displayio driver for GC9A01A displays.
This driver depends on:
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.
Adafruit 1.28" 240x240 Round TFT GC9A01A
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-gc9a01aTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-gc9a01aTo 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-gc9a01aMake sure that you have circup installed in your Python environment. Install it with the following command if necessary:
pip3 install circupWith circup installed and your CircuitPython device connected use the following command to install:
circup install adafruit_gc9a01aOr the following command to update an existing version:
