DaisyDuino button example not working

Arduino
1

Hi

I am trying to run the example code for button on the daisy seed. for the button.Init function I have an error saying it needs 4 parameters (the example has three) and that the 4th param is the mode. Does anyone know what I should be entering here? I tried 1 and 0 and the led is flickering not at full strength. It’s not reacting to the button at all

here is the code

// Title: Button
// Description: Turn an led on and off with a button
// Hardware: DaisyHardware
// Author: Ben Sergentanis
// Breadboard:
// https://raw.githubusercontent.com/electro-smith/DaisyExamples/master/seed/Button/resources/Button_bb.png
// Schematic:
// https://raw.githubusercontent.com/electro-smith/DaisyExamples/master/seed/Button/resources/Button_schem.png

#include "DaisyDuino.h"

static DaisyHardware seed;

Switch button;

void setup() {
  // setup the button
  // update at 1kHz, no invert, on pin 28
  button.Init(1000., true, 26, t);

  pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
  // Debounce the button
  button.Debounce();

  // If the button is pressed, turn the LED on
  digitalWrite(LED_BUILTIN, button.Pressed());

  // wait 1 ms
  delay(1);
}

oh and I tried t in this code here - that’s because I saw it in the c++ docs as a type (toggle) and thought it may work - it didn’t :slight_smile:

Oh wait - I made a very simple mistake - I was using the leg number not the Dpin number to refer to my button. Now that is fixed when I set the 4th parameter to 0, it is dim and gets brighter in response to the button, 1 is on all the time, and 2 responds to the button as a momentary button.

I’ll leave this here for anyone else

also see this thread if you’re still interested in the mode parameter:

thanks, ok here is a very basic question, everyone keeps saying on that thread that the source code is the best documentation for daisyduino, where do I find that? I’ve generally been looking at the daisySp documentation.

Looks like the github repo is at:
