The QMatrix Example projects demonstrate the QMatrix operation on the UC3L Evaluation Kit
(Rev 2). QMatrix SMP discharge mode hardware arrangement is used for the UC3L Evaluation
Kit with 6 X Lines and 2 Y Lines. Using the 12 Touch Channels (6x2), 6 Touch Sensors are
formed that include a Rotor (that uses six Touch Channels) and 5 keys (each using one Touch
channel).
The Example projects demonstrate the QMatrix measured data and Touch Status usage using
the LED Demo application. The onboard LED0, LED1, LED2 and LED3 are set when the Touch
Position of the Rotor position varies from 0 to 255. By Touching the up key (^), left key (<),
play/pause key (>/||) and right key (>), the LED0, LED1, LED2 and LED3 can be individually
cleared. When the down key (v) is touched, it clears all LEDs.

The Autonomous QTouch Example projects demonstrate the Autonomous QTouch Sensor API
usage.
Asynchronous Timer peripheral event.
Note 1: The Example Projects also support relaying the Touch Sensor debug information to the
“QTouch Studio – Touch Analyzer” PC Software. The QTouch Studio can also be used for
setting the Sensor and Global configuration parameters of the QTouch Library at run-time.
The QTouch Studio can be downloaded from the following path.

The QDebug two-way debug protocol used by the Example project to communicate (transmit or
receive touch debug data) with the QTouch Studio can be found in the following installation path.

For the UC3L Evaluation kit (uc3l_xx_qm_ek_example Example project) to connect with
the QTouch Studio using the USB interface, the UC3B MCU on the UC3L Evaluation kit
must be Flashed with ISP and Program binaries. The procedure to flash the binaries is
available in the readme note in the following path.
