Main Program

main.cpp serves as the entry point of the entire project, responsible for initializing various components and managing the application's execution. It mainly handles the following functionalities:

• Initializing all devices and services.
• Handling events from devices and services.
• Managing the lifecycle of devices and services.

Cognex

The Cognex section contains the code for interacting with Cognex vision systems. The specific implementation resides in Cognex.h and Cognex.cpp. This component offers the following functionalities:

• Connecting and disconnecting from the Cognex vision system.
• Sending and receiving data.
• Handling events from the Cognex vision system.

HTTP API Manager

The HttpApiManager section's code is responsible for handling interactions with HTTP APIs. This component provides the following functionalities:

• Sending requests to the HTTP API.
• Receiving and handling responses from the HTTP API.
• Managing the state of the HTTP API.

Domino

The Domino section's code includes the functionalities for interacting with Domino printers. The specific implementation can be found in Domino.h and Domino.cpp. This component provides the following functionalities:

• Connecting and disconnecting from the Domino printer.
• Sending and receiving data.
• Handling events from the Domino printer.

Tools

The code in the Tools directory contains several utility functions and classes, offering the following functionalities:

• TaskQueue: A thread-safe task queue, allowing safe addition and removal of tasks across multiple threads.
• LockFreeQueue: A lock-free queue using atomic operations to ensure thread safety in multi-threaded environments.
• ModbusClient: A Modbus client for communicating with devices supporting the Modbus protocol.
• TCPClient: A TCP client for TCP communication.
• Other utilities: Including tools for logging, time management, string processing, and more.

Application Framework
