• reset(); save(); not clearing code [SOLVED]

  hello @AdaMan82
  sometime pico have strange behavior too and crash with clean code.
  reflashing take few seconds than trying to identify uncommon behavior in code is timeconsuming.
  i downloaded last firmware to avoid low connexion :)

  Thanks @Gordon .

  i bought an MDBT42Q breakout to try and some pico cause i love form factor.
  next week it's holliday and have some time to play with

  best regards

  ok nobody want helps?

  is the Module MDBT42Q Breakout is enough to start?
  convert it as a bluetooth HID like a keyboard?
  i read some post about that.
  if the device (the breakout) is detected as an hid bluetooth by the os, the html page doesn't have to detect an hid!? it's a keypress detected, no more.

• connecting a rotary encoder to a tablet through bluetooth

  Hello,

  i'm new with bluetooth.
  i would like to connect a rotary encoder to an ipad or an android phone and use the rotation in a web app.

  i'm able to connect the rotary and a pico board to an html page trough the HID feature on my computer.
  but now i would like to communicate to a smart thing (small screen,,,) device via BT.

  Which board do i need to do that, is BT, the good solution ?
  Please advice me.

  regards

  ps: @Gordon there is only one unpinned pico board in stock in the shop! really?

• rotary encoder strange behavior (too many datas)

  in Pico / Wifi / Original Espruino • 1 year, 6 months

  

  OK thank you @Gordon

  the final solution was the pull_up

  function onInit() {
    var value = 0;
    pinMode(A8, 'input_pullup');
    pinMode(A5, 'input_pullup');
    setWatch(function(e) {
      if (e.data) value++ else value--;
      print(value);
      }, A5, {data:A8, repeat:true, edge:'falling'});
  }
  

  the value increases and decreases according to the rotation.

  Hello @gordon
  what is suppose to do?
  e.data is always false when it fire. So, value stepdown what ever i turn clockwise or counterclockwise...

  Thanks Gordon
  i've commented the digitalPulse and print to minimize the interference...
  i send through HID
  i'll try your code tonight.

  no more answer than mine... okay it's not really interesting, nevermind... there is a glitch in the lib...

  and my attempt is not 100% efficient.
  if I turn the encoder quickly, the algorithm slips, and the number advances slowly with a step backwards from time to time...

  a better idea than mine?
