[Resolved] PulseSensor_SP Library not compiling

Troubleshooting
1

I’m attempting to use a Pulse Sensor on my Photon, using the PulseSensor_SP community library, but it’s failing to compile on even an empty project.

This is my first time attempting to use external libraries so I’ve probably messed something up, but I cannot figure it out.

Here is the error I’m encountering:

I’ll have to have a look at the library, but I guess that lib brings some files which you imported otherwise again.

BTW, if you add a link to the respective libs, it makes investigating matters a bit easier :wink:

Can you provide a screenshot of your Build window with the code drawer (<>) open?

For me the sample coming with the lib builds fine

Here’s a picture of my project (well…there’s nothing in it now).

I originally tried to copy over the example, and, when that failed, I tried running it in an empty project.

Also, I’m sorry for the slow response - someone pulled the fire alarm in the dorm I live in.

You don’t need to copy over the sample.
You just select the lib, click on the respective sample file and press USE THIS EXAMPLE.

But I can’t see anything wrong in your screenshot - maybe shorten that project name a bit :wink:

After looking at the sample I found there is no #include "PulseSensor_Spark/PulseSensor_Spark.h" but a bunch of extern variables.
If you replace the automaticly added #include with this, the errors go away

#include "PulseSensor_Spark/SparkIntervalTimer.h"

extern int pulsePin;
extern int blinkPin;
extern volatile int BPM;;
extern volatile int Signal;;
extern volatile int IBI;
extern volatile boolean Pulse;
extern volatile boolean QS;
extern int fadePin;
extern int fadeRate;

I’m not sure what I was doing wrong, but I’ve got it working now. Thanks!

Edit: Well, now I know what I was doing wrong - thanks again!
