/* BEFORE USING THE EXAMPLE PROJECTS.
1. The Example application uses a CPU, PBA and PBB clock of 48MHz.
When using a different frequency setting, the following parameters must be
changed accordingly to ensure proper QMatrix operation.
a. QM_GCLK_CAT_DIV.
b. QM_CAT_CLK_DIV.
c. TOUCH_SPREAD_SPECTRUM_MAX_DEV, when Spread spectrum is enabled.
d. PBA_HZ, when using QDebug/SPI_Master.c
e. TARGET_PBA_FREQ_HZ and TARGET_CPU_FREQ_HZ, when using QDebug/SERIAL.c
2. In the UC3L-Evaluation kit (Rev2), the R42 and R54 (both 470KOhm) resistors
MUST be replaced to 910KOhms.
3. The QTouch library uses PDCA channels 0 and 1.
(QM_DMA_CHANNEL_0, QM_DMA_CHANNEL_1).
Similarly, the QDebug/SERIAL.c uses PDCA channels 2 and 3.
(PDCA_CHANNEL_RX_USART, PDCA_CHANNEL_TX_USART)
4. For QMatrix operation, the Analog comparators channels are used (using the
ACIFB interface) depending on the Y Lines enabled. For example, when
Y lines Y2 and Y7 are enabled the Analog comparator channels 2 and 7
are used by the CAT module for QMatrix operation. The user can uses the rest
of the Analog comparator channels in the main application. The QTouch Library
enables the ACIFB using the Control register (if not already enabled by the main
application) when the touch_qm_sensors_init API is called.
5. When two or more acquisition methods are used, care must be taken such that a
given port pin is not used by more than one method at the same time. The following
pin configuration options available in touch_config_at32uc3l.h must be carefully
chosen to avoid any overlapping.
a. QMatrix Pin Configuration Options.
b. Autonomous QTouch Pin Configuration Options.
c. QTouch Group A Pin Configuration Options.
d. QTouch Group B Pin Configuration Options.
e. Touch Sync Pin option.
