PSoC™ 5, 3 & 1

[ansac_3800691]

Hello,

I have implemented the proposed method on the AN2283 site and fail to measure the frequency of a perfect 2 kHz sinus.

I checked out the external variable: bDataAvailable, wSaveCountNum,  cSaveOverFlow , wSaveTickNum  and they have the value 0x0000 or 0xFFFF.

Here are some prints and program code attached.

I appreciate your help

Best regards,

Andrei

Hi Andrei,

Is your input signal digital or analog?

Hi Kenny,

The input signal is analog.

Thanks!

Yes I think that's the issue.

You may have to pass your signal through a comparator first, to make it a square wave, then use that as the input-signal.

I did this and still 0 remains.

Can you check if you can see the signal at the output of the comparator?
