Introduction

Documentation Status Discord Build Status

CircuitPython driver for common low-cost FocalTech capacitive touch chips. Currently supports FT6206 & FT6236

Dependencies

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.

Installing from PyPI

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-focaltouch

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

sudo pip3 install adafruit-circuitpython-focaltouch

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-focaltouch

Usage Example

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)
