HAL库记录-SDIO外设SD卡
正点原子--阿波罗开发板STM32F429IGT6
有个注意的地方: HAL_SD_Init 函数调用 HAL_SD_InitCard 函数有调用到
HAL_Delay(2); ,芯片滴答定时需要启动
1.STM32CubeMX配置
2.生成的代码

}注意:不要直接配置成4线模式, 要先配置成1位模式后,等初始化化完 HAL_SD_Init(&hsd) != HAL_OK
再手动配置为 4线模式, HAL_SD_ConfigWideBusOperation(&hsd, SDIO_BUS_WIDE_4B)
3.代码改进(判断是否有TF卡)
无卡初始化是无效的,需要等待卡插入,再次初始化成功后,才可以继续操作SDIO外设
/**
* @brief :函数作用 : 检测SDIO是否初始成功(也可以判断是否有卡插入)
* @param :函数入口 : 无
* @retval:函数返回 : 0:正常 1: HAL_SD_Init()初始化不过 2:HAL_SD_ConfigWideBusOperation()初始化不过
