Maximum number of rotor / sliders supportedNOTE:• For 8-bit devices, ports which have less than 8 pins cannot be used by the QTouchacquisition method libraries. Check the data sheet to determine the number of pinssupported for each portPort combinations supported for SNS and SNSK pin configurationsFor the list of all ports supported for each device please refer to the library selection guide. Thereare no limitations for AVR devices (8bit and 32 bit) on the combination of SNS and SNSK port tobe 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 forATSAMAA, BB, CC, AB, BA, AC, CA, BC, CBTips on pin assignments for the sensor design using one pair of SNS/SNSKportsThis section lists tips on selecting the pin assignments when using a single port pair for the SNSand SNSK Pins.Design choice for the sensorSNSK & SNS pins are on differentports, number of channels = 4SNSK & SNS pins are on differentports, number of channels = 8Example Port configuration with pin assignments• If the SNS1(C) and SNSK1(B) pins are on two different ports, theuser should mount the sensors onto the corresponding pins suchas (PC0,PB0), (PC1,PB1), (PC2,PB2) and (PC3,PB3), when pinconfigurability is not used.• In case of pin configurability, sensors should be mounted on thepins as selected based on rules illustrated in section 5.8.1• If the SNS1(C) and SNSK1(B) pins are on two different ports, theuser should mount the sensors onto the corresponding pins suchas (PC0,PB0), (PC1,PB1), (PC2,PB2) and so on, When pinconfigurability is not used.• When using pin configurability, sensors should be mounted on thepins 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 tochannel 7 will be on (PC7, PB7) pins.• When using pin configurability, channel should be assigned asgiven in section 5.6.6.1.1.2•SNSK & SNS pins are on differentports, number of channels = 32when using UC3 device• If the SNS1(B) and SNSK1(A) pins are on two different ports, theuser should mount the sensors onto the corresponding pins suchas (PB0,PA0), (PB1,PA1), (PB2,PA2)..• In this case channel 0 will be on (PB0, PA0) pins, channel 1 will beon (PB1, PA1) pins and so on up to channel 31 will be on (PB31,PA31) pins.828207K-AT42-09/11
SNSK & SNS pins are on thesame port, number of channels =2• If the use of SNS1(A) and SNSK1(A) pins are on the same port,the user should always have the configuration (PA0, PA1) & (PA2,PA3). In this case channel 0 will be on (PA0, PA1) pins; channel 1will be on (PA2, PA3) pins. The even pins of the port are used asSNS1 pins and odd pins of the port are used as SNSK1 pins• When pin configurability is used, sensors should be mounted onthe pins as selected as per the rules illustrated in section 5.8.1 andchannels should be assigned as given in section 5.6.6.1.1.4SNSK & SNS pins are on thesame port, number of channels =4• If the use of SNS1(A) and SNSK1(A) pins are on the same port,the user should always have the configuration (PA0, PA1), (PA2,PA3), (PA4, PA5) & (PA6, PA7). In this case channel 0 will be on(PA0, PA1) pins, channel 1 will be on (PA2, PA3) pins and so onup to channel 4 will be on (PA6, PA7) pins. The even pins of theport are used as SNS1 pins and odd pins of the port are used asSNSK1 pins, when pin configurability is not being used.• When using pin configurability, sensors should be mounted on thepins as selected as per the rules illustrated in section 5.8.1 andchannels should be assigned as given in section 5.6.6.1.1.4SNSK & SNS pins are on thesame port, number of channels =16( Available only for UC3 devices ifmore than 4 channels are to beused on a single port. FortinyAVR, megaAVR, XMEGAdevices up to 8 channels withSNS and SNSK on same portsrefer to section 5.7.1.5.2 )SNSK & SNS pins are on thesame port, number of channels =16( Available only for SAM devices)• This configuration is available only for UC3 library variants.• In the use of SNS(A) and SNSK(A) pins are on the same port, theuser should always have the configuration (PA0, PA1), (PA2,PA3), (PA4, PA5) & so on. In this case channel 0 will be on (PA0,PA1) pins, channel 1 will be on (PA2, PA3) pins and so on up tochannel 15 will be on (PA30, PA31) pins. The even pins of the portare used as SNS pins and odd pins of the port are used as SNSKpins• If the use of SNS(A) and SNSK(A) pins are on the same port, theuser should always have the configuration (PA0, PA1), (PA2,PA3), (PA4, PA5), (PA6, PA7) and so on.• In this case channel 0 will be on (PA0, PA1) pins, channel 1 will beon (PA2, PA3) pins and so on up to channel 15 will be on (PA30,PA31) pins.• The even pins of the port are used as SNS pins and odd pins ofthe port are used as SNSK pinsPort combinations supported for two port pair SNS and SNSK pinconfigurationsFor the list of all ports supported for each device please refer to the library selection guide.
