6.3.13 Code and Data Memory requirements for UC3L
6.3.13.1 QMatrix method memory requirement
The Table below captures the Typical Code & Data Memory requirement for the QTouch Library
when QMatrix method is used standalone.
In addition to the Data memory captured in the Table, the QMatrix method requires additional
Data Memory that must be provided to the Touch Library for storing the Signals, References,
Sensor information and Touch status. This data memory is provided by the Host Application to
the QTouch Library as QMatrix data block. The size of this Data memory block depends on the
Number
PRIV_QM_DATA_BLK_SIZE macro in touch_api_at32uc3l.h calculates the size of this data
memory block. For example, for the UC3L Evaluation kit Rev2 that has 6 Sensors including 1
Wheel and 5 Buttons, the QMatrix data block memory size is 236 bytes.
Note: This Typical Code memory usage is achieved when only QMatrix Regular API is used in
the application. Usage of QMatrix Helper API would consume additional Code memory. Also,
the Code and Data memory indicated in the Table do not account for Example QMatrix
application.
6.3.13.2 QTouch Group A/B method memory requirement
The Table below captures the Typical Code & Data Memory requirement for the QTouch Library
when QTouch Group A or QTouch Group B Sensor is used standalone. (Additional Data memory
will be required when both Group A and Group B are used at the same time.)
In addition to the Data memory captured in the Table, the QTouch Group A/B method requires
additional Data Memory that must be provided to the Touch Library for storing the Signals,
References, Sensor information and Touch status. This data memory is provided by the Host
Application to the QTouch Library as QTouch data block. The size of this Data memory block
depends on the Number of Sensors and the Number of Wheel or Slider configured. Refer
PRIV_QTx_DATA_BLK_SIZE macro in touch_api_at32uc3l.h. For example, when 6 Sensors are
used that include 1 Wheel, 1 Slider and 2 Button, the QTouch GroupA/B data block memory size
is 184 bytes.

For the case of QTouch Group A and Autonomous QTouch Example projects, the
‘QT600-USB Bridge’ board can be use to capture the QDebug debug data in the QTouch
Studio.
