#include "CirquePinnacle.h"
void PinnacleTouch::detectFingerStylus(bool enableFinger = true, bool enableStylus = true, uint16_t sampleRate = 100);

This function will configure the Pinnacle ASIC to detect either finger, stylus, or both.

Tip

Consider adjusting the ADC matrix’s gain to enhance performance/results using setAdcGain().

Warning

This method is not supported on trackpads manufactured on or after 2025. Defer to isRev2025(). Calling this method on newer trackpads will have no effect.

Parameters:
bool enableFinger = true

true enables the Pinnacle ASIC’s measurements to detect if the touch event was caused by a finger or 5.25mm stylus. false disables this feature. Default is true.

bool enableStylus = true

true enables the Pinnacle ASIC’s measurements to detect if the touch event was caused by a 2mm stylus. false disables this feature. Default is true.

uint16_t sampleRate = 100

See the setSampleRate() as this parameter directly calls that function.
