Python library for TSC2007 resistive touch screen driver


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://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.

Works with the Adafruit TSC2007 resistive touch driver.

`Purchase one from the Adafruit shop <http://www.adafruit.com/products/5423>`_


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-tsc2007/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-tsc2007

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-tsc2007

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-tsc2007



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:

.. code-block:: shell

    pip3 install circup

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

.. code-block:: shell

    circup install adafruit_tsc2007

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import board
    import adafruit_tsc2007

    # Use for I2C
    i2c = board.I2C()

    irq_dio = None  # don't use an irq pin by default
    # uncomment for optional irq input pin so we don't continuously poll the I2C for touches
    # irq_dio = digitalio.DigitalInOut(board.A0)
    tsc = adafruit_tsc2007.TSC2007(i2c, irq=irq_dio)

    while True:
        if tsc.touched:
            point = tsc.touch
            if point["pressure"] < 100:  # ignore touches with no 'pressure' as false
                continue
            print("Touchpoint: (%d, %d, %d)" % (point["x"], point["y"], point["pressure"]))
