# This script is used to dump Z80 instruction timing data by running the
4
# instructions through the Arduino Z80 dongle and parsing the dump output.

# It needs:

#   1. Arduino Z80 dongle: http://www.baltazarstudios.com
7
#   2. Instructions data file: '../../resources/opcodes-??.txt'

# Needs pyserial from https://pypi.python.org/pypi/pyserial
