NOTE:
5.7.1.5
For the list of all ports supported for each device please refer to the library selection guide. There
are no limitations for AVR devices (8bit and 32 bit) on the combination of SNS and SNSK port to
be used from QTouch libraries 4.0 release onwards.
For ATSAM devices the one port pair combinations supported are given below in the table.
One port pair supported combinations for
ATSAM
5.7.1.5.1
This section lists tips on selecting the pin assignments when using a single port pair for the SNS
and SNSK Pins.
Design choice for the sensor
SNSK & SNS pins are on different
ports, number of channels = 4
SNSK & SNS pins are on different
ports, number of channels = 8
SNSK & SNS pins are on different
ports, number of channels = 32
when using UC3 device
•
For 8-bit devices, ports which have less than 8 pins cannot be used by the QTouch
acquisition method libraries. Check the data sheet to determine the number of pins
supported for each port

If the SNS1(C) and SNSK1(B) pins are on two different ports, the
user should mount the sensors onto the corresponding pins such
as (PC0,PB0), (PC1,PB1), (PC2,PB2) and (PC3,PB3), when pin
configurability is not used.
In case of pin configurability, sensors should be mounted on the
pins as selected based on rules illustrated in section 5.8.1
If the SNS1(C) and SNSK1(B) pins are on two different ports, the
user should mount the sensors onto the corresponding pins such
as (PC0,PB0), (PC1,PB1), (PC2,PB2) and so on, When pin
configurability is not used.
When using pin configurability, sensors should be mounted on the
pins as selected based on rules illustrated in section 5.8.1
When pin configurability is not used, channel 0 will be on (PC0,
PB0) pins, channel 1 will be on (PC1, PB1) pins and so on up to
channel 7 will be on (PC7, PB7) pins.
When using pin configurability, channel should be assigned as
given in section 5.6.6.1.1.2
If the SNS1(B) and SNSK1(A) pins are on two different ports, the
user should mount the sensors onto the corresponding pins such
as (PB0,PA0), (PB1,PA1), (PB2,PA2)..
In this case channel 0 will be on (PB0, PA0) pins, channel 1 will be
on (PB1, PA1) pins and so on up to channel 31 will be on (PB31,
PA31) pins.
