DisplayIO widgets for showing flip clock style animattions changing from one number to another.
This driver depends on:
This command can be used to install the PaletteFader:
circup install cedargrove_palettefader
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.
Purchase Feather ESP32-S2 TFT from the Adafruit shop
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-displayio-flipclock
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-displayio-flipclock
To install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-displayio-flipclock
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 adafruit_displayio_flipclock
Or the following command to update an existing version:
circup update
