Hi Martin,
thank you soooo much, it is working now!
You are so right, the problem was the micros() function of the MKR1010.
It was working as soon as I replaced the micros() against your awesome micros2() function inside the NewRemoteSwitch library.
But I do not understand the whole code of you... How does the TC3_handler function() work?.. How will that function be called?
Do you have some literature to understand that assembler code? I would like to understand that code.
Thank you very much!
With best regards,
Alexander
