Dear sir thanks a lot for this lib it's amazing but i have a bug that i don't understand where it's comming from

i have declare

`#ifdef GNUC
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
#else
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
#endif

PUTCHAR_PROTOTYPE{
/*{
HAL_UART_Transmit(&huart1, (uint8_t )&ch, 1, HAL_MAX_DELAY); // Replace huart2 with your UART handle
return ch;
}/
if (HAL_UART_Transmit_IT(&huart1, (uint8_t *)&ch, 1) != HAL_OK)
{
Error_Handler();
}

while (HAL_UART_GetState(&huart1) != HAL_UART_STATE_READY)
{
}

return ch;
}

while (1)
{
HAL_Delay (1000);

  //uint8_t buffers[50];
/* USER CODE END WHILE */
  printf("exp: %f\n",GPS.nmea_latitude);// response ok print 
  printf("exp: %i\n",GPS.satelites);// return print 0
/* USER CODE BEGIN 3 */

/* USER CODE END 3 */
}
