The comments in the title block of SI5351.set_freq(freq, clk) say freq units are Hz. I think they are Hz*100ULL.

This is on line 180 of si5351.cpp. I believe the same issues occur with SI5351.set_freq_manual and probably other functions should be checked. This is important as VScode and other IDEs display those comments when you hover over the function call.

Thank you, I'll fix this in the next update, which shouldn't be too long now that I've got a lab again.

Thanks!

I've bumped into this one too and just changed the comment re. set_freq() params in my clone. It was a puzzle for a moment as I was sure the dividers must be set wrong. 🙃

Let me know if u want a pull; I'll make the fix on a clean fork (you don't want the hacked-up bits I use;).
