AT32F423-RTOS 建立过程（三） [SES&rtthread3.1.5]_at32f423gpio

要想使用shell，必须是要使用uart1，对于我的这个板子。

注意这个不要勾！！！

加塞一个关于main.c文件的问题。（或者不需要它去修改的文件）

因为每次使用WorkBench生成新的文件的话会覆盖自己的源码文件，所以我建议把main.c文件不要用它自己生成的。

好，继续。。。

//在board.c文件最后粘贴以下代码
 
#ifdef RT_USING_CONSOLE
 
static int uart_init(void)
{
    // #error "TODO 2: Enable the hardware uart and config baudrate."
    return 0;
}
INIT_BOARD_EXPORT(uart_init);
 
void rt_hw_console_output(const char *str)
{
    // #error "TODO 3: Output the string 'str' through the uart."
    rt_enter_critical();
 
    /*进入临界区*/
    while (*str != '\0')
    {
        if (*str == '\n')
        {
            usart_data_transmit(USART1, '\r');
            while (usart_flag_get(USART1, USART_TDC_FLAG) == RESET)
                ;
        }
        usart_data_transmit(USART1, *str++);
        while (usart_flag_get(USART1, USART_TDC_FLAG) == RESET)
            ;
    }
 
    /* 退出临界区*/
    rt_exit_critical();
}
 
#endif

F7:构建 F8：下载。。。。

信息出来了。

扩展：

上一篇文章，我闪灯了，我这次要看一下延时时间是不是500ms。

这次实现了shell的显示，那么rtthread还有个比较不错的功能就是finsh，下一篇，我介绍以下RT_DEBUG和finsh的移植。
