release.
5.8 PIN Configuration for QTouch Libraries
5.8.1
Pin configurability for QTouch acquisition method is provided for 8Bit AVR’s. QTouch
acquisition method libraries can be used to configure SNS and SNSK on any pins of the
port. But few rules should be followed while assigning the SNS and SNSK on particular
pins. These rules are internal to the library. But QTouch Studio –Pin Configuration Wizard
can be used to assign SNS and SNSK on the pins and rules are internally taken care in the
QTouch Studio Pin Configuration Wizard.
By default, for 4 and 8 channel QTouch acquisition libraries, the channel numbering follows
the pin number of the port.
To use the pin configurability, enable the macro _STATIC_PORT_PIN_CONF_ in the
project options or define the macro in the touch_qt_config.h file.
To use the pin configurability feature, the SNS_array and SNSK_array masks are exported
for the user, which needs to be initialized. These SNS_array and SNSK_array masks can
be taken from the QTouch Studio Pin Configuration Wizard and can be copied at
appropriate place in the main.c file as explained in the example projects provided.
QTOUCH_STUDIO_MASKS macro is used for providing pin configurability feature for
QTouch Acquisition method libraries.

Example Library name
libavr51g2_8qm_4x_2y_krs_2rs.a
libavr25g1s1_16qm_8x_2y_k_0rs.r90
Pin Configuration for QTouch Acquisition Method
SNS_array and SNSK_array takes values that are supplied by the user in main.c files.
This will reduce the code memory foot print of the library.
