PWM on ESP32

[Tom12]

Hi,

i need two PWM-Signals. The simples way is "machine.PWM" but there is the Problem. Signal 1 I can do it with "machine.pwm" but Signal 2 must invertet to Signal 1.
Can I use "Signal(PWM, invert=true)"? If I tried it, it doesn't work.
If I used a Timer, there are some Problems. For example its to slow...

May someone help me?

Using an external inverter may be more dependable in this case (e.g. 74HC14).

Hi,

I don't want to use an external oscillator though.

The 74hc14 is an inverter, not an oscillator. It just inverts the polarity of a signal. You may use it to build an oscillator, but that is not the primary application.
