Hi, I'm a beginner so forgive me if the problem has already been raised somewhere. How to control via Codesys on a raspberry pi 4 PWM on adafruit PCA9685 so as to be able to regulate the frequency during operation?
If I enter the value permanently, I see on the oscilloscope that for 600hz I physically have 531hz.
Unfortunately, it is not possible to change the frequency in flight.

Thank you in advance for your response
Hello,
Unfortunately I already ask the question here: https://forge.codesys.com/forge/talk/Runtime/thread/c18c2a8aa2/
Nobody seems to know something about this FB in Codesys... :-/
So I'm still waiting any info about it.
