# Project Modules
#
#| Note: This is the only section you probably want to modify
#| Each module is defined by it's own folder (e.g. Scan/Matrix represents the "Matrix" module)
#| All of the modules must be specified, as they generate the sources list of files to compile
#| Any modifications to this file will cause a complete rebuild of the project
#| Please look at the {Scan,Macro,USB,Debug}/module.txt for information on the modules and how to create new ones
##| Deals with acquiring the keypress information and turning it into a key index
set( ScanModule "avr-capsense" )
##| Uses the key index and potentially applies special conditions to it, mapping it to a usb key code
set( MacroModule "buffer" )
##| Sends the current list of usb key codes through USB HID
set( USBModule "pjrc" )
##| Debugging source to use, each module has it's own set of defines that it sets
set( DebugModule "full" )
