SPI driven CircuitPython driver for PCA9745B constant current LED driver.

Introduction

THIS IS VERY MUCH ALPHA AND IN ACTIVE DEVELOPMENT.

THINGS WILL BREAK!

THIS MAY ALSO BREAK YOUR THINGS!

SPI driven CircuitPython driver for NXP PCA9745B constant current LED driver.

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing from PyPI

.. todo:: Remove the above note if PyPI version is/will be available at time of release.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install fergcorp-circuitpython-pca9745b

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

sudo pip3 install fergcorp-circuitpython-pca9745b

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install fergcorp-circuitpython-pca9745b

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:

pip3 install circup

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

circup install pca9745b

Or the following command to update an existing version:

circup update

Usage Example

.. todo:: Add a quick, simple example. It and other examples should live in the

examples folder and be included in docs/examples.rst.
