RT_DEVICE_FLAG_RDWR| RT_DEVICE_FLAG_INT_RX,//dev->flag (not dev->open_flag)uart); 显然,函数 stm32_hw_usart_init(),顾名思义,是用于初始化USART硬件的函数,因此这个函数一定会在USART使用之前被调用。搜索工程发现,这个函数是在board.c中rt_hw_board_init函数中被调用,而rt_hw_board_init函数又...
rt_hw_usart_init：这个函数将进行uart初始化.此函数本身对具体的芯片提供的串口参数（USART_InitTypeDef）进行配置，然后调用一个rt_hw_serial_register函数进行注册工作。rt_hw_serial_register：这个函数将会对传进来的rt_device_t对象进行初始化，初始化主要是对串口的一下统一接口进行指定。如下所示：代码: 全选 ...
