LED Blink

Solving Approach

How do you plan to solve it?

 To have current as 10mA. I use (5V - 1.8V LED voltage drop) / 10mA = 320 Ohm resistor
 

Code

/*Paste your code here*/
//STM32F103C8T6
int main(void)
{

  /* USER CODE BEGIN 1 */

  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  /* USER CODE BEGIN 2 */

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
	  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_11, GPIO_PIN_SET);
	  HAL_Delay(400);
	  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_11, GPIO_PIN_RESET);
	  HAL_Delay(800);
  }
  /* USER CODE END 3 */
}
//Arduino Uno
void setup() {
  // put your setup code here, to run once:
  pinMode(7,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(7,LOW);
  delay(400);
  digitalWrite(7,HIGH);
  delay(800);
}
