  Any ideas what the library would actually do? Realistically I'm not going to be able to add drivers for 450 different boards :)

  Why not? ;-)

  I was only thinking about really small code examples for setting up the communication interfaces (UART, SPI or I2C) on the correct pins. Or even better, a kind of abstraction layer for modules compatible with the "mikroBUS" (spec here: https://download.mikroe.com/documents/st­andards/mikrobus/mikrobus-standard-speci­fication-v200.pdf)
  In page 6 is showed the pinout of the mikroBUS.
  I could be very cool to be able to get access to this by calling some thing like

  var mikroBUS= new mikroBUS();
  
  digitalPulse(mikroBUS.RST, 1, 5);
  mikroBUS.SPI.send("some data");
  analogRead(mikroBUS.AN);
  //and so on...

  The Mikroe ecosystem is evolving fast, with huge amount of plug-in boards (named Click. Currently, more than 450 Click boards so far).

  It would be very nice to get support of this Click-to-Arduino shield :-)

  Well thanks for pointing the note in the setWatchreference ! That's a good answer.
  It seems that this limitation can't be bypassed :-/

  whoops sorry, you're right. Corrected :-)

  Hi guys,

  I was discussing with my colleagues the problem of the NVIC multiplexer within the STm32 (and probably every CortexM) that limits the number of external interrupts.
  For example, EXTI1_IRQHandler can be triggered by any pin Px.1 (mutually exclusive) among the available ports, a limitation is therefore that you cannot enable an interrupt simultaneously on PA.1 and PB.1.
  Then came Espruino into the discussion, and we wondered how is it possible to do a setWatch on PA.1 in addition to another setWatch on pin PB.1?
  If possible, what is the trick? Does Espruino poll the inputs and generate virtual interrupts?

• Vote for Espruino features!

  I tried to talk to Espressif at embedded world - maybe I talked to the wrong people, but they honestly couldn't care less about Espruino

  How did you convice STMicro to support Espruino?

• Any chance of supporting the brand new STM32WB ?!?
