Introduction
CircuitPython is a popular programming language used for developing microcontroller-based projects. It is a subset of the Python programming language, designed specifically for microcontrollers. CircuitPython WebSocket is a protocol that allows for real-time communication between a client and a server. The protocol is built on top of the WebSocket API, which is a standardized protocol for two-way communication between a client and a server over a single, long-lived connection.
What is a WebSocket?
A WebSocket is a protocol that enables two-way communication between a client and a server. Unlike HTTP, which is a request-response protocol, WebSocket enables real-time, bi-directional communication. This means that data can be sent and received by both the client and the server at any time, without the need for a request from either side.
WebSocket was first introduced in 2008 and has since become a popular protocol for real-time web applications. It is supported by all major web browsers and can be used with a variety of programming languages.
What is CircuitPython?
CircuitPython is a programming language designed specifically for microcontrollers. It is based on the Python programming language and is designed to be easy to use and understand. CircuitPython is designed to make it easy for anyone to get started with microcontroller programming, regardless of their programming experience.
CircuitPython is used by hobbyists, educators, and professionals alike. It is supported by a variety of microcontrollers, including the popular Adafruit Circuit Playground Express and the Raspberry Pi Pico.
What is CircuitPython WebSocket?
CircuitPython WebSocket is a protocol that allows for real-time communication between a client and a server. The protocol is built on top of the WebSocket API, which is a standardized protocol for two-way communication between a client and a server over a single, long-lived connection.
CircuitPython WebSocket is designed specifically for use with CircuitPython microcontrollers. It provides a simple and easy-to-use interface for communicating with other devices over the internet.
How does CircuitPython WebSocket work?
CircuitPython WebSocket works by establishing a WebSocket connection between a client and a server. Once the connection is established, data can be sent and received between the two devices in real-time.
The client and server both use the WebSocket API to establish and manage the connection. The client sends a WebSocket handshake request to the server, and if the server accepts the request, a WebSocket connection is established.
Once the connection is established, data can be sent and received between the client and server using the WebSocket API. The data is sent in packets, which can be received and processed by the client or server in real-time.
Why use CircuitPython WebSocket?
CircuitPython WebSocket is a powerful protocol that enables real-time communication between devices. It is ideal for a variety of applications, including IoT devices, robotics, and more.
Some of the key benefits of using CircuitPython WebSocket include:
