#*********************************************************************
# This is the makefile for the ArduiPi OLED library driver
#
#	02/18/2013 	Charles-Henri Hallard (http://hallard.me)
#							Modified for compiling and use on Raspberry ArduiPi Board
#							LCD size and connection are now passed as arguments on 
#							the command line (no more #define on compilation needed)
#							ArduiPi project documentation http://hallard.me/arduipi
# 
# 07/26/2013	Charles-Henri Hallard
#							modified name for generic library using different OLED type
#
# 08/26/2015	Lorenzo Delana (lorenzo.delana@gmail.com)
#							added bananapi specific CCFLAGS and conditional macro BANANPI
