Talking to LightwaveRF 433MHz

Ahh, thanks. So I guess that's what I thought - your original code was probably fine, but was running a bit too slowly to put the pulses end to end.

And I was trying to be too clever in my code. Due to the awesomeness of JavaScript, it looks like the ternary operator doesn't treat the string "0" as false. Also I think the pausing between isn't working right because setInterval is always calling back every 10ms, rather than 10ms + the length of the signal.

Try:

// 1 added to front, and 10 converted to 0 already
var encode = [
"1111010",
"1110110",
"1110101",
"1110011",
"1101110",
"1101101",
"1101011",
"1011110",
"1011101",
"1011011",
"1010111",
"0111110",
"0111101",
"0111011",
"0110111",
"0101111"];
function sendNibbles(nibbles) {
  var repeat = 12;
  var cmdStream = "var p=digitalPulse;";
  var sigLength = 0.5;
  cmdStream+="p(TX,1,0.25);p(TX,0,0.25);";­ //msg start bit
  nibbles.forEach(function(nibble) {
    encode[nibbble].split("").forEach(functi­on(bit) {
        var length = (bit=="1")?0.25:1.25;
        cmdStream+="p(TX,1,0.25);p(TX,0,"+length+");";
        sigLength += 0.25+length;
    });
  });
  cmdStream+="p(TX,1,0.25);";­ //msg end bit
  sigLength += 0.25;
  var interval = setInterval(function() {
    eval(cmdStream);
    if (repeat-- == 1) clearInterval(interval);
  }, sigLength+10.25); // delay 10250us between repeats
}
