// FM4_slider_interface.h
/*
	Header code module to support the FM4 S6E2CC GUI slider interface app
	
	Six slider variables are stored in the global float array P_vals[6]. The initial
	values given to this array in the main module are the values used when a
	real-time DSP application first launches on the FM4 S6E2CC board.

  The main component in making this interface work is a UART running through the
	virtual comm port provided along side the CMSIS-DAP debug interface on the board.
