RT-Thread配置

SPI配置 在board.h文件中，参考SPI配置说明依次配置SPI参数

/ -------------------------- SPI CONFIG BEGIN --------------------------/ /** if you want to use spi bus you canuse 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

#define HAL_SPI_MODULE_ENABLED

在drv_spi.c文件的spi_config数组中用到了SPI6_BUS_CONFIG，默认工程是没有的，需要自己添加，可以参考已有的SPI配置

在spi_config.h文件尾部添加SPI6_BUS_CONFIG

#ifdef BSP_USING_SPI6 #ifndef SPI6_BUS_CONFIG #define SPI6_BUS_CONFIG { .Instance = SPI6, .bus_name = "spi6", } #endif /* SPI6_BUS_CONFIG / #endif /BSP_USING_SPI6 / //#ifdef BSP_SPI6_TX_USING_DMA//#ifndef SPI6_TX_DMA_CONFIG //#define SPI6_TX_DMA_CONFIG // { // .dma_rcc = SPI6_TX_DMA_RCC, // .Instance = SPI6_TX_DMA_INSTANCE, // .channel = SPI6_TX_DMA_CHANNEL, // .dma_irq = SPI6_TX_DMA_IRQ, // } //#endif /SPI6_TX_DMA_CONFIG / //#endif /BSP_SPI6_TX_USING_DMA / // //#ifdef BSP_SPI6_RX_USING_DMA //#ifndef SPI6_RX_DMA_CONFIG //#define SPI6_RX_DMA_CONFIG // { // .dma_rcc = SPI6_RX_DMA_RCC, // .Instance = SPI6_RX_DMA_INSTANCE, // .channel = SPI6_RX_DMA_CHANNEL, // .dma_irq = SPI6_RX_DMA_IRQ, // } //#endif /SPI6_RX_DMA_CONFIG / //#endif /BSP_SPI6_RX_USING_DMA */ 在dfs_fs.c文件中，添加文件系统默认装载表：

const struct dfs_mount_tbl mount_table[] = { {"sd0", "/", "elm", 0, 0}, {0} };

在driver目录下添加drv_spi_tfcard.c文件

测试

至此完成基于SPI的SD驱动框架。

遗留问题 添加SD后，MPU配置会影响以太网ping的效果，使用下面配置SD卡、以太网均正常
