Arduino nano rp2040 connect troubleshooting

[myazenko]

Hello, first thank you for your work on PulseSensor, it is a great tool. I first tried it with an arduino uno on a previous project, and everything went smoothly. However now that I've got a nano rp2040, the sketches won't compile (including the examples provided with the library). I get a bunch or errors, and looking at them I feel a bit out of my depth. Could you please help me figure it out ?

@myazenko We try to use hardware timer interrupts when we can. The RP2040 is not supported for hardware interrupts, and is rather new to us. That is why you are getting this error. I made changes to the PulseSensor Playground library. Please use the latest release, which you can find via the Arduino Libraries Manager, or you can download from here

https://github.com/WorldFamousElectronics/PulseSensorPlayground/releases

The latest version is 1.6.2 make sure that is the one you use! Place it in your 'libraries' folder in your sketchbook. What you need to do is use the Example called PulseSensor_BPM_Alternative.ino That one uses a software timer to acquire the signals.

Our current library version supports RP2040.
