This filesystem uses the FAT format and is -stored in the flash after the MicroPython firmware. - -Creating and reading files --------------------------- - -MicroPython on the ESP8266 supports the standard way of accessing files in -Python, using the built-in ``open()`` function. - -To create a file try:: - - >>> f = open('data.txt', 'w') - >>> f.write('some data') - 9 - >>> f.close() - -The "9" is the number of bytes that were written with the ``write()`` method. -Then you can read back the contents of this new file using:: - - >>> f = open('data.txt') - >>> f.read() - 'some data' - >>> f.close() - -Note that the default mode when opening a file is to open it in read-only mode, -and as a text file. Specify ``'wb'`` as the second argument to ``open()`` to -open for writing in binary mode, and ``'rb'`` to open for reading in binary -mode. - -Listing file and more ---------------------- - -The os module can be used for further control over the filesystem. First -import the module:: - - >>> import os - -Then try listing the contents of the filesystem:: - - >>> os.listdir() - ['boot.py', 'port_config.py', 'data.txt'] - -You can make directories:: - - >>> os.mkdir('dir') - -And remove entries:: - - >>> os.remove('data.txt') - -Start up scripts ----------------- - -There are two files that are treated specially by the ESP8266 when it starts up: -boot.py and main.py. The boot.py script is executed first (if it exists) and -then once it completes the main.py script is executed. You can create these -files yourself and populate them with the code that you want to run when the -device starts up. - -Accessing the filesystem via WebREPL ------------------------------------- - -You can access the filesystem over WebREPL using the web client in a browser -or via the command-line tool. Please refer to Quick Reference and Tutorial -sections for more information about WebREPL. |
