-# Funkey GPIO keymap config file #
-##################################
-# Format:
-#
-# 	- First all GPIO Pin numbers must be declared (integers separated by commas)
-#	  Example: 0,1,2,3,4,6,7,11,12,13,14,15
-#
-#	- Then the mapping can be done as follows (one line per mapping):
-#	  Pin_number[+Pin_number...], type_mapping, value, str_help_name_pin, str_help_fct_pin
-#	
-#	  args: * Pin_number is the pin number concerned by the maping, 
-#				add +Pin_number for multiple touch mapping (not limited in nb of pins)
-#			* type_mapping can be KEYBOARD or SHELL_COMMAND
-#			* value is :
-#					if type_mapping==KEYBOARD: the keycode from /usr/include/linux/input.h]
-#					if type_mapping==SHELL_COMMAND: the shell command to exec
-#			* str_help_name_pin is a sweet name for the pin (ex: PB5)
-#			* str_help_fct_pin is an help str to indicate the function of this mapping
