#define _QMATRIX_

The following rules need to be followed while configuring the QTouch library for QTouch acquisition method.

1. Always setup the following to have valid values #define QT_NUM_CHANNELS

#define QT_DELAY_CYCLES

The value for QT_NUM_CHANNELS should match the library chosen. For example, when using libavr5g4-64qm-8x-8y-krs-4rs.a library, set QT_NUM_CHANNELS to 64 only.

1. Define the following for X lines used #define NUM_X_LINES

#define NUM_X_PORTS

#define PORT_NUM_1

#define PORT_NUM_2 <value, if using 2 X ports> #define PORT_NUM_3 <value, if using 3 X ports> #define PORT_X_1

#define PORT_X_2 <value, if using 2 X ports> #define PORT_X_3 <value, if using 3 X ports>

1. Define the following macros for Y lines used #define NUM_Y_LINES

#define PORT_YA

#define PORT_YB

1. If ports for YA and YB are the same, define macro #define SHARED_YAYB 1 5 Define these macros for SMP pins used #define PORT_SMP

#define SMP_PIN

1. If using a library with rotors and sliders, define the macros below: #define ROTOR_SLIDER #define QT_MAX_NUM_ROTOR_SLIDER

The value for QT_MAX_NUM_ROTOR_SLIDER should match the library chosen. For example, when using libavr5g4-64qm-8x-8y-krs-4rs.a library, set QT_MAX_NUM_ROTOR_SLIDER to 4 only.

1. If using a debug interface, define #define DEBUG_INTERFACE Custom user configuration can be in below section. Define the Number of ROTORS/SLIDERS used. Possible values: 0 ( if ROTOR_SLIDER is not defined) 1, 2, 4 and 8 ( if ROTOR_SLIDER is defined) Depending on the library used.Please refer to the QTouch library user guide.pdf and library selection guide.xls more information on selecting the number of channels.
