5.6.11.6.3 Debug Interface if USB Bridge board is not available
For the sample applications using the devices that are not supported on EVK2080 and QT600 the
debug interface code is not provided. This is because a separate USB bridge board is required to
read the data and display it on QTouch studio. However in this case the output touch
measurement data can still be viewed using the IAR or AVR Studio IDE when running the code in
debug mode using debug wire or emulator.
The qt_measure_data global variable contains the output touch measurement data. Refer to
section 5.6.4.3 for more information on the data type.
For GCC generated libraries the output touch measurement data can be observed on the watch
window through the pointer pqt_measure_data.
