Thanks for the reply. I am an old fellow that grew up with Cobol and Fortran.
Not sure if I can do more than Arduino.
Hoping for easy.

While 20 bit PW resolution is super nice, the issue remains that the freq must be an integer so no dice on 7.83

Well the issue is freq must be an integer so no dice on 7.83. I need a version that allows floats or divide the master clock by 10.

ledcAttachChannel(7, freq, resolution, 3); //freq is an integer.

Thanks for the reply though

On a ESP32-S3, I want to create a simple clock output of say 7.8 Hz.

ledcAttachChannel(1,78,12, 2); //will give me 78 Hz quite nicely.
How can I divide the clock down by 10 or even 100? This is simple for some but I am so frustrated trying things.
Thanks Rick

Thanks for the prompt reply. A little jitter etc is all ok.
Can you offer any sample code to get started please?

I am keen about generating a square wave with a floating point frequency say 1 or 2 decimal points from the range of 1-20000 Hz.
Is there an easy way to do this say with a S3? 7.83 Hz for example.
Thanks

Where do I find the "driver/rmt.h" file? This is new to me.
Thanks
