• ES6 Constructs NOT available in modules

  In the ide I think you may get warnings, however the interpreter itself can handle the code.

  From memory the acorn parser in the ide does not handle things like arrow functions.

  It looks like you are using an esp8266 - and this has very limited memory - you could try the save on send option in the ide, and this might out put the code into flash, saving more ram space.

• New version with V3.1

  in ESP32 • 1 week, 2 days

  

  Ok. And I can do the same branch for build tools.

  Do you want to raise an issue - or I can - and put in there the make file changes for the ESP-idf and then I can see if get that compiling as a first step?

  How did you want to proceed?

  Did you want to put this into the esp32 branch and then I can see if I can get a build?

  Looks like 1344k - pretty tight then!

  The firmware size is not that important as it’s just flash space right?

  What size did we make the partitions last time we changed?

• Sine wave oscillator

  in General • 1 week, 6 days

  

  At start up - why not create a 0-89 indexed float array and store the value of the sin at each index. Then when you want to use the value - it's just a simple lookup - no computation. You just need to do some manipulation of the index - so for 100deg look up the 80 degree value - and for > 180 flip the sign...

  The compares might be slower so you could store the whole array - or 0-179.

  You could even store fixed point values rather than floating point.

• Espruino Wifi Socket recovery

  Push out the 5 secs - make it say 30 or 60 seconds.

  I would guess that you are running out of sockets. You could tell by, on connect, print out the socket number. These should get reused - but I think you are re- connecting so quickly that they don't get a chance to get reused.

• How to define and reference an array of CONSTANTS in deployed module

  in JavaScript • 3 weeks

  

  Go back and have a look at the sample: http://www.espruino.com/Writing+Modules

  You need to add a constructor function and export the reference to that.

  The bind your contants to that function. so if you called it myMod :

  var myMod = function (options) {
    this.options = {}    || options;
  };
  
  
  myMod.C = {
    U : "up",
    D : "down",
    L : "left",
    R : "right",
    N : "north",
    E : "east",
    S : "south",
    W : "west",
    T : "top",
    M : "middle",
    B : "bottom"
  };
  
  exports = myMod;
  

  my_mod=new myMod();
  print my_mod.C.U;
  

• New interpreter error: LOW_MEMORY,MEMORY

  Really need to see your code
