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__() bool
__len__() int

Return the length. This is used by (len)

__getitem__(index: slice) bytearray
__getitem__(index: int) int

Returns the value at the given index.

__setitem__(index: slice, value: _typing.ReadableBuffer) None
__setitem__(index: int, value: int) None

Set the value at the given index.
