What is the ESP32 CYD MCP Server?

This is a remote control server designed specifically for the ESP32 - 2432S028R development board. It uses WebSocket communication and the MCP protocol, allowing you to remotely control the display, touch functions, GPIO interfaces, and various sensors of the development board over the network.

How to use the ESP32 CYD MCP Server?

1. Flash the firmware to the development board. 2. Connect to the WiFi network of the development board. 3. Send control instructions in JSON format through a WebSocket client. 4. Receive responses and event notifications from the development board.

Application scenarios

Scenarios that require remote control of displays and sensors, such as IoT device prototype development, smart home control panels, educational demonstration tools, and industrial equipment monitoring interfaces.

Main features

Display control
Supports more than 20 display operations such as drawing text, graphics, and controlling the backlight.
Touch function
Provides more than 10 touch - related functions such as getting the touch state, calibrating the touch screen, and simulating touch events.
GPIO control
Includes 15 GPIO operations such as digital/analog input/output, PWM control, and interrupt handling.
Sensor monitoring
Reads sensor data such as temperature, light, and Hall effect, and supports calibration and batch reading.
Network tools
Provides 15 network functions such as WiFi connection management, HTTP requests, and NTP time synchronization.
File management
Supports more than 15 file system functions such as file reading and writing, and directory operations for SPIFFS and SD cards.
Advantages
Rich functions covering display, touch, GPIO, sensors, etc.
Based on the standard WebSocket protocol, compatible with various clients.
Real - time two - way communication, supporting event notifications.
Modular design, easy to expand new functions.
Limitations
Only supports the ESP32 - 2432S028R development board.
Requires a network connection to use.
Some advanced functions require additional hardware support.

How to use

Install the development environment
Install the PlatformIO or Arduino IDE development environment.
Get the project code
Clone the GitHub repository to your local machine.
Compile and upload the firmware
Use PlatformIO to compile and upload to the development board.
Connect to the development board
Connect to the development board via WiFi and get the IP address.
Send control instructions
Use a WebSocket client to connect to the server and send instructions in JSON format.

Usage examples

Display a welcome message
Display a welcome text in the center of the screen.
Create a temperature monitoring interface
Periodically read the temperature sensor and display the data on the screen.
