Introduction

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

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device
• Adafruit Seesaw helper
• Adafruit MatrixKeypad
• Neopixel

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

Usage Example

To use Trellis as 2 Neotrellis (seesaw):

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

To use TrellisM4 tilled with Neotrellis (seesaw):

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)

Building locally

Zip release files

To build this library locally you'll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix circuitpython-circuitpython-neotrellism4 --library_location .

Sphinx documentation

Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):

python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-theme

Now, once you have the virtual environment activated:

cd docs
sphinx-build -E -W -b html . _build/html

This will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
