ST-NUCLEO F411RE使用RW007事项

直接使用 stm32f411-st-nucleo BSP，根据 官方文档中的 rw007 SPI WiFi 模块使用教程配置后，编译下载后没能够正常运行。
在 stm32f4xx_hal_msp.c 文件里注意到SPI1的初始化函数中管脚配置与RW007的Arduino接口不一致，
```void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
{

GPIO_InitTypeDef GPIO_InitStruct = {0};
  if(hspi->Instance==SPI1)
  {
  /* USER CODE BEGIN SPI1_MspInit 0 */

/* USER CODE END SPI1_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_SPI1_CLK_ENABLE();
  
    __HAL_RCC_GPIOA_CLK_ENABLE();
    __HAL_RCC_GPIOB_CLK_ENABLE();
    /**SPI1 GPIO Configuration    
    PA5     ------> SPI1_SCK
    PB4     ------> SPI1_MISO
    PB5     ------> SPI1_MOSI 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_5;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

GPIO_InitStruct.Pin = GPIO_PIN_4|GPIO_PIN_5;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
    HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

/* USER CODE BEGIN SPI1_MspInit 1 */

/* USER CODE END SPI1_MspInit 1 */
  }

}```把引脚配置修改与Arduino接口一致后可以运行正常
```void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  if(hspi->Instance==SPI1)
  {
  /* USER CODE BEGIN SPI1_MspInit 0 */

/* USER CODE END SPI1_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_SPI1_CLK_ENABLE();
  
    __HAL_RCC_GPIOA_CLK_ENABLE();
    /**SPI1 GPIO Configuration    
    PA5     ------> SPI1_SCK
    PA6     ------> SPI1_MISO
    PA7     ------> SPI1_MOSI 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

/* USER CODE BEGIN SPI1_MspInit 1 */

/* USER CODE END SPI1_MspInit 1 */
  }

}```
