Programming STM32F4DISC Board With ArduinoIDE (STM32Duino)

Reference : https://github.com/stm32duino/Arduino_Core_STM32

Accelerating your stm32 projects with stm32duino.

1. PC / Laptop with ArduinoIDE software
2. STM32F4DISC Board
3. Downloader Cable (Mini USB)
4. AWG30 Cable 20 cm (Optional for Serial Debugging)

1. Click File -> preference
2. In the "Additional Board Manager URLs" add this link: https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json 
3. click OK

1. Go to Tools -> Boards -> Boards Manager
2. Search for "stm32duino"
3. Click Install on the "STM32 Based MCU Boards"
4. Wait for the instalation process to complete

We will install STM32CubeProg to solve driver problems.

1. First, go to this link
2. Download STM32CubeProg. You will need to log in, or you can download it as a guest. The download link will be sent to your email. Make sure you use the same browser to open the link as the one you used to request it previously.
3. Extract the file and install STM32CubeProg by following the steps until the instalation is complete

1. Write the code below
2. Click Tools -> Boards -> STM32 Based MCU Boards -> Generic STM32F4 Boards
3. Make sure the downloader cable is plugged in
4. Click Upload or press CTRL+U on keyboard

const int led_pin[4] = {PD12, PD13, PD14, PD15};

void setup() {
 // put your setup code here, to run once:
 for(int i = 0; i < 4; i++)
 {
  pinMode(led_pin[i], OUTPUT);
 }
}

void loop() {
 // put your main code here, to run repeatedly:
 for(int i = 0; i < 4; i++)
 {
  digitalWrite(led_pin[i], HIGH);
  delay(100);
  digitalWrite(led_pin[i], LOW);
  delay(100);
 } 
}

1. Configure the hardware, Use flying wires to connect (ST-LINK VCP pin 12 and 13) to (STM32F407 USART2 pin PA2 and PA3) as shown in the figure
2. Click Tools -> Boards -> STM32 Based MCU Boards -> Generic STM32F4 Boards
3. Write the code below
4. Make sure the downloader cable is plugged in
5. Click Upload or press CTRL+U on keyboard
6. Click Serial Monitor in the top right corner or press CTRL+M on keyboard
7. Change the baudrate to 115200 to match what we programmed

#include <HardwareSerial.h>

HardwareSerial Serial2(PA3,PA2);

void setup() {
  // put your setup code here, to run once:
  Serial2.begin(115200); // Initialization

}

void loop() {
  // put your main code here, to run repeatedly:
  Serial2.println("Hello World!");
  delay(1000);
    
}
