Driver for SPD1656 driven ACeP (7-color) e-paper displays.

Please note that we do not have Blinka support for this yet. So it won't work with a Raspberry Pi.

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://circuitpython.org/libraries>_ or individual libraries can be installed using circup <https://github.com/adafruit/circup>_.

This supports the common 4" and 5.65" ACeP displays.

• Waveshare 4"
• Waveshare 5.65"
• Pimoroni 5.7" (Likely the same as 5.65".)
• Pimoroni 4"

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-spd1656/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-spd1656

To install system-wide (this may be required in some cases):

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-spd1656

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-spd1656

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

.. code-block:: shell

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

.. code-block:: shell

circup install adafruit_spd1656

Or the following command to update an existing version:

.. code-block:: shell

circup update

Usage Example

.. code-block:: python
