uos module contains functions for filesystem access and
Change current directory.
Get the current directory.
This function returns an iterator which then yields 3-tuples corresponding to the entries in the directory that it is listing. With no argument it lists the current directory, otherwise it lists the directory given by dir.
The 3-tuples have the form (name, type, inode):
- name is a string (or bytes if dir is a bytes object) and is the name of the entry;
- type is an integer that specifies the type of the entry, with 0x4000 for directories and 0x8000 for regular files;
- inode is an integer corresponding to the inode of the file, and may be 0 for filesystems that don’t have such a notion.
With no argument, list the current directory. Otherwise list the given directory.
Create a new directory.
Remove a file.
Remove a directory.
Rename a file.
Get the status of a file or directory.
Get the status of a fileystem.
Returns a tuple with the filesystem information in the following order:
f_bsize– file system block size
f_frsize– fragment size
f_blocks– size of fs in f_frsize units
f_bfree– number of free blocks
f_bavail– number of free blocks for unpriviliged users
f_files– number of inodes
f_ffree– number of free inodes
f_favail– number of free inodes for unpriviliged users
f_flag– mount flags
f_namemax– maximum filename length
Parameters related to inodes:
f_flagsparameter may return
0as they can be unavailable in a port-specific implementation.
Sync all filesystems.
Return a bytes object with n random bytes. Whenever possible, it is generated by the hardware random number generator.
Duplicate or switch the MicroPython terminal (the REPL) on the given
stream-like object. The stream_object argument must implement the
write()methods. The stream should be in non-blocking mode and
Noneif there is no data available for reading.
After calling this function all terminal output is repeated on this stream, and any input that is available on the stream is passed on to the terminal input.
The index parameter should be a non-negative integer and specifies which duplication slot is set. A given port may implement more than one slot (slot 0 will always be available) and in that case terminal input and output is duplicated on all the slots that are set.
Noneis passed as the stream_object then duplication is cancelled on the slot given by index.
The function returns the previous stream-like object in the given slot.
