  During debugging for software PWM some jsWarn (in jstimer, function jstPinPWM) have been used.
  Looks to me, that 2nd var of same type is always shown as zero.
  See attached code, where only sequence of 2 vars is changed:

  jsWarn("duty:%f,period:%d,pulse:%d \n",dutyCycle,period,pulseLength);
  jsWarn("duty:%f,pulse:%d,period:%d \n",dutyCycle,pulseLength,period);
  
  

  Result in debug window is:
  WARNING: duty:0.5,period:100000,pulse:0
  WARNING: duty:0.5,pulse:50000,period:0

  Or is %d the wrong format ?

  The 4x4 set is great, couldn't believe. Its still readable, really great.
  Now I can take 2 of my 8X8 leds and show some text.

  This 3x4 is, hmm, its what you said, crazy.
  May be for numbers only (?)
  Anyway its an interesting experiment, thanks for publishing.

  Oh, hopefully, your kids will recognize that old man at the door ;-)
  Being serious now, what was strange in my code, which took away your time ?

  Thanks for your feedback. I will do as suggested.
  One thing I don't understand, there is an res.end in function uploadStd and another one in function uploadPipe. Are they never called, wrong location, or ??

  BTW, do you know about any guideline about setting up a VM for Espruino on Windows 10.

  Sorry, I don't have a linux build. My Ubuntu server is leased in the internet, and my laptop has windows.
  It's tested on ESP32, all my Espruino boards are without WiFi :-(
