Frequencies are half of what I expect

[sison54]

I've tried this on both a MEGA2560 and an Uno and I get the same results. It seems that whatever frequency I set (4500Hz for example, I get around 2250Hz). I am using timer 1 and setting the frequency on the fly. Is there something I am missing? I can provide more detail if needed.

Thanks

Thanks for your interest and bug report.

I'm able to duplicate the issue, which happens to high frequencies above around 250Hz.

The bug has been found and fixed. The new release will be published soon, certainly with a note for your contribution.

Awesome, Thanks! Glad to know it wasn't me haha. Goes to show you if something seems wrong that it probably is lol. I sat on this for quite a while. I debated digging into to this myself to see if it was me or not, but i figured I would ask the question first because I figured you would be able to find the issue much faster.

Thanks again!

Be more confident next time that's you're correct, certainly after you've investigated / tested methodologically as you did. No one can be better than an oscilloscope in this situation.
My fault is that I thought this was designed / used / tested only for low frequencies.

Thanks to users like you 👍 , the library has been better and better, with less bugs.

Yup! I definitely tested as much as I could before asking, o-scope and all!. Thanks for all of your hard work!
