Introduction

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

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example

import time
import busio
import board
import adafruit_focaltouch

# Create library object using our Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)

ft = adafruit_focaltouch.Adafruit_FT6XXX(i2c, debug=True)

while True:
    n = ft.touched
    if n:
        print(ft.touches)
