Use Adafruit TrellisM4 Express board as 2 Neotrellis board. You can you use this to extend TrellisM4 with Neotrellis (seesaw) boards.

This driver depends on:

* `Adafruit CircuitPython <>`_
* `Bus Device <>`_
* `Adafruit Neopixel driver <>`_
* `Adafruit Seesaw driver <>`_
* `Adafruit Matrix Keypad library <>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading the `Adafruit library and driver bundle <>`_.

Usage Example

`How to solder boards together <>`_

To use Trellis as 2 Neotrellis (seesaw):

.. code-block:: python3

from neotrellism4 import NeoTrellisM4
trellis_left = NeoTrellisM4()
trellis_right = NeoTrellisM4(left_part=trellis_left)

To use TrellisM4 tilled with Neotrellis (seesaw):

.. code-block:: python3

from board import SCL, SDA
import busio
from adafruit_neotrellis.neotrellism4 import NeoTrellisM4
from adafruit_neotrellis.neotrellis import NeoTrellis
from adafruit_neotrellis.multitrellis import MultiTrellis
I2C = busio.I2C(SCL, SDA)
trellim4_left = NeoTrellisM4()
trellim4_right = NeoTrellisM4(left_part=trellim4_left)
trelli = [
[trellim4_left, trellim4_right],
[NeoTrellis(I2C, False, addr=0x2F), NeoTrellis(I2C, False, addr=0x2E)]
trellis = MultiTrellis(trelli)
