RTT-Studio使用CubeMx开发串口报错

RTT-Studio使用CubeMx开发串口报错

一、问题描述

在RT-Thread Studio进行开发，建立了基于芯片（STM32F407ZET6）的工程，打开STM32CubeMX进行基本外设配置，配置完成生成代码，回到Studio IDE进行编译时一堆报错，具体如下：

../drivers/drv_usart.c:94:5: error: unknown type name 'UART_HandleTypeDef'
     UART_HandleTypeDef handle;
     ^
../drivers/drv_usart.c: In function 'stm32_configure':
../drivers/drv_usart.c:413:17: error: request for member 'Instance' in something not a structure or union
     uart->handle.Instance          = uart->config->Instance;
                 ^
../drivers/drv_usart.c:414:17: error: request for member 'Init' in something not a structure or union
     uart->handle.Init.BaudRate     = cfg->baud_rate;
                 ^
../drivers/drv_usart.c:415:17: error: request for member 'Init' in something not a structure or union
     uart->handle.Init.HwFlowCtl    = UART_HWCONTROL_NONE;
                 ^
../drivers/drv_usart.c:415:38: error: 'UART_HWCONTROL_NONE' undeclared (first use in this function)
     uart->handle.Init.HwFlowCtl    = UART_HWCONTROL_NONE;
                                      ^
../drivers/drv_usart.c:415:38: note: each undeclared identifier is reported only once for each function it appears in
../drivers/drv_usart.c:416:17: error: request for member 'Init' in something not a structure or union
     uart->handle.Init.Mode         = UART_MODE_TX_RX;

二、原因分析

以上报错都是与串口有关，而移植RT-Thread时使用了串口1作为终端串口，开始时工程默认配置好，但重新配置完Cube后，串口1确没有配置，所以出现报错！

三、解决方法

在STM32CubeMX里面配置一下我们用到的终端串口，例如我这里使用的是串口1，在cubeMX里面点击配置就行
