.. class:: pyb.SD(dat_pin, dat_pin_af, clk_pin, clk_pin_af, cmd_pin, cmd_pin_af)
.. class:: pyb.SD([pins_tuple])
Create a SD card object. Data, clock and cmd pins must be passed along with
their respective alternate functions.
Create a SD card object. In order to initalize the card, give it a 6-tuple
``(dat_pin, dat_af, clk_pin, clk_af, cmd_pin, cmd_af)`` with the data, clock
and cmd pins together their respective alternate functions.
Methods
-------
.. method:: sd.enable()
.. method:: sd.init([pins_tuple])
Enable the SD card and mount it on the file system. Accesible as ``/sd``.
Enable the SD card.
.. method:: sd.disable()
.. method:: sd.deinit()
Disable the SD card and remove it from the file system.
Disable the SD card (also unmounts it to avoid file system crashes).
.. method:: sd.mount()
Mount the SD card on the file system. Accesible as ``/sd``.
.. method:: sd.unmount()
Unmount the SD card from the file system.
