  So I wonder if the inconsistency we see is with the puck originating the connection, and not so much with the puck accepting the connection.

  I'm wondering the same thing. I also wonder if caching the connection makes it less reliable. Will make a quick test and see.

  I've got the EspruinoHub up and running with some changes I made to it. Connecting to a puck seems very fast and reliable.

  I actually saw your cloned repo, and I'm testing that right now. One thing I noticed is when you look at the history of the files you modified you can't see the actual changes you made since the whole file seems to be different- due to formatting changes, maybe. I think it would be good if you contributed back your changes upstream, but I personally wouldn't accept a PR in the current state. Just my 2c.

  Ok, 1v90.12 fixes the error and the updated script.

  I see it fail, and then on next press it tries to connect again. However, quite often it will fail- red LED lights up- a few times in a row before the command it's sent successfully.

  There was a bug around promise rejection that was fixed by @Gordon link

  I have upgraded to 1v90.5 and I the issue seems to persist.

  The reason for the rejection is the pucks will disconnect from each other after a minute or two

  This makes sense.

  I noticed that the version provided in the link- 1v90.5- is not present in the "binaries folder".

  FYI The updated firmware provided in the previous post seems to be missing in the "binaries folder".

  @dklinkman thanks for the reply. No, I have not updated the firmware. Will do.

  Hi,
  I just got my Pucks and decided to start playing with them, I'm really impressed and I really like the quality of the hardware and how easy/smooth it was to get up and running.

  Following the tutorial Controlling Other Pucks I ran into an error:

  Uncaught Error: Unhandled promise rejection: undefined at line 34 col
  26 txType.writeValue('Puck.js d5b2').then(()=>{ in function called
  from system

  The code runs perfect initially, but when I click the central Puck after a couple minutes of inactivity I get the previous error. I wont post the source code since it's a copy paste from the tutorial.

  I find the error message confusing since the Promise seems to be handled?

  txCharacteristic.writeValue("toggle()\n").then(function() {
          digitalPulse(LED2, 1, 500); // light green to show it worked
          busy = false;
        }).catch(function() {
          digitalPulse(LED1, 1, 500); // light red if we had a problem
          busy = false;
        });
  

  The peripheral Puck seems to be working OK. I modified the source to handle manual press

  var on = 0;
  function toggle() {
    on = !on;
    digitalWrite(LED, on);
  }
  
  setWatch(toggle, BTN, {edge:'rising', debounce:50, repeat: true});

• [How To] Arduino attachInterrupt

  in General • 9 years, 4 months

  

  I have an arduino sketch that I would like to port JavaScript and run on a pico.
  The sketch is reading input from pins 2 and 3 and then attaching two interrupts to get 0/1 bits.

  What would be the way to achieve this using a pico?

  The following is an excerpt of the sketch I'm using, I could post the whole script but I figured this encompasses the core of my question.

  void ISR_INT0()
  {
      bitCount++;
      flagDone = 0;
      pulseCounter = WAIT_TIME;
  
  }
  
  void ISR_INT1()
  {
      databits[bitCount] = 1;
      bitCount++;
      flagDone = 0;
      pulseCounter = WAIT_TIME;
  }
  
  void setup()
  {
      pinMode(13, OUTPUT);   // LED
      pinMode(2, INPUT);     // DATA0 (INT0)
      pinMode(3, INPUT);     // DATA1 (INT1)
  
      Serial.begin(115200);
      Bridge.begin();
  
      while (!Serial);
  
      attachInterrupt(1, ISR_INT0, RISING);
      attachInterrupt(0, ISR_INT1, RISING);
  
      pulseCounter = WAIT_TIME;
  }
  
  void loop()
  {
      if (!flagDone)
      {
          if (--pulseCounter == 0)
          {
              flagDone = 1;
          }
      }
  
      // if we have bits and we the pulse counter went out
      if (bitCount > 0 && flagDone)
      {
          //... logic removed
          bitCount = 0;
      }
  }
