Arduino due doesn't work

hi this library doesn't work in arduino due:

@arashsoftco What sketch example are you using? Please try the BPM_Alternative.ino sketch.

I'm also having this issue when using the Due, I went to the Interrupts.h file and changed all instances of cli() to interrupts(), sli() to noInterrupts(). Now it works but it is reading extreme values when I'm 100% positive that the Arduino connections are correct due to the fact that it works on the Uno.

When I set the USE_ARDUINO_INTERRUPTS to false it started giving different extreme values. This leads me to the conclusion that this is a library issue. What could be the cause of this in the library other than interrupts?

[Sudomarko]

I'll look for more possible reasons, probably something with the timer code and upload it here. It would be really nice if you could direct me to the right place though.

@Sudomarko You are on the right track. I don't know if we need to use those defines. In the Interrupt.h file there are a number of board architectures specified that don't define a value for those items. This forum post has what looks like a good srtarting point for adding hardware timer support for the Due. https://forum.arduino.cc/t/timer-interrupts-on-due/127643/17

We want to sample the PulseSensor at 500Hz. (every 2 milliseconds). There are other places the code will need to be adjusted to add support for Due hardware timers, but just getting the timer to function is a big step.

Thanks, will keep you posted over the next couple of days.
