  Hi at all,

  first of all thank you so much for this project (of cause I am a kickstarter baker).

  Because I could not wait I ordered a olimexino-stm32 board and espruino worked like a charm.

  But:

  I am unable to get PWM working on two pins simultaneously.

  // This works:
  analogWrite(D37, 0.02, {freq:1000});
  

  // This does not work:
  analogWrite(D37, 0.02, {freq:1000});
  analogWrite(D4, 0.02, {freq:1000});
  // --> D4 keeps LOW
  

  I am pretty sure this is a mistake on my part.

  Many thanks and sorry for my english :-)

  Graham

  EDIT:
  After two hours I found out, that it works with another pin combination, e.g. D37 and D36.
  Probably it does not work with pins with ADC functionality?!
