; //	Name: 		CSR_7Button_Demo_v2.1
; //					- 4/1/06 - version 2.1 (XCH)
; //								- removed function call to output 
; //                                count values 
; //								- added output of CSR_baSwOnMask[0] 
; //								  to LCD
; //					- 3/20/06 - version 2.0 (XCH)
; //							 	- added Calibration routine
; //							    - adjusted settings
; //
; //  For Board:  CY3212-CapSense RevA 
; //	Chip:		CY8C21434-24LFXI
; //
; //  Description:
; // 		This code determines which switch is depressed among 7 switches
; // and displays that switch number on the LCD display. This project uses 
; // Period method of measurement. The display on LCD (port 2 in the LCD UM 
; // parameters) will display the value of CSR_baSwOnMask[0].  This variable
; // holds the on/off status of the 7 switches as a bitmask.  Then once switch
; // is pressed, the switch number is displayed on the LCD display.  The 
; // switch numbers and port pins are assigned in UM wizard.
; // 
; //  Project Settings (in the Device Editor):
; //
; //		Global Resources:
; //			Power Setting [Vcc/SysClk freq]: 5.0V / 24MHz
; //			CPU_Clock:	SysClk/1
; //		
; //		User Module Parameters:
; //			Method: Period
; //			FingerThreshold: 100
; //			NoiseThreshold: 40
; //			BaselineUpdateRate: 40 
; //			ESDDebounce: Disabled
; //
; //  Switch to port settings in CSR wizard (for CY3212 demo board)
; //
; //  SW0 -> P1[4]
; //  SW1 -> P1[6]
; //  SW2 -> P3[0]
; //  SW3 -> P3[2]
; //  SW4 -> P3[3]
; //  SW5 -> P3[1]
; //  SW6 -> P1[3]
; //
; //  Notes:
; //  CSR_1_baSwOnMask -> is an array of BYTEs that contains the data
; //  that determines which button has been pressed.  The first
; //  byte CSR_1_baSwOnMask[0] holds the on/off state of the first 8 switches
; //  in the system, CSR_1_baSwOnMask[1] would hold the on/off state of the 
; //  next 8 switches in the system.  Since there are only 7 switches in
; //  this particular system we only use CSR_1_baSwOnMask[0]. 
; //  Th LSb (bit 0) represents the state of switch0:
; //  0 = off
; //  1 = on
; //  Bit 1 represents switch1 and so on.
