# ili9341 240x320 displays on Pi Pico.
# TSC2007 touch controller.
# Edit the driver import for other displays.

# Demo of initialisation procedure designed to minimise risk of memory fail
# when instantiating the frame buffer. The aim is to do this as early as
# possible before importing other modules.
