I have been having a hard time finding a solution to my problem. I copied code from Sparkfun’s hookup guide and I cannot get it to compile. I will admit I am not the best coding but I didn’t think Sparkfun would post code that would cause a problem. Error message I am getting is;

C:\Users\Red\AppData\Local\Temp\arduino_build_600700\sketch\Example1_config_BPM_Mode1.ino.cpp.o: In function `loop’:

Error compiling for board SparkFun RedBoard Turbo.

Is there away to debug the code? I tried pasting code into VS Code and use debug but not luck.

I used Example 1 code, get errors with the other examples also.

I don’t know where else to look to resolve my problem. I’m sure I’m over looking something simple.

Thanks, Doug

Try replacing Serial with SerialUSB in the sample code.

That did the trick!

P.S. could you please explain why adding USB to Serial worked?

Thanks, Doug
