class Flash – access to built-in flash storage

This class gives access to the SPI flash memory.

In most cases, to store persistent data on the device, you’ll want to use a higher-level abstraction, for example the filesystem via Python’s standard file API, but this interface is useful to customise the filesystem configuration or implement a low-level storage system for your application.

Constructors

class rp2.Flash

Gets the singleton object for accessing the SPI flash memory.

Methods

Flash.readblocks(block_num, buf)

Flash.readblocks(block_num, buf, offset)

Flash.writeblocks(block_num, buf)

Flash.writeblocks(block_num, buf, offset)

Flash.ioctl(cmd, arg)

These methods implement the simple and extended block protocol defined by os.AbstractBlockDev.
