  Hi Espruinos,

  The title says it all, is it possible to call a function on NRF24 TX not received event?

  Thanks & Regards, Andreas

  Hi Gordon,
  Thanks a lot for your support! It works just fine now. I'm very happy about all the espruino updates and improvements - I really love that thing :)

  Hi Espruinos,

  Since I have updated my Espruinos to 1v67 my NRF does not "answer" anymore.
  To verify I have checked the examples from https://github.com/espruino/EspruinoDocs/blob/master/devices/NRF24L01P.md :

  This works, the green LED can be set via NRF:

  nrf.sendCommand("LED2.set()", function(r) { print("=="+r); });
  =undefined
  

  But 1+2 will return "=undefined" instead of 3:

  nrf.sendCommand("1+2", function(r) { print("=="+r); });
  =undefined
  

  Different to the eaxmple my setup looks like this:

  SPI3.setup({sck:B3, miso:B4, mosi:B5});
  var nrf = require("NRF24L01P").connect( SPI3, A0, A1 );
  
  function onInit() {
  calibrate();
  }
  
  setInterval(function() {
    nrf.masterHandler();
  }, 50);
  

  Does anyone has faced this issue too?

  Thanks & Regards, Andreas

• replace() missing

  in JavaScript • 10 years, 8 months

  

  Hi there,
  For everyone who is also missing the replace function... It took a while for me to find a workaround but one way is to do .split("Arduino") what gives you an array. Than you can loop through this array and add "Espruino" in each loop except the last.

  Hi Gordon,

  Thanks again! It works absolutely fine now. I'm very new in hardware programming and the espruino is really great and a lot of fun to work with!

• More than one button - how to setup?

  in General • 10 years, 9 months

  

  Hi Espruinos!

  In my application I would like to use four buttons C2, C3, C4 and C5.

  The question is, what is the best way to set up these buttons? I tried

  function onInit() {
     //Set the buttons to 0
    C2.write(0);
    C3.write(0);
    C4.write(0);
    C5.write(0);
  }
  
  setWatch(function() {
    l = l + 1;
  }, C5, { repeat: true, edge: "falling", debounce:100});
  
  setWatch(function() {
    m = m + 1;
  }, C4, { repeat: true, edge: "falling", debounce:100});
  
  setWatch(function() {
    n = n + 1;
  }, C3, { repeat: true, edge: "falling", debounce:100});
  
  setWatch(function() {
    o = o + 1;
  }, C2, { repeat: true, edge: "falling", debounce:100});
  

  Each of the buttons is connected to V_bat on the one side and to C2,3,4 or 5 on the other side. But when I press a button (let's say the one connected with C2), the variable "o" does not increase when I press it the first time, when I press it again it jumps from 0 to 2, then it works and jumps from 2 to 3 and so on but with no reproducibly.
  I just want to increase by 1 when a button is pressed.

  Thanks a lot, Andreas

• Out of memory?

  in General • 10 years, 9 months

  

  Hi Gordon,

  I'm using the espruino in combination with a current clamp and log the data to the SD Card. Espruino is my first hardware but it's really fun to work with it, absolutely fantastic! I run out of memory a few times when I do a lot of samples (around 5000 measurements) but as you mentioned this can be fixed when the memory is used more efficiently. I'm looking forward to get more espruino, thanks a lot for the development!
