Puck.js can't send more than 4 IR signals

[Serpen]

I tried the IR tutorial https://www.espruino.com/Puck.js+Infrared

And got my code with 135 array elements, the Puck seems to hang and after 1 min i quit with CTRL C
I also tried the codes of the example, same effect.

So i wrote an loop and i can't get above 4 Array Elements.

PUCKJS, 2v26

const irlen = [];
for (i = 0; i < 20; i++) {
  const dtstart = Date().ms;
  irlen.push(0.5);
  
  Puck.IR(irlen);
  console.log(`IR ${irlen.length} took ${Date().ms-dtstart}`);

/*
IR 1 took 1.89208984375
IR 2 took 1.80053710937
IR 3 took 1.80053710937
IR 4 took 1.8310546875

  Puck.IR(irlen);

}

Restart has no effect, any ideas?

Sorry about this, I've just looked into it.

For 2v26 some changes were contributed that were supposed to improve the timer accuracy, but they appear to have broken the IR transmission.

If you install firmware 2v25, 2v27 when I release it (which will be soon I imagine), or the latest cutting edge build it should now be fixed:

IR 1 took 1.953125
IR 2 took 1.89208984375
IR 3 took 1.86157226562
IR 4 took 1.92260742187
IR 5 took 2.41088867187
IR 6 took 2.01416015625
IR 7 took 2.25830078125
IR 8 took 2.34985351562
IR 9 took 2.22778320312
IR 10 took 2.50244140625
IR 11 took 2.44140625
IR 12 took 2.99072265625
IR 13 took 3.662109375
IR 14 took 3.173828125
IR 15 took 3.90625
IR 16 took 4.91333007812
IR 17 took 6.591796875
IR 18 took 7.38525390625
IR 19 took 7.568359375
IR 20 took 8.75854492187

You might expect to see 10ms + delay for IR 20 but actually the Puck.IR command returns before all the pulses have been output and they continue in the background, so the actual value you see is lower (also why the first 4 appear to take the same length of time!).

okay, thanks. it worked with 2v25 👍
