Comments |
|---|---|---|
|
_QTOUCH_ |
This macro has to be defined in order to use QTouch libraries. |
|
|
SNS & SNSK |
|
To be used if only single port pair is needed for the design |
|
SNS1 – SNSK1 & SNS2 – SNSK2 |
|
To be used if two port pairs are needed for the design |
|
QT_NUM_CHANNELS |
4, 8, 12, 16 for tinyAVR, megaAVR and XMEGA device libraries and 8, 16, 32 for UC3 device libraries. |
|
|
_ROTOR_SLIDER_ |
Rotor / slider can be added to the design, if this symbol is defined |
A library with rotor / slider functionality already available needs to be selected if this macro is to be enabled |
|
_DEBUG_INTERFACE_ |
The debug interface code in the example application will be enabled if this macro is enabled. |
This will enable the application to output QTouch measurement values to GPIO pins, which can be used by a USB bridge to view the output on Hawkeye or QTouch Studio. This feature is currently supported by EVK/TS 2080A and QT600 boards. |
|
QT_DELAY_CYCLES |
1 to 255 |

Refer to section 5.8.1 |
|
_STATIC_PORT_PIN_CONF_ |
This macro needs to be defined only in case of 4 and 8 channel libraries with interport configuration and pin configurability. |
