4. Create a New Project: Launch STM32CubeIDE and create a new project, selecting the STM32F746VET6 as your target device. Configure your settings through STM32CubeMX.

Writing Your First Application

Once your development environment is set, you can start programming. Below is a simple example of initializing an LED on the STM32F746VET6:

        #include "stm32f7xx_hal.h"
        
        void SystemClock_Config(void);
        static void MX_GPIO_Init(void);

        int main(void)
        {
            HAL_Init();
            SystemClock_Config();
            MX_GPIO_Init();
            
            while (1)
            {
                HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_0);  // Toggle the LED pin
                HAL_Delay(500);  // Delay for 500ms
            }
        }

        static void MX_GPIO_Init(void)
        {
            __HAL_RCC_GPIOB_CLK_ENABLE();
            GPIO_InitTypeDef GPIO_InitStruct = {0};
            GPIO_InitStruct.Pin = GPIO_PIN_0;
            GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
            GPIO_InitStruct.Pull = GPIO_NOPULL;
            GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
            HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
        }
    

This code initializes GPIOB pin 0 as an output and toggles its state every 500 milliseconds, effectively blinking an LED.
