PulseSensorPlayground does not work on Arduino Uno WiFi Rev2

[Tommaarleveld]

Im trying to get a simple BPM reading using the Arduino Uno WiFi Rev2. When compiling I seem to be getting an error. I just need a serial reading. Is there a simple fix for this issue? Or do I need another Arduino board?

This is my error:

I am also using arduino UNO and its working perfectly.

@Tommaarleveld It looks like the Arduino Uno WiFi Rev2 uses the ATmega 4809. Previous versions used the ATmega 328. I may have to adjust the Library to handle this issue with the interrupt function. The issue with the Pulse variable has already been fixed.

I have just successfully compiled the latest library version against the Arduino Uno WiFi Rev2 and I am not getting this error. I pulled the PulseSensor_BPM example sketch and it seems to pass the compiler test. I don't have an Arduino Uno WiFi Rev2 on hand, but will get one soon to check that this will work. Please try again.
