怎样去配置基于RT-Thread STM32L475的TF卡呢

一、硬件

一、硬件

1.潘多拉stm32L475开发板/W25Q128/TF卡64M

二、软件环境

1.Win10/rt-thread studio2.2.4/rt-thread 4.1.0

三、参考潘多拉开发板SDK及实例程序

四、操作内容

1.先配置rt-thread 4.1.0最基本功能，通过串口打印信息

2.rt-thread setting->spi/dfs/fatfs

3.tf卡驱动

#include <rtthread.h>

#include <rtdevice.h>

#include "drv_spi.h"

#include "spi_msd.h"

#ifdef BSP_USING_TF_CARD

void HAL_SPI_MspInit(SPI_HandleTypeDef *spiHandle)

{

GPIO_InitTypeDef GPIO_InitStruct;

RT_ASSERT(spiHandle != RT_NULL);

#ifdef BSP_USING_SPI1

if (spiHandle->Instance == SPI1)

{

    /* SPI1 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);

}

#endif

}

void HAL_SPI_MspDeInit(SPI_HandleTypeDef *spiHandle)

{

RT_ASSERT(spiHandle != RT_NULL);

#ifdef BSP_USING_SPI1

if (spiHandle->Instance == SPI1)

{

    /* Peripheral clock disable */

    __HAL_RCC_SPI1_CLK_DISABLE();

    /**SPI1 GPIO Configuration

    PA5     ------> SPI1_SCK

    PA6     ------> SPI1_MISO

    PA7     ------> SPI1_MOSI

    */

    HAL_GPIO_DeInit(GPIOA, GPIO_PIN_5 | GPIO_PIN_6 | GPIO_PIN_7);

}

#endif

}

static int rt_hw_spi1_tfcard(void)

{

__HAL_RCC_GPIOC_CLK_ENABLE();

rt_hw_spi_device_attach("spi1", "spi10", GPIOC, GPIO_PIN_3);

return msd_init("sd0", "spi10");

}

INIT_COMPONENT_EXPORT(rt_hw_spi1_tfcard);

4.修改board.h文件，打开spi1定义宏

/ -------------------------- SPI CONFIG BEGIN -------------------------- /

/** 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

*/

#define BSP_USING_SPI1

/ #define BSP_USING_SPI2 /

/ #define BSP_USING_SPI3 /

#define BSP_USING_TF_CARD // 添加

5.main.c文件挂载文件系统

int main(void)

{

int count = 1;

if (dfs_mount("sd0", "/", "elm", 0, 0) == 0)

{

    LOG_I("Filesystem initialized!");

} else

{

    LOG_E("Failed to initialize filesystem!");

}

while (count++)

{

// LOG_D("Hello RT-Thread!");

rt_thread_mdelay(1000);

}

return RT_EOK;

}

6.编译程序

7.下载程序

8.NM25Q128 flash驱动

board.h中打开宏定义

#define BSP_USING_QSPI

#define BSP_USING_ON_CHIP_FLASH

添加

#define BSP_QSPI_USING_SOFTCS

#define BSP_USING_QSPI_FLASH

fal组件使能

添加drv_qspi_flash.c

#include <board.h>

#include <drv_qspi.h>

#include <rtdevice.h>

#include <rthw.h>

#include <finsh.h>

#ifdef BSP_USING_QSPI_FLASH

#include "spi_flash.h"

#include "spi_flash_sfud.h"

#define QSPI10_CS GET_PIN(E, 11)

void HAL_QSPI_MspInit(QSPI_HandleTypeDef *hqspi)

{

GPIO_InitTypeDef GPIO_InitStruct;

/* QSPI clock enable */

__HAL_RCC_QSPI_CLK_ENABLE();

__HAL_RCC_GPIOE_CLK_ENABLE();

/* QSPI1 GPIO Configuration

PE10     ------> QSPI_BK1_CLK

PE11     ------> QSPI_SOFT_CS

PE12     ------> QSPI_BK1_IO0

PE13     ------> QSPI_BK1_IO1

PE14     ------> QSPI_BK1_IO2

PE15     ------> QSPI_BK1_IO3

*/

GPIO_InitStruct.Pin = GPIO_PIN_10 | GPIO_PIN_12 | GPIO_PIN_13 | GPIO_PIN_14 | GPIO_PIN_15;

GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;

GPIO_InitStruct.Pull = GPIO_NOPULL;

GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;

GPIO_InitStruct.Alternate = GPIO_AF10_QUADSPI;

HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);

}
