In the migration documentation there is a link from 2. to 3:
https://docs.espressif.com/projects/arduino-esp32/en/latest/api/ledc.html
which is clearly described here:
bool ledcAttach(uint8_t pin, uint32_t freq, uint8_t ...

2 different PWM frequencies required, but ledcAttachChannel was not declared in this scope
I need two different frequencies for my project, 4KHz and 20KHz.
The use of:
ledcAttach(2, 4000,8);
ledcWrite(2, 127);
ledcAttach(10, 20000,8);
ledcWrite(10, 127);
deliver on both channels/Pins 20KHz;
