Example code does not compile on either Arduino Zero or MKR1000

[viggi1000]

Hey guys, I work on hobby projects mostly and got the Pulse sensor to do some biomedical hacks. While the example works on the older Arduino's(Mega,UNO), The code throws a lot of errors with newer arduino's like Arduino Zero, MKR1000 or the Adafruit M0 feather.

Will you guys be porting the code to newer arduino's? The sensor works great and would be awesome to work with this in the MKR1000's or the new arduino's. I'm unfamiliar with interrupts and stuff so I couldn't get it working again, I would really appreciate any help!

Here is the compilation error

Interrupt:27: error: expected constructor, destructor, or type conversion before '(' token

The timer interrupts are different between the two chip types (AVR vs SAM). The library used in the source code doesn't know about the boards you're trying.

@morefigs thanks for stating the obvious. It very clear from the question that is the problem. Why not suggest a solution?

If you're using an ARM uC, then please use the BPM_Alternative example sketch.
