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
