ATEQ G520 Communication DLL Library

This project provides a DLL library for communicating with the ATEQ G520 air/air leak detector via a serial port (RS-232). The library allows you to send commands to the device and read data from it, enabling seamless integration with your applications for leak detection and testing.

Protocol description

Features

• Easily open and close communication with the ATEQ G520 device.

• Send specific commands to the device, such as starting, stopping, resetting, and setting programs.

• Read data from the device, including status information and test results.

• Robust error handling to ensure reliable communication with the device.

Installation

• Clone or download the repository.

• Build the project to generate the DLL.

• Include the DLL in your project.

• Link the DLL in your application and use the provided functions to interact with the ATEQ G520 device.

Available Functions

AteqOpen(LPCTSTR comPort): Opens the serial port and initializes communication with the ATEQ G520 device.

Returns a unique ID for the opened connection, or a negative value on error.

AteqGetStatus(int ateqId, BYTE* buffer, int bufferSize): Retrieves the status of the device.

Returns the number of bytes read, or a negative value on error.

AteqSetProgram(int ateqId, BYTE programNumber, BYTE* buffer, int bufferSize): Sets the program on the device.

Returns the number of bytes read, or a negative value on error.

AteqStart(int ateqId, BYTE* buffer, int bufferSize): Starts the leak detection process.

Returns the number of bytes read, or a negative value on error.

AteqStop(int ateqId, BYTE* buffer, int bufferSize): Stops the leak detection process.

Returns the number of bytes read, or a negative value on error.

AteqReset(int ateqId, BYTE* buffer, int bufferSize): Resets the device.

Returns the number of bytes read, or a negative value on error.

AteqClose(int ateqId): Closes the COM port and releases resources.

Returns 1 on success, 0 on failure.

Error Codes

-1: Invalid device ID or device not found.

-2: General exception or error.

-3: Failed to write to the device.

-4: Failed to wait for an event.

-5: Failed to send a break signal.

-6: Failed to read from the device.
