#
# This script serves as a confidence check that the pipe interface to
# the pigpio library is ok.
#
# The script uses gpio 4 (P1-7).  Make sure that nothing (or only a LED)
# is connected to gpio 4 before running the script.
#
# To run the script
# sudo pigpiod # if not already running
# ./x_pipe # on the Pi running pigpiod
#
# Some tests are statistical in nature and so may on occasion fail.
# Repeated failures on the same test or many failures in a group
# of tests indicate a problem.
