nvm – Non-volatile memory

The nvm module allows you to store whatever raw bytes you wish in a reserved section non-volatile memory.

Note that this module can’t be imported and used directly. The sole instance of ByteArray is available at microcontroller.nvm.

class nvm.ByteArray

Presents a stretch of non-volatile memory as a bytearray.

Non-volatile memory is available as a byte array that persists over reloads and power cycles. Each assignment causes an erase and write cycle so its recommended to assign all values to change at once.

Usage:

import microcontroller
microcontroller.nvm[0:3] = b\"\xcc\x10\x00\"

Not currently dynamically supported. Access the sole instance through microcontroller.nvm.

__bool__(self)
__len__(self)

Return the length. This is used by (len)

__getitem__(self, index: slice)
__getitem__(self, index: int)

Returns the value at the given index.

__setitem__(self, index: slice, value: ReadableBuffer)
__setitem__(self, index: int, value: int)

Set the value at the given index.
