@cutos/devices

Introduction

CUTOS Devices API is a JavaScript library that provides a unified interface for accessing and controlling hardware devices. Developers can use this interface to send and receive data, configure device parameters, and handle device events.

Devices and drivers communicate for data transmission, command reception, and status updates. Heartbeat monitoring is implemented for drivers to ensure continuous communication.
