error compilation

[fotosettore]

hi !
really interested in this project !
board type in compiler : WeMos D1 R1.
unfortunately no compiling :-(
this is the error

c:/users/peppe/appdata/local/arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/2.5.0-4-b40a506/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld.exe: sketch\ClockController.ino.cpp.o: in function `_M_manager':

Errore durante la compilazione per la scheda WeMos D1 R1.

I saw that the error is made by line 49

AccelStepper hourStepper(hourStepForward, hourStepBackward);

in a previous test (some months ago) I used this line about the AccelStepper library (using arduino UNO)

AccelStepper hourStepper(AccelStepper::FULL4WIRE, 12, 27, 14, 26);

and it worked fine.
You see that line sintax is different.

where is my error ?

The FULL4WIRE interface uses AccelStepper's default 4 wire stepper interface. But the drive sequence for the BKA30D-R5 has contacts 2 and 3 always driven in phase with each other (i.e. it's a 3 wire interface).

So the AccelStepper constructor I use in this project defines a custom function so that you only need 6 GPIO pins from the Wemos D1 Mini, not 8. It looks like you haven't included that header file in your code?

In this case, about the code, I used yours without modification.
However I saw there are many links about Accelstepper :-(
It's possible that the one I used is wrong for the sketch you made.
Can you insert the link of the library you used?
p.s. Your project is really interesting because uses a dedicated void and a photocoupler to set the clock for start.
