  thank you so much, it works great ;)

• Software Buttons - Many buttons from just one hardware button

  in Projects • 2 weeks, 5 days

  

  i have espruino Original, and with code I placed above it is not working with button installed on board, I can call this button from IDE by BTN and BTN1 (and button works with other examples), but not with the code I placed above

  i also try it like this, and still doesn't work

  pinMode(B12,"input_pulldown");//i understand B12 is corresponding to BTN or BTN1 on espruino code
  
  var SWBtn = require("https://raw.githubusercontent.c­om/muet/EspruinoDocs/master/modules/SWBu­tton.js");
  
  var mySWBtn = new SWBtn(function(k){
      console.log("Btn on B3 detected " + k); // log key press pattern
    },B12);

  in reply to @allObjects
  sorry but still not clear,
  I used your parts of code above and still have some errors

  do I need some setWatch to make it run?

  is this example below enough to run or there is missing part?
  in my case this code doesn't detect any button

  var SWBtn = require("https://raw.githubusercontent.c­om/muet/EspruinoDocs/master/modules/SWBu­tton.js");
  var mySWBtn = new SWBtn(function(k){
      console.log("BTN1 detected " + k); // log key press pattern
      if        (k === "L"  ) { LED1.set();
      } else if (k === "LS" ) { LED1.reset();
      } else if (k === "LL" ) { LED2.set();
      } else if (k === "LLS") { LED2.reset();
      }
    });

    });
  

  could anyone explain how to change default button pin?

  First I convert my file in Audacity 3.0.2. from mp3 to 16-bit PCM. Then make it mono, next decrease the rate down to 4000Hz, after that i export it and choose "Other Uncompressed files" then Choose "RAW (header-less)" and "Unsigned 8 bit PCM".

  After that I use this converter
  https://www.espruino.com/File+Converter
  and choose .raw file I've just created. In converter select window I choose base64, then I save code
  converted there to TF card.

  Next use this code

  var f = E.openFile("Horse-Angry.raw","r");
  
  var w = new Waveform(2048, {doubleBuffer:true});
  // load first bits of sound file
  w.buffer.set(f.read(w.buffer.length));
  w.buffer2.set(f.read(w.buffer.length));
  var fileBuf = f.read(w.buffer.length);
  // when one buffer finishes playing, load the next one
  w.on("buffer", function(buf) {
    buf.set(fileBuf);
    fileBuf = f.read(buf.length);
    if (fileBuf===undefined) w.stop(); // end of file
  });
  // start output
  analogWrite(A0, 0.5, {freq:40000});
  w.startOutput(A0,11025,{repeat:true});
  

  to play it.

  I have some mp3 samples from internet. I use audacity to decrease rate to 4000Hz but without success, any file I convert by audacity to raw file doesn't work from TF card. There is only some noice. When I use code for short files to run without TF card it is working only with Gordon's code from the web, but not when I convert my files by converter provided here https://www.espruino.com/File+Converter
