############ Logitech F310 Gamepad Controller Main - parser_main.py ##########
# Original Author: John Zeller
# Description: Parser_Main polls the data in a python dictionary to check the
#			   states of several buttons coming from parser_core.py. Once it
#			   reads these states, it will display them for reference on the
#			   terminal it was launched in

### NOTES #####################################################################
# 1) LEAVE MODE 'OFF' there is no support in parser_main.py for MODE ON
# 2) Naturally the gamepad sends the following values:
# 	LJ/RJ - Down: 0-127
# 	LJ/RJ - Up: 255-128
# 	LJ/RJ - Left: 255-128
# 	LJ/RJ - Right: 0-127
###############################################################################

### Buttons/Joys Represented: #################################################
# A, B, X, Y, RB, LB, LJButton, RJButton, Back, Start, Middle
# RT, LT, LeftJoy, RightJoy, Left, Right, Up, Down
