Fields
cont: Controller<SdMmcSpi<SPIMaster6<Sercom6Pad2<Pc18<PfC>>, Sercom6Pad0<Pc16<PfC>>, Sercom6Pad1<Pc17<PfC>>>, Pc19<Output<PushPull>>>, TS>
Implementations
impl<TS: TimeSource> SDCardController<TS>
[src]
pub fn set_baud<B: Into<Hertz>>(&mut self, baud: B)
[src]
Initializes the MMC card. An error is returned if there is no card or a communications error occurs.
Methods from Deref<Target = Controller<SdMmcSpi<SPIMaster6<Sercom6Pad2<Pc18<PfC>>, Sercom6Pad0<Pc16<PfC>>, Sercom6Pad1<Pc17<PfC>>>, Pc19<Output<PushPull>>>, TS>>
pub fn device(&mut self) -> &mut D
[src]
Temporarily get access to the underlying block device.
pub fn get_volume(
&mut self,
volume_idx: VolumeIdx
) -> Result<Volume, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume_idx: VolumeIdx
) -> Result<Volume, Error<<D as BlockDevice>::Error>>
Get a volume (or partition) based on entries in the Master Boot Record. We do not support GUID Partition Table disks. Nor do we support any concept of drive letters - that is for a higher layer to handle.
pub fn open_root_dir(
&mut self,
volume: &Volume
) -> Result<Directory, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &Volume
) -> Result<Directory, Error<<D as BlockDevice>::Error>>
Open a directory. You can then read the directory entries in a random
order using get_directory_entry
.
TODO: Work out how to prevent damage occuring to the file system while this directory handle is open. In particular, stop this directory being unlinked.
pub fn open_dir(
&mut self,
volume: &Volume,
parent_dir: &Directory,
name: &str
) -> Result<Directory, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &Volume,
parent_dir: &Directory,
name: &str
) -> Result<Directory, Error<<D as BlockDevice>::Error>>
Open a directory. You can then read the directory entries in a random
order using get_directory_entry
.
TODO: Work out how to prevent damage occuring to the file system while this directory handle is open. In particular, stop this directory being unlinked.
pub fn close_dir(&mut self, volume: &Volume, dir: Directory)
[src]
Close a directory. You cannot perform operations on an open directory and so must close it if you want to do something with it.
pub fn find_directory_entry(
&mut self,
volume: &Volume,
dir: &Directory,
name: &str
) -> Result<DirEntry, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &Volume,
dir: &Directory,
name: &str
) -> Result<DirEntry, Error<<D as BlockDevice>::Error>>
Look in a directory for a named file.
pub fn iterate_dir<F>(
&mut self,
volume: &Volume,
dir: &Directory,
func: F
) -> Result<(), Error<<D as BlockDevice>::Error>> where
F: FnMut(&DirEntry),
[src]
&mut self,
volume: &Volume,
dir: &Directory,
func: F
) -> Result<(), Error<<D as BlockDevice>::Error>> where
F: FnMut(&DirEntry),
Call a callback function for each directory entry in a directory.
pub fn open_file_in_dir(
&mut self,
volume: &mut Volume,
dir: &Directory,
name: &str,
mode: Mode
) -> Result<File, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &mut Volume,
dir: &Directory,
name: &str,
mode: Mode
) -> Result<File, Error<<D as BlockDevice>::Error>>
Open a file with the given full path. A file can only be opened once.
pub fn read(
&mut self,
volume: &Volume,
file: &mut File,
buffer: &mut [u8]
) -> Result<usize, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &Volume,
file: &mut File,
buffer: &mut [u8]
) -> Result<usize, Error<<D as BlockDevice>::Error>>
Read from an open file.
pub fn write(
&mut self,
volume: &mut Volume,
file: &mut File,
buffer: &[u8]
) -> Result<usize, Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &mut Volume,
file: &mut File,
buffer: &[u8]
) -> Result<usize, Error<<D as BlockDevice>::Error>>
Write to a open file.
pub fn close_file(
&mut self,
volume: &Volume,
file: File
) -> Result<(), Error<<D as BlockDevice>::Error>>
[src]
&mut self,
volume: &Volume,
file: File
) -> Result<(), Error<<D as BlockDevice>::Error>>
Close a file with the given full path.
