编程状态(Programming State) 断开连接状态(Disconnect State) 37.4.2. 卡识别模式 在卡识别模式下,主机会复位所有处于“卡识别模式”的SD卡,确认其工作电压范围,识别SD卡类型,并且获取SD卡的相对地址(卡相对地址较短,便于寻址)。在卡识别过程中,要求SD卡工作在识别时钟频率FOD的状态下。卡识别模式下SD卡状态转换如...

The HAL_DeInit()function restores the peripheral default state, frees the low-level resources and removes any direct dependency with the hardware. The IO operation functions perform a row access to the peripheral payload data in write and read modes. The control functions are used to change ...
of examples. The HAL driver layer provides a simple, generic multi-instance set of APIs (application programming interfaces) to interact with the upper layer (application, libraries and stacks). The HAL driver APIs are split into two categories: generic APIs, which provide common and generic ...

Data (means ± SD, n = 3) are expressed as fold induction over unstimulated control (CTL). # p < 0.05 versus CTL. ** p < 0.01 versus TNF-α alone. 3.2. OC and OA Modulate TNF-α-Induced Inflammation-Linked miRNAs Expression in Adipocytes and Adipocyte-Derived Exosomes To evaluate ...
(+) At any time, you can check the SD Card status and get the SD card state 00130 by using the HAL_SD_GetStatus() function. This function checks first if the 00131 SD card is still connected and then get the internal SD Card transfer state. 00132...
在每个操作模式下,SD卡都有几种状态,参考表 35‑4,通过命令控制实现卡状态的切换。 表35‑4 SD卡状态与操作模式 操作模式 SD卡状态 无效模式(Inactive) 无效状态(Inactive State) 卡识别模式(Card identification mode) 空闲状态(Idle State) 准备状态(Ready State) 识别状态(Identification State) 数据传输...
