Measureing Frequency with Arduino

[B.Korb]

Hello,

I tried to measure a frequency with continous analog input. It worked fine up to 50 Hz with 1 kHz Samplerate. More than 1 kHz seemed that it didnt work properly, don't know why.

But is there any possibility to measure a frequency or pulsewidth with digital input natively?

Kind Regards

pulseIn() but it's not implemented in LIFA.  You can easily add it though.  I think I may have done this in the past, try looking for other posts about this and see if you can find it.
