#include "main.h"

int main(void)
{
  /* Reset of all peripherals, Initializes the Systick */
  HAL_Init();
  
  /* LED initialization */
  hled.Instance = LED;
  hled.Init.ComNum = 4 - 1;               /* Enable 4 COM ports */
  hled.Init.ComDrive = LED_COMDRIVE_LOW;  /* LED non-COM output */
  hled.Init.Prescaler = 10 - 1;           /* Fpclk/(PR+1) */
  hled.Init.LightTime = 0xF0;             /* Time each LED is illuminated */
  hled.Init.DeadTime = 0x10;              /* Interval time between two LED switches, must not be zero */
  HAL_LED_Init(&hled);

  /* Infinite loop */
  while (1)
  {
    dispNum++;
    if (dispNum == 10)
    {
      dispNum = 0;
    }
    HAL_Delay(1000);
  }
}
