Interface to an SD card via the SPI bus
SDCard(bus: busio.SPI, cs: microcontroller.Pin, baudrate: int = 8000000)¶
SD Card Block Interface
Controls an SD card over SPI. This built-in module has higher read performance than the library adafruit_sdcard, but it is only compatible with
bitbangio.SPI. Usually an SDCard object is used with
storage.VfsFatto allow file I/O to an SD card.
Returns the total number of sectors
Due to technical limitations, this is a function and not a property.
Returns: The number of 512-byte blocks, as a number
readblocks(self, start_block: int, buf: WriteableBuffer)¶
Read one or more blocks from the card
