# To preserve the life of the ePaper display, it is best not to keep it powered up -
# instead putting it to sleep when done displaying, or cutting off power to it altogether.
#
# epdconfig.module_exit() shuts off power to the module and calls GPIO.cleanup()
# The latest epd library chooses to shut off power (call module_exit) even when calling epd.sleep()
# epd.sleep() calls epdconfig.module_exit(), which in turns calls cleanup().
# We can therefore end up in a situation calling GPIO.cleanup twice
#
# Need to cleanup Waveshare epd code to call GPIO.cleanup() only once
# for now, calling epdconfig.module_init() to set up GPIO before calling module_exit to make sure
# power to the ePaper display is cut off on exit
# I have also modified epdconfig.py to initialize SPI handle in module_init() (vs. at the global scope)
# because slepe/module_exit closes the SPI handle, which wasn't getting initialized in module_init
