When I made the measurements, I found that outputting sine or triangular wawe the measurements were more accurate than with square wawe. Square wawe frequently gave double frequency on the Pico. Maybe I should have had some kind of attenuator or terminating resistor on the signal generator output?
I did also see fluctuations in the lowest numbers of the frequeny, but I tought it was due to my hobby level set-up.
When I measured with the PIO program about the same error-% was obtained. Again I thougt it was the contribution from my test set-up.
