Besides general properties there exist also properties which are specific to a certain sample method. These properties can be accessed via tlSensors.data[<n>].tlStructSampleMethod.<sampleMethod>.<property>, for example tlSensors.data[0].tlStructSampleMethod.touchRead.pin.

Sample method CVD

pin

int tlSensors.data[<n>].tlStructSampleMethod.CVD.pin

Pin to which the sensor is connected.

useNChargesPadding

bool tlSensors.data[<n>].tlStructSampleMethod.CVD.useNChargesPadding

Set to true to ensure that the CVD method always takes the same amount of time. This means that TouchLib will always use nChargesMax measurements, even if fewer measurements would be sufficient.

Default: true.

nChargesMin

bool tlSensors.data[<n>].tlStructSampleMethod.CVD.nChargesMin

Minimum number of measurements that the CVD method should take.

Default: depends on processor; see table below.

nChargesMax

bool tlSensors.data[<n>].tlStructSampleMethod.CVD.nChargesMax

Maximum number of measurements that the CVD method should take.

Default: depends on processor; see table below.

chargeDelaySensor

bool tlSensors.data[<n>].tlStructSampleMethod.CVD.chargeDelaySensor

Delay in microseconds during charging or discharging the sensor.

Default: depends on processor; see table below.

chargeDelayADC

bool tlSensors.data[<n>].tlStructSampleMethod.CVD.chargeDelayADC

Delay in microseconds during charging or discharging the sensor.

Default: depends on processor; see table below.

Processor default for nChargesMin default for nChargesMax default for chargeDelaySensor default for chargeDelayADC
ATmega (Arduino UNO, Mega, Lilypad USB etc) 1 1 0 0
STM32F20x (Particle Photon etc) 1 1 0 0
Freescale MK20DX256 (Teensy 3.2) 4 4 0 0

Sample method resistive

pin

int tlSensors.data[<n>].tlStructSampleMethod.resistive.pin

Pin to which the sensor is connected.

gndPin

int tlSensors.data[<n>].tlStructSampleMethod.resistive.gndPin

Input / output pin to which the negative side of the sensor is connected. Set to -1 if the negative side is not connected to a pin but always connected to groud instead.

If a resistive sensor is also to be used as a capacitive sensor, the negative side must always be connected to an input / output pin so the Arduino can set this pin as input (floating) in order to use it as a capacitive sensor and set as output (low / ground) in order to use it as a resistive sensor.

useInternalPullup

bool tlSensors.data[<n>].tlStructSampleMethod.resistive.useInternalPullup

Set to true if the internal pull up on the analog input of the Arduino should be used for this sensor.

If a resistive sensor is also to be used as a capacitive sensor, this must be set to true and no external pull up should be connected. The Arduino can then disable the internal pull up this (make the pin floating) in order to use it as a capacitive sensor and enable it to use it as a resistive sensor.

valueMax

int32_t valueMax

Maximum value that sensor should report. If actual value of the sensor is larger than this, the value will be clipped to valueMax.

This property is currently not used.

Sample method touchRead

pin

int tlSensors.data[<n>].tlStructSampleMethod.touchRead.pin

Pin to which the sensor is connected.
