• Some interesting USB console behavior, I can't understand.

  I helped Andrey change project to fix this.
  1) In \Espruino\targets\linux\jshardware.c we cut function

  bool jshSleep(JsSysTime timeUntilWake)  {
  ...
  ...
  ...
  }
  

  to

  bool jshSleep(JsSysTime timeUntilWake) {
    return false;
  }
  

  2) In \Espruino\targets\mbed\jshardware.cpp

  bool jshSleep(JsSysTime timeUntilWake) {
     __WFI(); // Wait for Interrupt
     return true;
  }
  

  to

  bool jshSleep(JsSysTime timeUntilWake) {
     return true;
  }
  

  3) In \Espruino\targets\stm32\jshardware.c

  bool jshSleep(JsSysTime timeUntilWake) {
  ...
  ...
  ...
  }
  

  to

  bool jshSleep(JsSysTime timeUntilWake) {
     return true;
  }
  

  We have a working result. Thank you!

  If call setTimeout with value more than 12000, then this function execute immediately.
  How to fix this?

  Hi, Gordon, Hi all!
  It's me again.
  I have some question to community.
  STM323F4 includes USB-COM to connect with PC.
  But I did not get to use this feature.
  Now I'm use external USB-COM converter.
  Converter connected to pins {rx:A3,tx:A2}.

  My working code:

  Serial2.setup(9600, {rx:A3,tx:A2});
  

  Tried to use:

  USB.setup(9600);       
  

  and

  USB.setup(9600, {dm:A11,dp:A12});
  

  Can I use internal converter? How can I do this?

  Gordon can you explain why object setTimeout spend a lot of memory?
