# Fullmo MovingCap CODE - micropython example.
# original file name: refGoExtensionExampleEvt.py
# requires turnTRACK firmware v50.00.05.05_RE higher

# This example shows how to mimic the original XENAX protocol events @H, @S1, @S2..
# Note: This is for demonstration purposes. For practical applications, 
# calling the text-based "refgo" interface 10 times per milliseconds is a waste
# of CPU time, but it demonstrates how fast MovingCap can run micropython code,
# even if it includes string processing. 
# With events enabled and used, the main loop is processed in around 0.125 milliseconds.
