|
||
|
|
|
||
|
|
To use the hardware SDIO, include it in your code:
|
||
|
|
```c++
|
||
|
|
#include "SDIO.h"
|
||
|
|
|
||
|
|
SDIOClass sdio;
|
||
|
|
```
|
||
|
|
|
||
|
|
#### **`begin();`**
|
||
|
|
|
||
|
|
Connects to the SDIO card, using 4-bit mode.
|
||
|
|
|
||
|
|
Returns true on success, false on failure.
|
||
|
|
On failure, use `getError()`.
|
||
|
|
|
||
|
|
#### **`uint8_t end();`**
|
||
|
|
|
||
|
|
Disconnects from the SDIO card.
|
||
|
|
|
||
|
|
#### **`uint32_t getBlockSize();`**
|
||
|
|
|
||
|
|
Returns the block size.
|
||
|
|
|
||
|
|
#### **`uint8_t readBlocks(uint32_t block, uint8_t* dst, size_t blocks);`**
|
||
|
|
|
||
|
|
Read the given number of blocks into dst buffer in blocking mode.
|
||
|
|
|
||
|
|
#### **`uint8_t writeBlocks(uint32_t block, const uint8_t* src, size_t blocks);`**
|
||
|
|
|
||
|
|
Writes the given number of blocks from the buffer in blocking mode.
|
||
|
|
|
||
|
|
#### **`uint8_t eraseBlocks(uint32_t startBlock, uint32_t endBlock);`**
|
||
|
|
|
||
|
|
Erases the blocks from start block to end block.
|
||
|
|
|
||
|
|
#### **`HAL_SD_ErrorTypedef getError();`**
|
||
|
|
|
||
|
|
Returns the last error type.
|
||
|
|
|
||
|
|
#### **`uint64_t getCapacity();`**
|
||
|
|
|
||
|
|
Returns the SD Card capacity.
|
||
|
|
|
||
|
|
#### **`uint8_t getType();`**
|
||
|
|
|
||
|
|
Returns the type of the SD Card
|
||
|
|
|
||
|
|
#### **`uint16_t getRCA();`**
|
||
|
|
|
||
|
|
Returns the RCA register.
|
||
|
|
|
||
|
|
#### **`HAL_SD_CIDTypedef getCID();`**
|
||
|
|
|
||
|
|
Returns the CID register.
|
||
|
|
|
||
|
|
#### **`HAL_SD_CSDTypedef getCSD();`**

||
|
|
|
||
|
