32F746G-DISCOVERY

The STM32F7 discovery kit allows users to develop and share applications with the STM32F7 Series microcontollers based on ARM® Cortex®-M7 core.

Install software

Step 1 build myST account

Step 2 download STM32CubeF7

Step 3 download and install STM32CubeProgrammer

Step 4 download and install STM32CubeMX

Step 5 install MDK-ARM


New Project

Open STM32CubeMX and select Start My project from STBoard “ACCESS TO BOARD SELECTOR”

Search “32F746” and select “STM32F746G-Disco”


Set Port (example is PI1 set GPIO_Output)


Set Project Name and Generate Code


Basic Example1


After launching MDK , then find command and edit main.c

  /* USER CODE BEGIN 3 */
    HAL_GPIO_TogglePin(GPIOI, GPIO_PIN_1);
    HAL_Delay(500);
}
  /* USER CODE END 3 */


Compile code and test on STM32


Press the Reset button (black button) and LD1 will flicker each 500ms


Basic Example2


Set Port (PI1 set GPIO_Output and PI11 set interrupts (GPIO_EXTI11))


Set Project Name and Generate Code


After launching MDK , then find command and edit main.c

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
    HAL_GPIO_TogglePin(GPIOI, GPIO_PIN_1);
}
/* USER CODE END 4 */


Compile code and test on STM32 and press black button then you can flicker LD1 by pressing blue button


Basic Example3


Set Port (PI1 set GPIO_Output and launch USART1)


Set Project Name and Generate Code


After launching MDK , then find command and edit main.c

    HAL_Delay(500);
}

  return ch;
}
/* USER CODE END 4 */


Compile code and test on STM32 and open TeraTerm


Show example2 on TeraTerm

Compile code and test on STM32 and open debug mode


Open TeraTerm


Input on Terminal and show on Watch 1


After ten inputs on Terminal


Basic Example5


Set Port (PI1 set GPIO_Output and launch USART1)
