# Target machine: Adafruit Feather ESP8266 & FeatherWing IL9341 TFT display
# Notes on the Adafruit ILI9341 TFT interface:
#
# HSPI Signal:	    GPIO Pin Number:	Comments:
#   MOSI		    GPIO13		        HSPI Bus, "Master Out, Slave In" signal    
#   MISO		    GPIO12		        HSPI Bus, "Master In, Slave Out" signal		    
#   SCLK		    GPIO14		        HSPI Bus, "Serial CLock" signal 
#   CS 		    GPIO15		        HSPI Bus, "Chip Select" (aka "Slave Select") signal
#   "DC"		    GPIO0		                Non-standard pin used to facilitate ILI9341 TFT interface	    
#
# Note that the ESP8266 HSPI Interface uses GPIO pins 12, 13, 14, and 15. 
# Also note that this particular Adafruit ILI9341 TFT interface requires one 
# additional signal line (GPIO0). Also, be aware that GPIO12 is actually not
# being used in this particular interface. So, GPIO12 is available for other uses.
