Hi, im trying to use the capsense library by Paul Badger (which i have used before on other arduinos), however getting the following errors, doesnt seem to matter if i change the pins to D2, D4, just get same error. does anyone have a work around?
code:
#include <CapacitiveSensor.h>
/*
* CapitiveSense Library Demo Sketch
* Paul Badger 2008
* Uses a high value resistor e.g. 10M between send pin and receive pin
* Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.
* Receive pin is the sensor pin - try different amounts of foil/metal on this pin
*/
CapacitiveSensor cs_4_2 = CapacitiveSensor(D4,D2); // 10M resistor between pins 4 & 2, pin 2 is sensor pin, add a wire and or foil if desired
void setup()
{
cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF); // turn off autocalibrate on channel 1 - just as an example
Serial.begin(9600);
}
void loop()
{
long start = millis();
long total1 = cs_4_2.capacitiveSensor(30);
Serial.print(millis() - start); // check on performance in milliseconds
Serial.print("\t"); // tab character for debug windown spacing
Serial.print(total1); // print sensor output 1
delay(10); // arbitrary delay to limit data to serial port
}
error
