STM32CubeMX，Nano3.1.3移植FinSH问题

按照文档中心提供的方法移植FinSH的时候，出现问题感觉移植了半个FinSH，输入的命令只能是单个的单个的，无法连成一条，具体现象如下图所示：![55555555555555.png](https://oss-club.rt-thread.org/uploads/20210116/6c3b1ba08e4cda60308ed374c1866fb5.png)

环境：使用的STM32CubeMX6.1.1，Nano版本3.1.3

串口1

添加函数：
void rt_hw_console_output(const char *str)
{
        rt_size_t i = 0, size = 0;
        char a = '\r';
        
        __HAL_UNLOCK(&huart1);
        
        size = rt_strlen(str);
        for (i = 0; i < size; i++)
        {
        if (*(str + i) == '\n')
        {
                HAL_UART_Transmit(&huart1, (uint8_t *)&a, 1, 1);
        }
                HAL_UART_Transmit(&huart1, (uint8_t *)(str + i), 1, 1);
        }
}

char rt_hw_console_getchar(void)
{
        int ch = -1;
        if (__HAL_UART_GET_FLAG(&huart1, UART_FLAG_RXNE) != RESET)
        {
                ch = huart1.Instance->DR & 0xff;
        }
        else
        {
                if(__HAL_UART_GET_FLAG(&huart1, UART_FLAG_ORE) != RESET)
                {
                        __HAL_UART_CLEAR_OREFLAG(&huart1);
                }
                rt_thread_mdelay(10);
        }
        return ch;
}
