# ili9341 240x320 displays on Pyboards. On a Pyboard 1.1 frozen bytecode
# is required.
# 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.
