A hacky solution created on a whim to allow for use of GT911-based touch panels on a system with I2C but not GPIO pins (hence, no support for interrupts).
driver.py contains the bulk of the stuff. A systemd service file (touchscreen.service) is also available,
and assumes that the driver is placed at /opt/touchscreen/driver.py. By default this does the bad, bad thing
by running as root - be sure to create proper service users with proper permissions for production usage!
