CircuitPython driver for common low-cost FocalTech capacitive touch chips.
Currently supports FT6206 & FT6236
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-focaltouch/>`_. To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-focaltouch
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-focaltouch
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-focaltouch
Usage Example
=============
.. code-block:: python
import time
import board
import busio
import adafruit_focaltouch
# Create library object (named "ft") using a Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)
ft = adafruit_focaltouch.Adafruit_FocalTouch(i2c, debug=False)
while True:
# if the screen is being touched print the touches
if ft.touched:
print(ft.touches)
else:
print('no touch')
time.sleep(.15)
Documentation
=============
API documentation for this library can be found on `Read the Docs <https://docs.circuitpython.org/projects/focaltouch/en/latest/>`_.
