Project Title :Creation of a graphical interface

HMI (human machine interface) creation for controlling a train's onboard video transmission system using QT-Creator /STM32/I2C/UART/C/C++/STM32.

Description:

This project demonstrates how to interface an STM32 microcontroller with an OV7670 camera module using the I2C protocol to capture data. The captured data is then transmitted to a computer via UART. On the computer side, the data is read using QT Creator's QSerialPort module and displayed as an image using QLabel in a C++ application.

Features:

• Interface OV7670 camera with STM32 using I2C protocol
• Transmit captured data to a computer via UART
• Read and process the transmitted data using QT Creator's QSerialPort
• Display the processed data as an image using QLabel in a C++ application

Hardware Requirements:

• STM32 board (STM32F030 NUCLEO)
• OV7670 Camera
• UART converter(i used UART2 in this project because it is linked with ST link)

Software Requirements:

• STM32cudeIDE
• QT_Creator version 5.15.2
• PuTTY

Setup Instructions:

1. STM32 and OV7670 Setup:
• Connect the OV7670 camera to the STM32 microcontroller using I2C.
• configure the I2C ssettings in STM32cudeIDE
• Generate and compile the code using the STM32cubeIDE
2. UART Communication:
• Configure the UART settings in STM32CubeIDE.
3. QT Creator Setup:
• Install QT Creator and set up a new project.
• Add the QTSerialPort module to the project.
• Implement the code to read data from the serial port and display it using QLabel.

Result:

NB:

there is a problem i encountered :The problem is that the UART protocol cannot transmit all of the image data because its maximum capacity is limited to transmitting character data.
