Turtle graphics library for CircuitPython and displayio
|
|
|
|
|
|
Dependencies
|
|
=============
|
|
This driver depends on:
|
|
|
|
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
|
|
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
|
|
|
|
Please ensure all dependencies are available on the CircuitPython filesystem.
|
|
This is easily achieved by downloading
|
|
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.
|
|
|
|
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-turtle/>`_. To install for current user:
|
|
|
|
.. code-block:: shell
|
|
|
|
pip3 install adafruit-circuitpython-turtle
|
|
|
|
To install system-wide (this may be required in some cases):
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo pip3 install adafruit-circuitpython-turtle
|
|
|
|
To install in a virtual environment in your current project:
|
|
|
|
.. code-block:: shell
|
|
|
|
mkdir project-name && cd project-name
|
|
python3 -m venv .venv
|
|
source .venv/bin/activate
|
|
pip3 install adafruit-circuitpython-turtle
|
|
|
|
Usage Example
|
|
=============
|
|
|
|
.. code-block:: python
|
|
|
|
import board
|
|
from adafruit_turtle import Color, turtle
|
|
|
|
turtle = turtle(board.DISPLAY)
|
|
starsize = min(board.DISPLAY.width, board.DISPLAY.height) * 0.9 # 90% of screensize
|
|
|
|
print("Turtle time! Lets draw a star")
|
|
|
|
turtle.pencolor(Color.BLUE)
|
|
|
|
turtle.penup()
|
|
turtle.goto(-starsize/2, 0)
|
|
turtle.pendown()
|
|
|
|
start = turtle.pos()
|
|
while True:
|
|
turtle.forward(starsize)
|
|
turtle.left(170)
|
|
if abs(turtle.pos() - start) < 1:
|
|
break
|
|
|
|
while True:
|
|
pass
|
|
|
