positions, process values, configuration menus, diagnostic messages and alarm conditions.

Local processing updates the information received over RS485 and gives the operator an immediate view of the system status.

Membrane keypad

The membrane keypad provides a robust physical interface for controlling the equipment.

The keys can be assigned to navigation, selection, motion activation, speed changes, operation confirmation or specific functions.

Compared with a touch-only interface, a physical keypad makes the terminal easier to use in applications that require a direct, clearly identifiable response from the operator.

RISC-V architecture

The system is based on a RISC-V architecture that manages the graphical interface, keypad, communications and operating logic of the terminal.

Local processing interprets user actions, updates the display and handles data exchange with the main controller of the installation.

This architecture provides a flexible embedded platform for developing user interfaces tailored to different applications.

FreeRTOS operating system

The firmware uses FreeRTOS as its real-time operating system.

The application can be structured as independent tasks for display management, keypad scanning, RS485 communications, diagnostics and operational monitoring.

This architecture supports deterministic behaviour and a fast response to operator actions.

RS485 communications

Communication between the controller and the main system is via RS485, an interface particularly well suited to industrial applications.

RS485 provides robust communications over longer distances than typical local electronic interfaces and offers good immunity to electrical interference.

Through this link, the terminal can receive status information and transmit the commands entered by the operator.

The integrated cable provides a direct connection between the controller and the controlled equipment, simplifying installation.

Environmental protection

The terminal is designed for applications where demanding environmental conditions may be present.

A sealed enclosure and membrane keypad make it possible to achieve an interface rated above IP55, suitable for environments with dust, humidity or exposure to water.

This allows the controller to be used both in industrial installations and outdoor applications, always in accordance with the specific certification conditions of the product.
