【RT-Thread Studio】W25Q128配置

配置步骤

/** if you want to use spi bus you can use the following instructions.** STEP 1, open spi driver framework support in the RT-Thread Settings file** STEP 2, define macro related to the spi bus*                 such as     #define BSP_USING_SPI1** STEP 3, copy your spi init function from stm32xxxx_hal_msp.c generated by stm32cubemx to the end of board.c file*                 such as     void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)** STEP 4, modify your stm32xxxx_hal_config.h file to support spi peripherals. define macro related to the peripherals*                 such as     #define HAL_SPI_MODULE_ENABLED*/

STEP 1

RT-Thread Settings打开SPI SFUD

STEP 2

drivers\board.h

#define BSP_USING_SPI1

STEP 3

代码参考连接bsp/stm32/stm32f407-atk-explorer/board/CubeMX_Config/Src/stm32f4xx_hal_msp.c
board.c

/**
* @brief SPI MSP Initialization
* This function configures the hardware resources used in this example
* @param hspi: SPI handle pointer
* @retval None
*/
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_GPIOB_CLK_ENABLE();/**SPI1 GPIO ConfigurationPB3     ------> SPI1_SCKPB4     ------> SPI1_MISOPB5     ------> SPI1_MOSI*/GPIO_InitStruct.Pin = GPIO_PIN_3|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);/* SPI1 interrupt Init */HAL_NVIC_SetPriority(SPI1_IRQn, 0, 0);HAL_NVIC_EnableIRQ(SPI1_IRQn);/* USER CODE BEGIN SPI1_MspInit 1 *//* USER CODE END SPI1_MspInit 1 */}else if(hspi->Instance==SPI2){/* USER CODE BEGIN SPI2_MspInit 0 *//* USER CODE END SPI2_MspInit 0 *//* Peripheral clock enable */__HAL_RCC_SPI2_CLK_ENABLE();__HAL_RCC_GPIOC_CLK_ENABLE();__HAL_RCC_GPIOB_CLK_ENABLE();/**SPI2 GPIO ConfigurationPC2     ------> SPI2_MISOPC3     ------> SPI2_MOSIPB13     ------> SPI2_SCK*/GPIO_InitStruct.Pin = GPIO_PIN_2|GPIO_PIN_3;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_SPI2;HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);GPIO_InitStruct.Pin = GPIO_PIN_13;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_SPI2;HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);/* USER CODE BEGIN SPI2_MspInit 1 *//* USER CODE END SPI2_MspInit 1 */}}

如果不加这段代码，rtthread将会使用库自带的弱定义函数:

__weak void HAL_SPI_MspInit(SPI_HandleTypeDef *hspi)`

STEP 4

drivers\stm32f4xx_hal_conf.h

#define HAL_SPI_MODULE_ENABLED
