is it possible to use your library with stm32?

I tryed to change it for using with stm32, but unfortunetly it not work
I made this changes in DaliBus.cpp

void DaliBusClass::begin(byte tx_pin, byte rx_pin, bool active_low) {
  txPin = tx_pin;
  rxPin = rx_pin;
  activeLow = active_low;

  // init bus state
  busState = IDLE;

  // TX pin setup
  pinMode(txPin, OUTPUT);
  setBusLevel(HIGH);

  // RX pin setup
  pinMode(rxPin, INPUT);
  //---attachPinChangeInterrupt(digitalPinToPinChangeInterrupt(rxPin), DaliBus_wrapper_pinchangeISR, CHANGE);
  attachInterrupt(digitalPinToInterrupt(rxPin), DaliBus_wrapper_pinchangeISR, CHANGE);

  // Timer setup
  //---Timer1.initialize(DALI_TE); // set timer to time of one half-bit
  //---Timer1.attachInterrupt(DaliBus_wrapper_timerISR);
  Timer1.pause();                                             // останавливаем таймер перед настройкой
  Timer1.setPeriod(DALI_TE);                                       // время в микросекундах
  Timer1.attachInterrupt(TIMER_UPDATE_INTERRUPT, DaliBus_wrapper_timerISR);  // активируем прерывание
  Timer1.refresh();  
  Timer1.resume();
}

Hi @gonzzzales!
I don't have a STM32 board or any experience with it.
I don't think either the TimerOne and PinChangeInterrupt libraries used in this library support STM32. But you can have a look at @thewhobox's pull request #13 (which I haven't found the time to review yet). It uses a generic timer library instead that also supports STM32. However, you'd still have to configure and test it for STM32 yourself.

Hey guys,

The Timerinterrupt_Generic Supports STM32.
Ist would need small changes to support it but thats easy.
I can add These changes to the pull Requests in the next days.

Hi @hubsif, any chance you could share more about how this would be set up with an arduino, from scratch? The wiring in particular is a complete mystery to me.

[gonzzzales]

@thewhobox i tryed to do it with rogerclarc core. In other projects Timer1 and pinchangeinterrupts work fine. My changes you can see above. Unfortunetly blink example didn't want to work))

[thewhobox]

I added support for stm32 in my pr #13 (or this branch).
Due to i dont own a stm board its not tested, but it compiles without errors.

[thewhobox]

@kubukoz you need a pcb to receive or send dali commands.
You can find circuits online (here for example) or buy a finished product (dali click, led-warrior or waveshare dali2).

Then its only conencting RX and TX from pcb to your microcontroller.

I did some testing with STM32F103C8 (Bluepill) and Thewhobox fork of the library.
For me code compiles ok with latest Arduino IDE, but execution fails. Basicly nothing happens.
Even only setting the built in led ON fails.

If I comment "#include <Dali.h>" then rest of the non DALI related code starts working.

Any suggestions how to debug more?

[thewhobox]

You could add some println to see where it crashes.
I suggest its in the begin method of the DaliClass.
There is all the code to start timer and initiate the pin interrupt.
