Note:
2. QTOUCH_STUDIO_MASKS needs to be enabled if using pin configurability .If not enabled
then, static pin mapping will work same as in the earlier versions of the libraries

1. The X lines can be configured on different ports up to a maximum of 3 ports
2. The X lines can be configured on the three different ports.
3. The X lines can be configured on any pins of the ports selected above
4. Provided that these pins do not conflict with the other pins for touch sensing or with the
5. The Y lines can be configured on the any of the pins of the ports selected
6. The PORT_YB is fixed for each device and should be same as the PORT on which the
7. The SMP pin can be configured on any of the IO PORT pins available.

The QMatrix acquisition method libraries needs to be used after configuring X and YA and
YB lines on IO pins of the port as described in the configuration rules described in the
section below. The QTouch Studio Pin Configurator Wizard can be used to assign X, YA,
YB, SMP lines on the pins and rules are internally taken care in the Qtouch Studio Pin
Configurator Wizard.
The snippets can be taken from the QTouch Studio Pin Configurator Wizard and copied to
appropriate places in the main.c and touch_qm_config.h files in the example projects
provided.
Pin Configuration for QMatrix Acquisition Method
Ex: NUM_X_PORTS = 3 (maximum value supported). However the possible values
are NUM_X_PORTS = 1 or NUM_X_PORTS = 2 or NUM_X_PORTS = 3
Ex: X0 on PB2, X1 on PD5, X2 on PE0, X3 on PD1( when NUM_X_LINES= 4),
host application usage.
Ex: Any pins on the PORT_YA and PORT_YB selected.
Suppose, PORT_YA is D, and PORT_YB is C
Since, pin 5 and pin 1 PORTD are already used for X lines(X1, X3), the user can select
any of the remaining pins for YA lines. Suppose that Y0 is on pin2 and Y1 is on pin6
Hence, Y0A – PD2, Y0B – PC2, Y1A – PD6, Y1B – PC6,
Note: Please note that, YA and YB same the share corresponding pins on different ports.
ADC input pins are available.
Ex: PORT_SMP = D
SMP_PIN = 7 as this pin is not being used by touch sensing.
Please take care that the touch sensing pins do not conflict with other IO pins used by
host application
The X lines cannot be shared with the pins on the PORT_YB. (Except in the case of
ATtiny44, ATTiny461, ATTiny861 and ATtiny84)
The YA lines cannot be shared with the pins on the PORT_YB, however the SMP PIN
can be on the PORT_YB.
The YA lines and YB lines should be on the same corresponding pins of the different
ports used.
