串口一个函数的改写，求各位大佬帮忙

void USART3_IRQHandler(void)
{
      u8 res;

      if(USART_GetITStatus(USART3, USART_IT_RXNE) != RESET)//接收到数据
      {

      res =USART_ReceiveData(USART3);
      if((USART3_RX_STA&(1<<15))==0)//接收完的一批数据，还没有处理，则不再接收其它数据
      {
            if(USART3_RX_STA<USART3_MAX_RECV_LEN)             //还可以接收数据
            {
                     TIM_SetCounter(TIM7,0);//计数器清空
                     if(USART3_RX_STA==0)
                              TIM_Cmd(TIM7, ENABLE);  //使能定时器7
                     USART3_RX_BUF[USART3_RX_STA++]=res;             //记录接收到的值
            }else
            {
                     USART3_RX_STA|=1<<15;                                     //强制标志接收完成
            }
      }
}
}

大佬们，这一句USART3_RX_BUF[USART3_RX_STA++]=res; 怎么用HAL库函数改写？？
